BHCS - Button Head Cap Screw
The most common fastener head style purchased is the Button Head Cap Screw. We designed our own head specifications to create a button head with higher torque and resistance to Vice Grips®.
First, we cut the specified sidewall tolerance in half. This small adjustment created a large security barrier. Now Vice Grips® or wrenches can’t remove our button heads.
Second, we increased torque by enlarging our specified drive sizes. As a result, our button heads out torque TORX®.
