Hanger Bolt

For a secure fit, thread a stud into your part after attaching an extension spring to it. 

To keep the spring straight and correctly coiled, the head rotates 360 degrees. For a secure fit, thread a stud into your part after attaching an extension spring to it. Anchors feature wrench flats at the top of the threads and a hex socket on the bottom to facilitate tightening. 

These studs, often called hanger bolts, are used to mount, suspend, and secure components to wood constructions. Use a stud driver to install them, or thread two nuts onto the stud and jam them together to make wrench flats.

These multipurpose hangers, also called spade bolts, can be fastened with a nut like a bolt or inserted into a threaded hole like a screw. 

For use with threaded rods, bolts, and anchors, these hangers feature internal threads. 

Hammer these hangers into place after drilling a hole in concrete or another hard surface. After inserting the hanger, the base will expand when the head is pulled with a hammer's claw, securing the hanger in place. 

Make use of an adjustable wrench to drive these hangers into wood.
