How to Choose the Right Pin
Define the function first: dowel pins for precise alignment, cotter pins for locking nuts and clevis assemblies, spring pins for resilient, vibration-resistant joints, and taper pins for removable yet secure hub-to-shaft fits. Match the pin diameter to the hole tolerance class (m6, h7, etc.) and select the material grade for the load and environment. Send us your application and hole dimensions, and our engineers will specify the correct pin type, tolerance and finish.
Frequently Asked Questions
What pin standards do you supply?
We manufacture ISO, DIN, GB and ANSI pins, including parallel, taper, cotter, clevis and spring types in metric and imperial sizes.
What tolerance should I specify for dowel pins?
Typical fits are m6 or h7 depending on the assembly. Provide the mating hole tolerance and our engineers will confirm the correct pin diameter class.
Can you supply custom-length and custom-material pins?
Yes — custom lengths, diameters, materials and surface finishes are available for OEM projects.
Do you offer stainless steel pins?
Yes, A2 and A4 stainless pins are available for marine, food and chemical applications.
