Description: Except for differences in reference standards, metric button head screws are identical in function. Designed to be paired with matching Torx/hex wrenches, they efficiently transfer torque directly into the screw during tightening to prevent drive strip-out. Featuring fully threaded shanks, they are widely used on the exposed exterior surfaces of machine tools, mechanical equipment, furniture, bicycles, and automotive products.
