Step Bolts Shoulder Flat Hexagon Socket Black Plating Custom Made

Step bolts also known as shoulder bolts. Shoulder bolt is a screw with an unthreaded shoulder that is larger in diameter than the threads. The cylindrical shoulder that allows for the rotation of attached parts like pulleys, gears, moving parts of engines and mechanical assemblies, and rolling wheels. Step bolts also used to attach stripper plates. The socket head enables high torque fastening with limited clearance. Ever Hardware provides custom-made fasteners and customizable packaging.

The hex socket screw drive has a hexagonal recess and may be driven by a hex wrench, also known as an Allen wrench, Allen key, hex key, or inbus as well as by a hex screwdriver (also known as a hex driver) orbit. Tamper-resistant versions with a pin in the recess are available.

Zinc coatings prevent oxidation of the step bolts by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not cause a breakdown of the substrate’s surface integrity as it is formed. Indeed, the zinc oxide, if undisturbed, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers. The majority of hardware parts are zinc-plated, rather than cadmium-plated.
