Other threaded fasteners
Here are some other types of threaded fasteners
Thread rolling screws - have a lobed (usually triangular) cross section. They form threads by pushing outward during installation. They may have tapping threads or machine threads.
Superbolt, or Multi-Jackbolt Tensioner Alternative type of fastener that retrofits or replaces existing nuts, bolts, or studs. Tension in the bolt is developed by torquing individual jackbolts which are threaded through the body of the nut and push against a hardened washer.
Installation and removal of any size tensioner is achieved with hand tools, which can be advantageous when dealing with large diameter bolting applications.
Hanger Screw – A headless fastener that has machine screw threads on one end and self apling threads on the other designed to be driven into wood or another soft substrate.
