What is hexagon socket head cap screw?
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 is a hex socket screw?
Hexagon socket head cap screws (cap bolts) Bolts with a hexagonal hole on a cylindrical head that’s fastened with a hex wrench. Although they are also called cap screws or socket screws, the most common names are “hexagon socket head cap screw” and “cap bolt”. They are generally given black oxide finish.
What size are hex head screws?
American National Standard and Unified Standard Heavy Hex Screws and Hex-cap Screws ANSI/ASME B18. 2.1-1996, specify the screws ideal size range is 0.25–3 in (6.35–76.20 mm) in diameter.
When would you use a socket head cap screw?
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. Wood screws have a threaded shaft and are used to attach wood to wood. These screws can have a few different times of thread.
What do cap screws look like?
Cap screws have a large head and a cylindrical shaft with external threads. The head has a larger diameter than the threaded portion, this provides a positive mechanical stop when tightening the screw. Cap screws are tightened directly into a threaded or tapped hole, usually without a nut.
What is a cap allen screw?
Standard socket head cap screws (allen cap screws) possess a cylindrical head with a flat, chamfered top surface and a recessed socket drive. The outer sides of the cylindrical cap are commonly knurled.
What are hex cap screws used for?
Generally speaking, hex cap screws are used in precise applications like an OEM setting where tight tolerances are required. Hex bolts are often specified when the mechanical properties are more important than dimensional tolerances, like the construction industry.
When would you use a hex screw?
Hex bolts can be used for infrastructure that requires a strong fastener with high tensile strength properties due to their design and base materials. As mentioned, they can also be used in tight spaces with limited access because tools can access them from all angles due to the six points of contact on the hex head.
What is a socket head screw used for?
Socket head cap screws are widely used in industrial production and assembly lines, including in the automotive sector, furniture manufacture, machine tooling applications and steel fabrication.
What steel are socket head cap screws made of?
Socket Head Cap Screws are heavy duty screws made from DFARS sourced alloy steel. Manufactured in the USA by Parker Fasteners, these strong externally threaded screws offer the highest strength for commercial fasteners, and are the ideal fastener where there is not sufficient space for wrenches or sockets.
