High-quality clamping screw that accepts a wide assortment of swivel feet (order foot separately). Socket-head version allows applying strong clamping force using a hex wrench. Available in zinc-plated steel with thread sizes from 1/4-20 to 5/8-11. Available in black-oxide-finish steel with thread sizes from 1/4-20 to 5/8-11 (M6 to M16 in metric). Available in stainless steel with thread sizes from 1/4-20 to 1/2-13. Choice of several lengths in each thread size. Made in the USA.
Swivel Head 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. Note: Delrin® feet are not threaded – they snap on and off.
For full hex-socket strength, the socket end of the body should be entirely inside its tapped hole during final tightening.
