YIWAN Hardware is a custom door lock parts manufacturer producing metal components for OEM and industrial applications. Our manufacturing capabilities include multi-station cold heading, CNC machining, turning, and punching, with a product range covering door lock parts, pins, rivets, screws, nuts, and other customized hardware.
For lock manufacturers and hardware sourcing teams, a component has to do more than match an outline. A pin must fit its mating hole, a screw must engage correctly, and a rivet must secure an assembly without restricting movement. Those requirements start with the drawing—and with choosing a manufacturing process suited to the part.

Custom Door Lock Parts for OEM Sourcing
YIWAN Hardware—Yueqing Yiwan Hardware Production Co., Ltd.—manufactures customized metal components rather than treating every sourcing request as a standard catalog purchase. Our product catalog includes door lock pins and door lock screws alongside related fasteners, sleeves, and special-shaped parts.
If you are developing a new lock assembly or sourcing a component for an existing design, start with the individual part specification. A description such as “door lock pin” identifies the application, but it does not define the diameter, shoulder position, material, or fit required for production.
Door Lock Pins and Related Precision Parts
Pins can locate components, provide pivot points, or retain parts within an assembly, depending on the design. YIWAN’s catalog includes door lock pins, stepped pins, and stainless steel knurled pins.
For a custom pin inquiry, identify the working diameter, overall length, shoulder dimensions, grooves, and end features. Where a pin rotates or slides, specify the relevant fit and surface requirements. Where it is pressed into place, identify the mating material and retention requirement rather than relying on diameter alone.
Door Lock Screws and Custom Fasteners
YIWAN’s screw range includes door lock screws, set screws, stepped screws, and customized screws. These product families provide a starting point for discussing fastening requirements in lock and hardware assemblies.
A useful specification includes thread size and pitch, thread length, head geometry, drive type, and material. Note any clearance restrictions around the screw head. If a coating is required, define the finished-part requirements so thread engagement and assembly fit can be evaluated together.
Rivets, Nuts, Sleeves, and Special-Shaped Hardware
Our wider hardware range includes semi-tubular rivets, stepped rivets, embedded nuts, cylindrical sleeves, and customized irregular parts. For a lock project using these components, suitability depends on the drawing and the role each part plays in the assembly.
For example, a riveted pivot needs enough retention to hold the assembly together without creating excessive resistance to movement. A sleeve needs the correct relationship between its internal diameter, external diameter, and length. Providing that functional context helps make the quotation more meaningful than a price based on an approximate shape.

Manufacturing Processes for Custom Lock Components
The right production method depends on geometry, material, dimensional requirements, and quantity. YIWAN combines several manufacturing processes, allowing inquiries to be considered against more than one production route.
Multi-Station Cold Heading
Cold heading forms metal through a sequence of forming operations. For suitable fastener-like geometries and production volumes, it can reduce the amount of material that must be removed by machining. Tooling requirements and material formability influence whether it is an appropriate choice.
A headed pin or rivet may be a candidate for this process, but the decision should follow a review of the complete part—not simply its product name.
CNC Machining and Turning
CNC machining and turning are relevant to components with defined diameters, shoulders, grooves, threads, or other machined features. They can also provide a route for geometries that are not economical to produce entirely through forming.
The important question is which features control assembly performance. A close-fitting diameter may need a different level of dimensional control from a non-contact external surface. Identifying that distinction helps avoid unnecessary machining cost while preserving the function of the part.
Punching and Supporting Operations
YIWAN’s published capabilities also include punching. Depending on the design, a component may require forming, material removal, or a combination of operations. Any secondary-operation and finishing requirements should be included in the inquiry and confirmed for the specific project.
Define Precision Around How the Lock Works
When comparing a door lock parts manufacturer, ask how the quotation addresses the features that matter in your assembly. A general claim of “high precision” is less useful than an agreed drawing with clear acceptance requirements.
