Value Collection R57600686 Shoulder Screw 18-8 Ss

Product Description

The VALUE COLLECTION R57600686 is a hex socket shoulder screw machined from 18-8 stainless steel with an uncoated finish. The shoulder measures 1 inch in diameter and 2 inches in length, providing a precision bearing surface for pivot points, linkages, and guided assemblies. The threaded end is 3/4-10 UNC. A 1/2-inch hex socket drive and a low-profile head make installation straightforward in close-clearance applications. Machinists, maintenance technicians, and assembly workers use this fastener where a smooth, accurately sized shaft section is required alongside a threaded clamping end. The 18-8 stainless construction resists corrosion in moderate-exposure environments.

Shoulder screws of this style are used across industrial machinery, jigs and fixtures, conveyor systems, and mechanical assemblies that require a rotating or sliding fit. The 1-inch shoulder diameter and 2-inch shoulder length suit medium-duty pivot and guide applications. The 3/4-10 UNC thread is a coarse-pitch standard thread widely used in general industrial fastening. This screw is sold individually and is appropriate for both OEM builds and MRO replacement applications where a precise shoulder diameter is critical to fit and function.

Key Features

• 1-inch shoulder diameter with a 2-inch shoulder length for accurate bearing and pivot fits
• 3/4-10 UNC coarse-pitch thread for broad compatibility with standard tapped holes
• 18-8 stainless steel construction provides corrosion resistance without plating
• Uncoated finish maintains dimensional accuracy on the shoulder surface
• 1/2-inch hex socket drive for use with standard Allen keys or socket drivers
• Head diameter of 1-5/16 inches and head height of 5/8 inch for a secure clamping face

Compatibility

Designed as a standard shoulder screw for use in industrial machinery, fixtures, and mechanical assemblies requiring a 1-inch shoulder diameter, 2-inch shoulder length, and 3/4-10 UNC thread.

Installation Notes

Installation is performed with a 1/2-inch hex key or socket driver. Ensure the mating tapped hole is clean and meets 3/4-10 UNC thread specifications before driving the screw. Torque the fastener to the value specified by the equipment manufacturer or the applicable engineering standard for the joint. Avoid over-tightening, which can distort the shoulder or damage the mating bore.
