Value Collection R57600604 Shoulder Screw 5/8 in 18-8 Ss

Product Description

The VALUE COLLECTION R57600604 is an 18-8 stainless steel shoulder screw designed for applications that require a precise, hardened shoulder to serve as a shaft, pivot, or guide pin. The shoulder measures 5/8 inch in diameter and 1-1/2 inches in length, providing a controlled bearing surface between mating components. Drive engagement is via a 5/16 inch hex socket. The threaded section uses a 1/2-13 UNC thread form. This fastener ships uncoated and is suited for mechanical assemblies where corrosion resistance and dimensional accuracy are required. Machinists, maintenance technicians, and mechanical assemblers are the typical end users.

Shoulder screws of this type are used in jigs, fixtures, dies, linkages, and pivot assemblies across industrial, commercial, and light manufacturing environments. The 18-8 stainless steel construction makes this screw appropriate for environments with moderate moisture or chemical exposure. The 1/2-13 UNC thread allows engagement with standard tapped holes or hex nuts in steel, aluminum, or plastic assemblies. The uncoated finish is compatible with most standard installation setups without additional surface preparation.

Key Features

• Shoulder diameter of 5/8 inch (0.6250 inch) provides a precise bearing and locating surface
• Shoulder length of 1-1/2 inches accommodates standard fixture and linkage depths
• 18-8 stainless steel construction offers corrosion resistance in moderate-exposure environments
• 5/16 inch hex socket drive for use with standard hex keys or Allen drivers
• 1/2-13 UNC thread standard for compatibility with common tapped holes and hardware
• Uncoated finish requires no additional surface treatment prior to installation

Compatibility

Designed as a standard shoulder screw for use in mechanical assemblies requiring a 5/8 inch shoulder diameter and 1/2-13 UNC threaded engagement, including jigs, fixtures, pivot points, and guided linkage applications.

Installation Notes

Installation is performed by mechanical assemblers or maintenance technicians using a 5/16 inch hex key or Allen driver. Verify that the mating tapped hole conforms to 1/2-13 UNC specifications before installation. De-energize and lock out any equipment before servicing assemblies that contain this fastener. Avoid over-torquing, which can damage the threaded section or distort the mating component.
