Frequently Asked Questions

Q: What sizes are available for these serrated flange hex socket screws?

A: These screws are available in M2, M3, M4, M5, M6, and M8 metric sizes, making them versatile for a wide range of fastening applications from small electronics to heavier mechanical assemblies.

Q: What is the benefit of the serrated flange on these Allen bolts?

A: The serrated flange acts as a built-in locking washer. Its serrations bite into the mating surface when tightened, distributing the clamping load and resisting loosening caused by vibration or dynamic loads — eliminating the need for a separate washer.

Q: Are these screws suitable for outdoor or corrosive environments?

A: Yes. Made from 304 grade stainless steel, these screws offer strong resistance to rust and corrosion, making them suitable for both indoor and many outdoor applications. For highly aggressive marine or chemical environments, a higher grade such as 316 stainless steel may be more appropriate.

Q: What tool do I need to drive these screws?

A: These screws require a standard hex key (Allen wrench) that matches the socket size of the screw. This drive style allows for high torque and a clean, recessed finish.
