Provide the pin diameter, mating-hole size, host material, desired retention behavior, insertion method, and whether the assembly can tolerate local deformation. A press fit is a system decision: the same pin feature can behave differently in aluminum, steel, plastics, or thin-wall parts.
Yes. These features can be evaluated from your drawing. Specify thread standard and usable length, groove dimensions and retaining hardware, or knurl pattern, knurled length, host material, and assembly method. This avoids treating a retention feature as a cosmetic detail.
Yes. For locating pins, provide the required locating diameter, effective locating length, mating-hole tolerance, insertion condition, end form, and any shoulder or mounting feature. The key question is how the pin positions the assembly and whether it must be removable, press-fit, or repeatedly cycled.
Send a 2D drawing and 3D CAD model when available, plus material, quantity, pin function, critical diameters, length, mating-hole details, fit requirement, finish, and inspection needs. For pins with grooves, threads, knurls, or cross holes, identify their functional relationship to the main pin axis and datum.
Custom contact and connector-style pins may need controlled geometry, conductive material, plating, slots, crimp features, or assembly interfaces. Define the electrical function, mating connector, contact area, material grade, finish, and inspection requirements so mechanical and connection details are considered together.
Pivot, hinge, grooved, and retaining pins connect moving subassemblies in equipment where vibration, load direction, lubrication, and maintenance access matter. Your project review should identify the bearing length, retention method, contact surfaces, and any wear-sensitive dimensions before production.
Locating, shoulder, and dowel-style pins help establish repeatable positions in jigs, fixtures, grippers, actuators, and automated stations. Send the datum scheme, insertion cycle, load, and replacement requirement so the pin is reviewed as part of the positioning system, not as an isolated rod.
Steel may suit strength and wear requirements; stainless steel may be considered for corrosion exposure; aluminum can reduce weight; brass or copper alloys may support conductivity or corrosion-related needs; and engineering plastics may suit insulation, noise, or low-friction requirements. Finish selection should follow the duty cycle, mating materials, corrosion environment, contact surface, and assembly method rather than appearance alone.
For related drawing-based components across the same assembly, explore CNC Machined Components.
A 3D CAD model and 2D drawing are preferred. Include material, quantity, ID/OD tolerances, fit requirements, surface finish, application, and any inspection or packaging needs.
Yes. Samples help verify shaft fit, press fit, friction, noise, and assembly sequence before repeat production. Share the immediate quantity and expected future demand so inspection and production requirements can be planned.
