Captive Locating Screws

Captive & Clamping Pins

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 its fully retracted position, the bushing's spring clip snaps into the body's radial groove. This holds the screw fully retracted by the force of the spring and positively prevents removal. Pressure from the spring also holds the screw in intermediate extended positions. This is especially an advantage if the fixture is turned upside down. Captive locating screws are available in thread sizes from 1/4-20 to 1/2-13 (M6 to M12 in metric) and screw lengths from 1-1/4 – 3” (30 – 75mm in metric). Carr Lane Locating Screws are proudly Made in the USA.

The complete assemblies listed below include a Captive Locating Screw, Locking-Pin Bushing, and Lockscrew. Choice of standard or long bushing in most sizes, for installation in thinner or thicker plates. Locking-Pin Bushings are designed to press fit in a standard reamed hole and can be further secured with the included Lockscrew to positively hold the bushing in place.
