Carr Lane CL-8-CLTA-2.00 | 1/2"-13 Thread Size x 1/2" Diameter x 2" Screw Length Captive Locating Screws with Adjustable Torque Knob

Product Information

New item! Also available in metric! These Captive Locating Screws have an integral adjustable knurled knob for tightening by hand. Knurled knob captive locating screws exerts positive, repeatable force. Clockwise, the knob de-clutches and turns freely when you reach the desired torque. Counterclockwise, the knob locks for positive retraction. 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 (M6 to M12 in metric). 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. Made in USA.

In fully retracted position, the bushing's spring clip holds the Locating Screw fully retracted by spring force and positively prevents removal. Spring pressure also holds the screw in intermediate extended positions.

Adjustment Information

To set desired force, first remove the outer cover screw at the side of the knob, to expose the adjustment screw. Next, insert a hex wrench to turn the adjustment screw until desired torque is achieved. Reinstall the outer cover screw when finished. Torque can be adjusted from 3 to 6 inch-lbs, resulting in a contact force of 10 to 125 lbs, but these values are approximate. Force can vary +/- 30% depending on lubrication and other operating conditions.
