Fastenal

Wave washers, also called spring washers, feature a lobed design suitable for low strength fastening, irregular surfaces, and variations in tolerance.

Hex cap screws feature a washer face under the head and a chamfered point, whereas a hex bolt does not have a washer face or chamfered threads. They are made of low-carbon steel and are very common in construction or repair projects.

Weld nuts are made with a greater amount of material than other nuts so that the nut’s form is maintained after being welded to another object.

Socket cap screws are commonly used in machine parts, die fixturing, and clamping. The socket head enables driving where there is not sufficient space for wrenches or sockets.

These general use flat washers are positioned under the head of a bolt or nut in order to provide a smooth bearing surface and distribute the fastener load over a wider area.

Machine screws have a uniform diameter the entire length of the shaft as opposed to tapered screws which have a pointed tip. They are used to fasten machine components, appliances and more.
