Value Collection R57600602 Shoulder Screw 5/8 in 18-8 Ss

Product Description

The VALUE COLLECTION R57600602 is a hex socket shoulder screw machined from 18-8 stainless steel with an uncoated finish. The shoulder measures 0.625 inches in diameter and 1.25 inches in length, providing a precise bearing surface for pivoting or sliding components. The 1/2-13 UNC threaded section draws the screw securely into tapped holes. The 7/8-inch diameter head accepts a 5/16-inch hex socket driver. This fastener is installed by machinists, maintenance technicians, and assembly professionals wherever a controlled-tolerance shaft surface is required between moving parts.

Shoulder screws of this type are used in tooling fixtures, jigs, die sets, linkage assemblies, and mechanical subassemblies across industrial and light manufacturing environments. The stainless steel construction makes this screw suitable for applications where mild corrosion resistance is needed alongside dimensional precision. A single-piece quantity is available, making it practical for repair and replacement work as well as prototype and low-volume production builds.

Key Features

• 0.625-inch precision shoulder diameter provides a controlled bearing or pivot surface
• 1.25-inch shoulder length suits standard fixture and linkage depth requirements
• 18-8 stainless steel construction offers good corrosion resistance and mechanical strength
• 1/2-13 UNC thread standard ensures broad compatibility with standard tapped holes
• 5/16-inch hex socket drive allows torque application with standard allen keys or socket drivers
• Uncoated finish maintains dimensional integrity without added plating thickness

Compatibility

Designed as a standard shoulder screw for use in any application requiring a 5/8-inch shoulder diameter, 1-1/4-inch shoulder length, and 1/2-13 UNC thread in 18-8 stainless steel construction.

Installation Notes

Shoulder screws are installed by maintenance technicians and machinists using a 5/16-inch hex key or socket driver. Always ensure the receiving tapped hole depth and thread engagement meet accepted fastener engineering guidelines before final torque. Clean threads and mating surfaces before installation to prevent galling, which is a known risk with stainless steel fasteners. Do not use impact drivers on shoulder screws, as over-torque can damage the precision shoulder surface.
