Conquest Fasteners Coarse Socket Shoulder Screws are engineered for precision alignment, smooth rotation, and dependable fastening in demanding applications. Commonly referred to as shoulder bolts or shoulder cap screws, these fasteners feature a precision-ground shoulder that acts as a shaft, making them ideal for use in moving assemblies, pivots, and mechanical linkages.

Manufactured from high-strength alloy steel, these shoulder screws deliver excellent durability and wear resistance in industrial environments. The socket head design paired with a 1/8" hex drive allows for secure installation with consistent torque, while the coarse thread ensures strong engagement in a variety of materials. Built to meet IFI and ASME B18.3 specifications, these precision shoulder bolts provide the consistency and reliability professionals expect.

Available in a range of sizes and configurations, including common options like 1/4 shoulder bolt and other imperial shoulder bolts, these fasteners are suited for everything from light-duty assemblies to heavy-duty industrial applications. Whether you need small shoulder screws for compact designs or hardened shoulder bolts for demanding environments, Conquest delivers dependable performance across the board.