Consider a stepped pin passing through two moving components. The working diameter affects clearance; the shoulder length affects axial movement; and burrs at an edge may interfere with assembly. Tightening every dimension equally is unlikely to be the most economical solution. Defining the functional dimensions is a better starting point.
For threaded parts, specify the thread standard and any required gauging. For moving or mating surfaces, identify roughness and edge requirements where relevant. Where a finish affects dimensions, make clear whether the acceptance limits apply before or after finishing.
For a new component, discuss sample evaluation before committing to a production order. Dimensional approval and assembly testing answer different questions: a part can meet an incomplete drawing and still fail to perform as intended in the finished lock.
Material and Finish Requirements
Material selection should reflect the component’s load, movement, environment, and contact with other materials. YIWAN’s broader catalog includes stainless steel hardware, carbon steel screws, and brass or copper components. Availability of a particular grade for your lock part should be confirmed during quotation.
Stainless steel may be appropriate where corrosion resistance matters, but the grade and service environment still need to be specified. Carbon steel may suit some fastening and structural applications, with protective treatment considered where needed. Brass may be relevant to certain machined components, depending on the mechanical and environmental requirements.
Avoid specifying a finish only by appearance. If your project requires a coating thickness, corrosion test, restricted-substance declaration, or other documented requirement, include it in the RFQ and ask for availability to be confirmed. A silver-colored finish, for example, does not by itself establish corrosion performance.
How to Request a Quote for Custom Door Lock Parts
A complete RFQ helps a manufacturer evaluate feasibility and makes competing quotations easier to compare. When contacting YIWAN, include:
- A dimensioned drawing and revision number: Add a 3D model if available, and identify any dimensions that control fit or movement.
- Material and finish requirements: State the grade, required treatment, and whether dimensional limits apply after finishing.
- Quantity: Provide the initial order quantity and expected repeat demand, if known.
- Application details: Explain what the part does and identify relevant mating components or assembly constraints.
- Quality and delivery requirements: Include requested inspection documents, sample requirements, packaging needs, destination, and target delivery date.
If you only have an existing part, start by sending photographs and available measurements. Ask what additional information or physical sample is needed before production can be quoted accurately. A photograph alone cannot establish a material grade or a close dimensional tolerance.
When comparing offers, review tooling, samples, finishing, inspection, and packaging as well as unit price. A lower price is only useful if it covers the specification you actually need.
Why Consider YIWAN as Your Lock Hardware Supplier?
YIWAN brings together a broad small-metal-parts portfolio and multiple manufacturing processes. Door lock pins and screws sit alongside rivets, nuts, turned components, and customized hardware in our product range. That makes YIWAN a relevant supplier to approach when your sourcing requirement involves individual metal parts rather than a complete lockset.
For an OEM buyer, the practical next step is a component-level discussion: what must the part do, which dimensions control that function, and what quantity is required? Sharing that information allows the conversation to focus on manufacturing suitability and quotation scope instead of generic product descriptions.
Frequently Asked Questions
Does YIWAN manufacture door lock parts or complete door locks?
YIWAN’s published offering includes door lock parts and custom metal hardware, with catalog categories for door lock pins and door lock screws. This page focuses on individual components for lock assemblies, not complete locksets.
Can I inquire about a non-standard door lock component?
Yes. YIWAN manufactures customized metal components. Send the part drawing, material, quantity, and application requirements so the proposed component can be discussed against the available manufacturing processes.
What is the minimum order quantity for custom lock parts?
MOQ needs to be confirmed for the individual part. Geometry, material, tooling, and the proposed production method can affect the practical order quantity. Include both your initial requirement and expected repeat volume when requesting a quote.
How long will samples and production take?
Request project-specific timing during quotation. Drawing review, material availability, tooling, finishing, and sample approval can all affect the schedule. If you have a launch or assembly deadline, state it in your initial inquiry.
Can custom parts be made to a specific tolerance or testing requirement?
Submit the required tolerances and tests with the drawing for review. Feasibility and any supporting documentation should be confirmed for the specific component before an order is placed. Component conformity should not be treated as certification of the complete lock assembly.
