Phillips-drive pointed screws with a cross drive and tapered point for locating and fastening in equipment and hardware. The notes below focus on the features that need to be confirmed before a drawing is approved.
Cross recess and tapered point
This Phillips-drive pointed screw combines a cross recess with a tapered point. The point can guide the screw into a mating feature, while the recess provides the installation drive. Neither feature replaces the correct thread or a properly sized hole.
For phillips-drive pointed screw, use the photograph only to identify the family. Mark the features that must be measured, the ones that may be visually compared and the surfaces that must remain free of damage in the approved drawing.
Point and lead-in
Check the point angle, tip condition and the lead-in it engages. A point that is too long can reduce thread engagement, while a blunt or damaged tip can fail to locate. Show the point geometry and the first thread position on the drawing.
At every change of section on phillips-drive pointed screw, decide whether the transition is a clearance, a locating fit, a spring point or a stress-sensitive area. The radius, chamfer and undercut should then be specified to match that function.
Thread and seating
Specify the thread size, pitch, direction and usable length. Identify the surface that seats and any clearance around the head. For a pointed screw, confirm that the mating hole or component is suitable for the point and that the screw does not bottom before seating.
For a part that will be serviced, check that phillips-drive pointed screw can be released without damaging the mating component. A recessed drive, adhesive patch or locking feature can make removal harder than installation and should be reviewed at the same time.
Material and finish
State the base material, finish and any thread treatment. Do not infer a grade from the color. If the point is a locating surface, define its finish and allowable marks. A plated point can change how it enters the mating feature.
Compare finish changes for phillips-drive pointed screw against the approved sample under the agreed viewing condition. Record the surfaces where coating build-up, color variation, marks or edge coverage are acceptable, and keep that reference with the drawing revision.
Assembly trial
Trial the screw with the actual driver and mating part. Confirm that the point enters without forcing, the thread engages and the intended face seats. Inspect the point and recess for damage after assembly.
After the trial, protect the approved sample of phillips-drive pointed screw from handling damage and keep it with the current drawing. Any process, material or finish change should be compared with that reference before the lot is released.
FAQ
Does a pointed tip create its own thread?
Do not assume that. The thread and mating hole must be specified for the application.
Can the point be used as a drill?
No. A pointed screw should be matched to a prepared hole or mating feature; it is not automatically a drilling fastener.
What should be checked on the point?
Check the angle, tip condition, lead-in fit and the amount of thread engagement that remains.
