Product Information

Marine Detent Pins

Marine Detent Pins are made of 316 stainless steel for extra corrosion resistance. Economical quick-release alignment pin with a solid shank and spring-loaded locking balls. This type of Detent Pin has a ring instead of a solid shoulder, for applications where exact grip length is not important. Locking balls hold the pin in place by spring force (not positive locking like a Ball Lock Pin). Simply push the pin to insert, and pull to remove. Made in USA.

Available in pin diameters from 3/16 to 1/2" (6 to 12mm in metric), in stainless steel only. Standard grip lengths for each diameter are listed in the tables below, most in stock for same-day shipment. Marine Detent Pins with special grip lengths up to 12” (300mm) can be quickly made to order. The Part Configurator link at the top of this page can be used for any Marine Detent Pin, either standard or special.

Technical Information

Locking balls hold the pin in place by spring force. Simply push the pin to insert, and pull to remove. 3/16"-diameter pins have only one locking ball instead of two due to their small size.

Application Information

These Detent Pins are made of 316 stainless steel for extra corrosion resistance in marine environments.
