Ball Lock Pins

Description

FEATURES: Precision alignment pin with a ground shank. This popular single-acting type is positive locking until released by pushing the button, which moves the center spindle forward to allow the locking balls to retract into a radial groove. This type has the widest range of types and sizes. Available in steel or stainless steel. Made in USA.
