Custom Fasteners Manufacturer
Yueqing Yiwan Hardware Production Co., Ltd. supports custom fastening projects from a drawing, sample or application requirement. The company manufactures rivets, pins, screws, nuts, cold forged parts, CNC parts and other metal components for OEM and industrial assemblies. This page explains the information needed for review, the production processes represented by the factory and the records available on the YIWAN website.
A drawing-led route for custom fasteners
A custom fastener cannot be quoted reliably from its product name alone. Head form, drive, thread, shank, material, finish and the way the part locates in the assembly all affect the result. YIWAN therefore works from a dimensioned drawing, stable sample or combination of the two. A photograph can explain the application, but the functional dimensions and acceptance points need to be documented.
The review starts with the mating parts and the job the fastener performs. A screw may clamp a bracket, a pin may locate a hinge component, a rivet may join a low-profile assembly, and a nut may provide a retained thread. The drawing should show the surfaces that seat, the features that clear surrounding hardware and the direction of installation. Tool access and the ability to reach both sides of the joint should also be considered.
Why drawing-led review matters
Small changes to a head, shoulder, thread or tail can alter fit and assembly. A drawing-led review keeps the buyer and production team on the same revision and gives inspection a clear basis. The approved drawing should be stored with the reference sample and later order information.
Manufacturing capabilities
YIWAN’s existing capability descriptions include multi-station cold upsetting or cold heading, CNC machining, automatic lathes, manual instrument processing and punching. The suitable route is reviewed after the part geometry, material and required features are understood. The process is selected to suit the drawing rather than being chosen automatically from the product family.
Multi-station cold upsetting and cold heading
Cold forming can be reviewed for fasteners and metal components whose shape can be developed through a forming sequence. Material, head form, shank form and any locating feature are considered together. CNC machining and automatic or manual turning may then support the features, tolerances or quantities that require a machining route.
CNC machining, automatic lathes and punching
CNC machining and automatic lathes can be considered when the drawing calls for turned profiles, bores or other machined details. Manual instrument processing is available for work that needs a manual production review, while punching can be considered where the geometry and material suit that process. The selected route should protect the functional faces and avoid assigning a finish or tolerance that the drawing does not support.
Product families supported by YIWAN
The site’s product families cover custom rivets, pins, screws, nuts, cold forged parts and CNC parts. Rivets include semi-tubular, tubular and hollow, step, Chicago and flat-head examples. Pins include hollow pipe pins, locating pins, stepped pins and knurled pin designs. Screws include hex socket, slotted, Phillips, set, step, irregular, door-lock and other hardware forms. Nuts include hex, knurled, embedded, cap, square, rivet and T-nut designs.
Cold forged parts and CNC parts support projects that require a drawing-led metal component outside a standard family. Use the rivets category, screws category, nuts category or custom parts category to review representative work before sending a project requirement.
From drawing to quotation
Send the drawing or stable sample, expected quantity, material and finish requirement, mating-part information and any inspection or packaging requirement. The drawing should identify the revision, critical dimensions and the surfaces that matter in assembly. If the project is not yet ready for a dimensioned drawing, describe the application and include clear photographs so the initial review can identify what is still missing.
What happens during the review
The geometry is checked against the intended manufacturing route. Material and finish are reviewed with the application, appearance and corrosion requirements. The team then identifies the functional inspection points and any drawing questions that need an answer before quotation. MOQ and lead time are confirmed per drawing in the quotation; no numerical MOQ or delivery period is published without project-specific information.
Information to prepare for quotation
- Dimensioned drawing or stable sample
- Material and surface finish requirements
- Expected quantity and repeat-order expectation
- Mating-part dimensions and installation access
- Inspection, handling or packaging requirements

Testing and exhibition records
YIWAN publishes a Certifications & Test Reports page with the certificate and test-report images already shown on the website. It includes a salt spray test report for review without substituting an assumed certificate number or test result. Exhibition photographs and event pages are collected in the Exhibitions section, where visitors can review examples of the team meeting hardware and manufacturing buyers at trade events.
For a production project, the usable evidence is the approved drawing, agreed material and finish, and the inspection requirement for the finished part. The drawing-led process keeps those points visible from quotation through inspection, so a catalogue image is not treated as a complete custom specification.
Frequently asked questions
What can YIWAN review from a drawing or sample?
The drawing or sample is reviewed for geometry, material, surface finish and the assembly interface. Send the expected quantity and any inspection or packaging requirement with it.
Which production processes may be considered?
Project review may consider multi-station cold upsetting or cold heading, CNC machining, automatic lathes, manual instrument processing and punching. The route is selected after the drawing and requirements are reviewed.
Can a custom part be quoted without a dimensioned drawing?
Photos or a sample can support the initial review, while a dimensioned drawing or stable sample is preferred before production details are confirmed.
Where are testing and exhibition records available?
The homepage Certifications and Test Reports section includes a salt spray test report. Exhibition photos and event pages are available in the Exhibitions section.
