Top Questions And Answers For Socket Head And Machine Bolts

Where are socket bolts used?

Socket head cap screws are commonly chosen for applications involving machine parts, die fixtures, and clamping. Their usefulness also extends to jobs involving equipment fastening, wood construction, and various metal part connections. Because they are tightened or loosened with an Allen key, they excel as a fastener in tight spaces.

What tools are used with socket head bolts?

Socket head bolts can be tightened or loosened with either a socket wrench or an Allen key. The socket wrench grips the exterior of the bolt's grooved head. An Allen key, or hex wrench, inserts in the recessed, hexagonal drive. Although socket wrenches may be used, installation and adjustments are normally done with the Allen key.

What is a socket head bolt?

Socket head bolts get their name from the recessed, hexagonal socket in their cylindrical heads. These fully threaded fasteners are made to connect machine parts and some structural elements. An Allen wrench fitted into the recessed head is used to tighten or loosen the bolts. Nuts are threaded on the end to complete installation.

What is a socket bolt?

Socket bolts or socket screws are threaded fasteners designed to be installed with nuts. They are suitable in numerous machine and structural situations. Their cylindrical heads have hexagonal, recessed sockets that are turned with an Allen key or hex wrench. Upon installation, socket bolt heads are flush against the installation surface.

What do socket bolts look like?

Sockets bolts have recessed sockets in their cylindrical-shaped heads. The socket drive typically has a hexagonal shape. Ridges on the outer rim of the head are common as well. The width of the head will be slightly wider than the bolt's shaft. Beneath the head, a fully threaded shaft extends to a blunt end.

What are socket head screws made from?

Tough industrial metals used in the making of socket head cap screws can resist corrosion. Stainless steel screws possesses automatic corrosion resistance. Socket head cap screws made from carbon steel require a black oxide treatment to form a resistant finish. Socket head cap screws may also be made from rigid polymers like nylon.

What are socket bolt dimensions?

Dimensions for socket bolts describe the height and diameter of the head and the length and diameter of the threaded shaft. Standard proportions for socket bolts result in a head diameter 1.5 times greater than the shaft's diameter. The head's height should have the same measurement as the shaft's diameter.

How are socket machine bolts measured?

Like other types of bolts, socket machine bolts are measured according to length and diameter of the threaded shank. Shank length represents the measurement from the base of the head to the end of the shank. The shank diameter includes the threads, and this measurement is typically the same as the height of the bolt's head.

How are socket head cap screws made?

Socket head caps screws differ somewhat from conventional bolts and screws. During manufacturing, their heads are altered with a die stamp that creates a head socket and a ridged rim that forms a grip. Some socket head caps screws are then enhanced with a coating that builds a resistant finish.

How are socket bolts installed?

Socket bolts have heads with outer ridges and an inner recessed drive. A socket wrench turns the bolt by gripping the outer ridges. An Allen key turns the bolt through the recessed drive. Socket head screws share these characteristics with socket bolts. A nut is needed to finish installation of a socket bolt.
