Bryce Fastener Altered Standard Fastener Head Styles for Better Functionality and Security

Button, Flat, and Socket head styles are available in all diameters and drives we manufacture.

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 head drives out torque TORX®.

FHCS - Flat Head Cap Screws

Our Flat Head Cap Screws have the same high torque capability and they also out torque TORX®.  We follow the standard flat head specifications. It’s vital our flat head security screws are not sitting above a surface where wrenches can remove them.

SHCS - Socket Head Cap Screw

When Mr. Allen originally developed the Socket Head Cap Screw, he could not keep the Allen wrench from stripping, unless he made the head extremely high. We changed the old SHCS specification because it’s counterproductive for our high torque drive systems. The extra glob of material takes extra tonnage to forge, and breaks tooling. To lower costs, we specify our Socket Head Cap Screws at 2/3 head height. They torque higher than Allen (even with a center rejection pin) and can use a shallower counterbore.
