8mm x 50mm Stainless Steel Quick Release Detent Pin

8mm x 50mm Quick Release Detent Pins - 304 Stainless Steel | Vital Parts - QRDP007

Our Quick Release Detent Pins are made up of a stainless steel shaft and two spring-loaded stainless steel ball bearings. To use this variation, tug at the pull ring to compress the springs which in turn retracts the ball bearings and allows the pin to be easily removed.

The pull ring offers two functions during use: it acts as an attachment point for a retaining chain to prevent loss and serves as a means of removal thanks to its smooth finish and compact design. Manufactured from 304 stainless steel, these detent pins are durable, corrosion resistant and designed for long-term use in demanding environments.

What Are Quick Release Detent Pins?

Quick Release Detent Pins are tool-free fasteners used to secure or position parts that need regular adjustment. Their self-springing design and simple pull-release operation make them ideal for high-traffic or serviceable areas. This variant is designed to be inserted into a hole 0.1mm larger than the body diameter for proper engagement.
