Stainless steel quick-release pin THFR series

Overview
These threaded receptacles provide a permanent mating hole for quick-release ball lock pins. They are designed to be installed by threading into a base with a lock nut or for blind-hole installations. Grip Length Reduction is the portion of the pin that is contained inside the receptacle and thus reduces the usable pin length by that amount. Manufactured from heat-treated 303 stainless steel. Lock nuts must be ordered separately.
