Socket fasteners are socket driven fasteners used for their ability to receive high torque forces from a hex wrench. Socket fasteners include screws, bolts, set screws and shoulder bolts. Socket cap screws, perhaps the most common type of socket fasteners, are used in machine parts, die fixturing, and clamping. The socket head enables driving where there is not sufficient space for wrenches or sockets.
Socket Cap Screws
Socket cap screws are most often found in machine parts, solar panel installations and automotive applications. In most applications where there is not sufficient space for wrenches or sockets, the socket head of a socket cap screw can still enable driving. Click here to buy socket cap screws online.
Button Head Socket Cap Screws
Button head socket cap screws have a domed head with a lower profile than the standard socket cap screw. These are generally used when a wider bearing surface or smoother appearance is needed, but do not offer the strength of standard socket cap screws and are best reserved for light fastening applications.
Flat Head Socket Cap Screws
Flat head socket cap screws offer many of the benefits of standard socket cap screws, with the addition of the flat head that can be countersunk into the substrate for a flush appearance.
Shoulder screws, also known as shoulder bolts, have a long, unthreaded, cylindrical shoulder that allows attached parts, like gears, pulleys, engine parts, mechanical assemblies and wheels to be rotated. As with standard socket cap screws, the socket head enables high torque fastening with limited clearance.
Half Dog Point Set Screws
Half dog point set screws have an extended tip that fits into a hole that has already been drilled into a shaft. These often replace dowels and can be used for frequent resetting and relocating.
Cone Point Set Screws
Cone point set screws feature a sharp conical-shaped point at the opposite end from the hex drive, and are used for permanent setting on soft or hardened shafts. Because this set screw style offers deep penetration, it creates the highest torsional & axial holding power of any set screws.
Cup Point Set Screws
Cup point set screws are generally used to secure one object within another. The knurled cup's serrated ridge reduces loosening from vibration even under the most severe vibrations, by combining digging action of the cup point with counter-clockwise ratchet-locking knurls.
A hex key, also known as an Allen key or Allen wrench, is a tool used to drive hex socket head bolts and screws. These tools are often used in kitted fastener packs where an end-user will be doing the screw tightening, as well as being a very common tool in the skateboarding industry.
Pipe plugs are used to close the ends and gauge pressure of internally threaded pipes and fittings, generally in water, sewer and plumbing applications.
