What is hexagon socket head cap screw?

Hexagon head cap screws, also called hex bolts or hex head cap screws, are threaded fasteners with a six-sided head. They are installed with a wrench or a socket. Compared to other fasteners, hex head cap screws provide a larger surface-bearing area for better clamping.

What is a socket head bolt?

A socket head cap screw, also known as a socket cap screw, socket screw, or Allen socket bolt, is a type of cap screw with a cylindrical head and hexagonal drive hole. Typically driven with allen wrenches or hex keys, they also come in Button head and Flat head variants.

What are socket head bolts used for?

Socket head cap screws are a special type of fastener. Socket head cap screws are typically used in machine parts, die fixturing, and clamping. Socket head cap screws are ideal for applications in which there is not enough space to maneuver wrenches or sockets.

What is a hexagon screw?

Hex bolts, or hex cap screws, are large bolts with a six-sided head (hexagonal!) used to fasten wood to wood, or metal to wood.

What does a socket head cap screw look like?

A socket cap screws are machine screws with a cylindrical barrel shaped head containing a hexagonal socket. The head has a smaller diameter than most other machine screw heads, typically just 1.5 times the nominal thread diameter.

What grade are socket head bolts?

Typical bolts are supplied as grade 5.8, 8.8, or 10.9. Socket cap screws are often available in grade 12.9, meaning it has a UTS of 1200 MPa and will yield at 90% of this (1080 MPa).

What grade are black socket head bolts?

Grade 5 is the most common grade used in manufacturing assembly.

What material are socket head cap screws made of?

alloy steel
It is made of stainless steel, carbon steel or alloy steel making it corrosion resistant. An internal hex drive is usually used for its installation on surfaces. The clamped parts get their support from stretching the screws to handle the external forces faced by it.

What is a hexagonal head?

The “hex head” term typically refers to a machine screw with a preformed machine thread. Machine screws resemble bolts but with a threaded shaft. Less commonly, wood and self-tapping screws have a hex head, which is helpful when high torque is required.

What bolts have hexagonal heads?

Hex bolts, also called hexagon screw head bolts, hex cap bolts, hex-cap screws, or machine bolts, are a very common choice when it comes to construction and repair. Hexagon screw head bolts come in a large variety of sizes and diameters.
