Key Features
- Black oxide coating helps reduce friction and provides mild corrosion resistance
- Alloy steel is one of the strongest materials used in fasteners, making this an ideal material to use when the primary concern is the application pulling apart
- Socket cap head offers high holding power
- Drive system is a hexagon-shaped hole
Product Description
Socket cap screws, also known as Allen head screws, have a recessed drive and are commonly used when there is not enough clearance for a conventional wrench or socket. They are durable and used in many industrial applications.
The black oxide coating provides some lubricity to the product, meaning that there is less friction generated when using these products. The coating also provides a mild corrosion resistance but should not be relied on in environments where corrosion resistance is a primary concern. Alloy steel is steel that has been alloyed with other materials to improve overall physical properties. Steels are designated by a four-number SAE Steel grade. The first two digits indicate the primary materials used to form the steel. The last two digits identify the percentage of carbon for the alloy (in hundredths). Tensile strength ranges for the alloys typically used in these fasteners range from 170,000 to 180,000 psi (pounds per square inch), making these amongst the strongest of materials.
With a high cylindrical head, socket cap head fasteners offer high holding power at high torque levels. Hex socket drive systems are driven by hex wrenches or power tools with hexagonal bits.
A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine.
