Adjustable-toque thumb screws exert positive and repeatable force. When turned clockwise, the knob disengages and rotates freely once the desired torque is reached. Turning it anti-clockwise locks the knob for secure retraction. Adjustable-Torque Thumb Screws come with a swivel foot option and a knurled check nut. These screws are available in body-thread sizes ranging from #10-32 to 5/8-11 (M5 to M16 in metric), with various length options.

Knurled-head thumb screw that exerts positive, repeatable force. Clockwise, the knob declutches and turns freely when you reach the desired torque. Counterclockwise, the knob locks for positive retraction. Adjustable-Torque Thumb Screws are furnished with your choice of swivel foot, and a Knurled Check Nut.
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.
Choice of four foot types. Adjustable-Torque Thumb Screws use our patented left-hand-thread swivel-foot system. The ball end of the body screws into the foot for easy installation and removal. Once the ball threads pass beyond the foot threads, the foot can rotate and pivot freely (20° total angle). Foot threads are left-hand to positively prevent accidental backout during use. Delrin® feet are optional for types A and B. To order with a Delrin® foot, add “N” to the part number, e.g. CL-415-TSAN. Note: Delrin® feet are not threaded – they snap on and off.

Slotted Locator Bushings are compatible with various alignment and locating pins to align two holes without binding. These precision bushings feature a tight tolerance in one direction and full relief in the perpendicular direction. . Available for pin diameters ranging from 3/16" to 1/2". An optional version in hardened 440C stainless steel is also available. These are available in knurled and press fit type.
Adjustable-torque thumb screws exert positive and repeatable force. When turned clockwise, the knob disengages and rotates freely once the desired torque is reach. Turning it anti-clockwise locks the knob for a secure retraction. These can be used as a controlled-torque nut or as a thumb screw by fitting a custom screw in the tapped hole. Available in both metric and imperial sizes.
A precision locating pin is commonly used with a matching bushing to align two parts of a fixture. The pin’s head and shank diameters are concentric within .0005" TIR. Available in pin diameters of 1/4", 5/16", 3/8", and 1/2" (6mm, 8mm, 10mm, and 12mm in metric). A precision bushing is used with a Bullet-Nose Dowel to align two components of a fixture. The bushing’s ID and OD are concentric within .0003" TIR. Available for pin diameters of 1/4", 5/16", 3/8", and 1/2" (6mm, 8mm, 10mm, and 12mm in metric).
Carr Lanes shoulder screws are a type of fastener that are manufactured with a cylindrical body and a shoulder between the threaded portion and the head of the screw. The shoulder is larger in diameter in comparison to the threaded area and is a bearing surface or precise reference point. This item is available in both metric and imperial sizing and in thread diameters from 1/4" to 3/4" (8 to 20mm). These shoulder screws are best used for critical applications where precision and performance are vital.
Durable swivel head screw designed to accommodate various swivel feet. The knurled head ensures a secure grip, allowing for easy hand tightening in light clamping tasks. Knurled-head swivel-screw assemblies that combine the bodies and feet also in this category, available in multiple sizes and materials. Swivel head screws are available in four different variants, which includes small foot, large foot, ball foot, and bodies for swivel had screws. These are available in steel, stainless steel and steel with black oxide finish.
Depending on extended screw length, these threaded alignment pins can be used for clamping and locating, or clamping only. The clamping bushing is made separate from the pin, and is required to be welded in place at the proper length to fit the application. These are available in thread sizes from #10-32 to 1/2-13 (M6 to M12 in metric)
