Value Collection R57600598 Shoulder Screw 5/8 in 18-8 Ss

Product Description

The VALUE COLLECTION R57600598 is a hex socket shoulder screw machined from 18-8 stainless steel with an uncoated finish. The shoulder measures 5/8 inches in diameter and 3/4 inches in length, providing a precision bearing surface for rotating or sliding components. The threaded portion is 1/2-13 UNC, and the head uses a 5/16-inch hex socket drive. This fastener is suited for mechanical assemblies where a fixed-diameter shaft or pivot point is required. Machinists, millwrights, and maintenance technicians are the typical installers.

Shoulder screws of this type are used in fixtures, jigs, linkages, and machinery where a hardened or precision-ground shaft shoulder acts as a bearing journal or spacer. The 18-8 stainless steel construction offers corrosion resistance suitable for moderate chemical and moisture exposure, making it appropriate for industrial equipment, food-processing fixtures, and similar applications where fastener corrosion is a concern.

Key Features

• Shoulder diameter of 5/8 inches provides a precise bearing surface for bushings and rotating components
• 3/4-inch shoulder length accommodates standard linkage and pivot designs
• 1/2-13 UNC thread standard for broad hardware compatibility
• 18-8 stainless steel construction for corrosion resistance in wet or chemical environments
• 5/16-inch hex socket drive for secure torque transfer with standard Allen keys or hex bits
• Uncoated finish maintains dimensional accuracy and allows for direct contact with mating parts

Compatibility

Designed as an OEM-style replacement or direct-use shoulder screw for mechanical assemblies, fixtures, and machinery requiring a 5/8-inch diameter shoulder with a 1/2-13 UNC threaded engagement.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 5/16-inch hex key or socket bit. Ensure mating bores and bushings are clean and sized appropriately for the 5/8-inch shoulder before installation. Do not apply thread-locking compounds to the shoulder surface, as this may interfere with the bearing function. Torque to the assembly specification required by the host equipment design.
