A clevis pin provides a cost-effective fastening solution which allows the supported objects to rotate about the clevis pin axis. They are commonly used as a secure, fast replacement to bolts or rivets. Technifast clevis pins are supplied to ISO 2341B (DIN 1444) with a cross-drilled hole for R-clips or cotter pins which when inserted, keep the clevis pin in place.

We also stock a range of ISO 2341 clevis pins with grooves for Circlips to DIN 471. We produce clevis pins in a variety of materials including mild steel (zinc plated), stainless steel A1 and stainless steel A4. We are also a UK manufacturer of custom-made and non-standard clevis pins, which can be made to customer specifications or drawing and in different materials. 

We can produce clevis pins with a head diameter of up to 32mm, and adapt the hole size and grip length to suit customer requirements. Our manufactured clevis pins are all turned, rather than cold-headed, to provide a more superior finish. Please contact us for more information and latest pricing.

Clevis Pin Grip Length: ISO 2341B

Our team often get enquiries on the grip length of clevis pins. The standard is quite confusing as it gives a measurement to the centre of the hole. The table opposite gives a quick guide on our most commonly used standard clevis pin ISO 2341B.

To calculate the grip length on the shaft of a clevis pin, simply subtract the number from the length you are looking to order. So for example a 10 x 50mm clevis pin would have a grip length of 50mm – 5.1mm. Giving the grip length to be 44.9mm.  Should you require any guidance, please contact us for assistance.
