Custom Locating Pins Beyond Standard Catalog Parts

A standard dowel may be the right answer when the application needs a common diameter, length and end form. A custom locating pin becomes relevant when the function requires a controlled shoulder, relief, taper, thread, groove, cross-hole, installation feature or non-standard relationship to a mating bushing.

Start With Function, Not the Part Name

State whether the pin locates, pivots, guides, locks, carries shear load or is repeatedly inserted and removed. Identify the mating hole or bushing, installation method, service motion and replacement expectation.

Features Worth Reviewing

Stepped, shouldered, relieved or threaded pins
Small cross-holes, flats, slots and retaining features
Different functional diameters on one coaxial part
Ends designed for installation, extraction or orientation

Requirements That Need Special Attention

Hardness or wear requirements after heat treatment
Tapers, rolling contact or safety-critical pivot functions
Burr limits at cross-holes and edges near a mating surface
Press-fit dimensions that depend on housing material and installation
Standard catalog hardware requested without a clear custom requirement

What to Include

Controlled drawing with the functional datum and mating interface
Material, condition, heat treatment, coating and surface requirements
Installation, load, motion, wear and failure information
Critical edge, burr and inspection requirements
Prototype, production and annual quantities

Custom geometry does not automatically make a pin suitable for Swiss-type machining. Process and inspection fit are confirmed after review.
