Allen Button Head BHCS

The Socket Button Head Screw design as per ISO 7380-1 is primarily used where a lower profile head is required and for aesthetical reasons.

Button head socket cap screws combine the similar shape of a pan head with the driver of a socket head. The socket driver is ideal for low clearance applications that require a large area clamping face.

Compared to a standard socket head cap screw, button heads have a lower and wider profile which can be useful when the clamping material is too thin to counter-bore.

A button head socket cap screw’s large diameter face also helps to distribute force more evenly. They are also known as Button Head Cap Screws or BHCS.

These screws can take a lower tightening torque as compared to the DIN 912 screws.

Hence, these screws are not recommended for high demand applications.

Available in Hexagonal Socket drive and 6-Lobe (Hexalobular) drive for higher reliability.
