Shoulder Allen Bolts

Shoulder Allen Bolts, also known as Hex Socket Shoulder Screws, are precision fasteners designed for applications requiring accurate alignment, smooth rotation, and controlled spacing. These bolts feature a precision-machined unthreaded shoulder between the head and threaded portion, providing a bearing surface for moving parts.

Manufactured from high-quality alloy steel and heat-treated for superior strength and wear resistance, Shoulder Allen Bolts are widely used in machinery, tooling, dies, automation equipment, and mechanical assemblies where accuracy and durability are critical.
