Where this design fits

Locating fixtures and assemblies combining alignment with retention.

What to include in the RFQ

Provide the mating hole and assembly direction. Confirm which feature locates and which provides the clamp.

Material and acceptance

Carbon steel, 10B21, SUS304/316, aluminum, copper/brass and titanium alloy requirements can be discussed. Suitability is specific to the part, grade and process.

Define material condition, coating, critical dimensions and required inspection records. A named product family does not imply a tested load, pressure or performance rating.

RELEVANT PROCESS OPTIONS

Make the features work together.

These routes are options for technical review. The approved drawing, quantity and material determine the actual sequence.

Drawing and sample checks

Reference pin position to the mounting datum
Verify alignment and insertion with the locating hole.

Relationship of pin to thread and shoulder

Show pin diameter, projection and position relative to the locating datum, not only to the overall outline. Review the assembly path so the pin can engage before the screw reaches its seated condition. The locating function and thread retention need independent acceptance checks.

Review the route before fixing the quotation

For screws with integral locating pins, review Swiss-Type & CNC Turning, Secondary & Precision Operations, CCD Vision & Dimensional Inspection against the drawing and quantity. Identify which features can be produced in the initial shape and which require a separate setup. A change to a functional shoulder, bore, drive or thread can change the proposed route as well as the inspection effort.

The drawing review should resolve pin location; pin geometry; feature relationship. Keep material condition and finishing allowance attached to those requirements. Define the acceptance condition for critical features and approve any proposed dimensional change before comparing samples with the original assembly.

From drawing to approved samples

Provide the mating hole and assembly direction. Confirm which feature locates and which provides the clamp. Identify the drawing revision, prototype quantity and expected repeat demand. Where the first part is based on an existing sample, separately confirm material and hidden features rather than inferring them from appearance.

The typical sampling lead time, including tooling, is approximately 10–15 days. The schedule is confirmed after drawing review and agreement on the sample specification; material availability, special treatment and inspection requirements can affect the confirmed date. Confirm when the agreed schedule starts in the quotation. Sample approval and repeat-production delivery are separate milestones.
