Carr Lane Manufacturing Co. Captive Locating Screws

Captive Locating Screws can be used for locating and clamping, or for clamping only, by selecting the appropriate screw length. The locating screw's precision-ground body is positively retained in a locking bushing. In fully retracted position, the bushing's spring clip snaps into the body's radial groove. This holds the screw fully retracted by spring force and positively prevents removal. Spring pressure also holds the screw in intermediate extended positions, an advantage especially if the fixture is turned upside down. Available in thread sizes from 1/4-20 to 1/2-13. Made in USA. Locking-Pin Bushings are designed to press fit in a standard reamed hole. Secure with the included Lockscrew to positively hold the bushing in place. Shorter or longer bushings are available in most sizes, for thinner or thicker plates.
