Threaded Detent Pins have one end threaded for a knob handle. These quick-release alignment pins have a solid shank and spring-loaded locking balls. 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. Available in stainless steel only. Made in USA.
