Specification of Allen Bolt:

Allen bolts are widely used in various applications, including machinery, automotive, electronics, furniture assembly, and many others. They are favored for their ease of use, precise torque application, and the fact that they don’t protrude significantly when installed, making them suitable for situations where a flush or low-profile appearance is desired.

The Allen wrench or hex key used with Allen bolts comes in various sizes to match the socket size of the bolt. Allen bolts are commonly available in metric and imperial (inch) sizes, and their selection should match the specific requirements of the project or equipment being assembled.
