Value Collection R57600608 Shoulder Screw 5/8 in 18-8 Ss

Product Description

The VALUE COLLECTION R57600608 is an 18-8 stainless steel shoulder screw designed for precision fastening applications where a smooth, controlled shoulder is required to serve as a locating pin, pivot point, or shaft for rotating or sliding components. The shoulder measures 0.625 inches in diameter and 2 inches in length, providing an accurate bearing surface. The threaded end is 1/2-13 UNC, driven by a 5/16-inch hex socket. The uncoated finish preserves the natural corrosion resistance of 18-8 stainless steel, making this screw suitable for wet, chemical-exposure, or outdoor environments.

Shoulder screws of this type are commonly used in machine shops, assembly fixtures, jigs, dies, and mechanical linkages across manufacturing and industrial maintenance settings. The 5/8-inch shoulder diameter and 2-inch shoulder length suit applications requiring a close-tolerance bearing surface in a mid-size fastener. Licensed tradespeople and industrial maintenance technicians working with mechanical assemblies, conveyor systems, or tooling fixtures will find this screw a direct-fit fastener solution. No specific OEM compatibility data was provided with this part.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and chemical environments
• Precision 0.625-inch shoulder diameter serves as an accurate locating or pivot surface
• 2-inch shoulder length accommodates moderate-depth bearing or guide applications
• 1/2-13 UNC thread standard ensures wide compatibility with standard tapped holes
• 5/16-inch hex socket drive allows use of standard Allen keys and hex bit drivers
• Uncoated finish maintains dimensional accuracy and natural stainless corrosion resistance

Compatibility

Designed as a standard shoulder screw for use in mechanical assemblies, fixtures, jigs, and linkages requiring a 5/8-inch diameter shoulder, 2-inch shoulder length, and 1/2-13 UNC threaded end.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a 5/16-inch hex key or socket driver. Ensure the mating tapped hole is clean and correctly threaded to 1/2-13 UNC before installation. De-energize or lock out any machinery before replacing shoulder screws in live assemblies. Avoid over-torquing, as stainless steel fasteners are susceptible to galling; applying an appropriate anti-seize compound to the threads is standard practice.
