We supply high-quality Shoulder Cap Screws designed for applications requiring a precision-machined shoulder that acts as a shaft or pivot, providing smooth and accurate rotation or sliding. These screws feature a cylindrical shoulder with a larger diameter than the threaded portion, combined with a hexagonal socket head for easy installation. Manufactured from alloy steel or stainless steel, Shoulder Cap Screws offer excellent strength, corrosion resistance, and durability, making them ideal for machinery, automotive, robotics, and precision engineering applications. Key Features Type: Shoulder Cap Screw (Precision Shoulder with Hex Socket Head) Material Options: Alloy Steel (Grades 8.8 / 10.9), Stainless Steel (SS 304 / SS 316) Standards: DIN 912 / ISO Equivalent Finish Options: Black Oxide, Zinc Plated, Plain, Natural Stainless Steel Finish Properties: Precision-machined shoulder, high tensile strength, corrosion-resistant, vibration-resistant, smooth bearing surface Surface: Threaded shank with precision shoulder and hex socket head for secure torque application Applications: Machinery, automotive, robotics, conveyors, precision instruments, industrial assemblies

A Shoulder Screw, also known as a shoulder bolt, is a precision fastener distinguished by its unthreaded shoulder section between the head and the threaded shaft. Designed to function as a pivot point, shaft, guide, or bearing surface, shoulder screws are essential in applications requiring accurate alignment, rotation, or sliding movement
