Value Collection R57600614 Shoulder Screw 5/8 in 18-8 Ss

Product Description

The VALUE COLLECTION R57600614 is an 18-8 stainless steel shoulder screw designed for precision fastening applications where a smooth, hardened shoulder is required as a pivot, guide, or spacer element. The screw features a 5/8-inch shoulder diameter and a 2-3/4-inch shoulder length, providing a consistent bearing surface for bushings, linkages, or moving components. The threaded portion is 1/2-13 UNC, and the head is driven with a 5/16-inch hex socket key. The uncoated 18-8 stainless steel construction offers good corrosion resistance in moderate service environments. This type of fastener is installed by machinists, maintenance technicians, and mechanical assemblers across a wide range of industrial and mechanical applications.

Shoulder screws of this type are commonly used in jigs, fixtures, dies, and mechanical assemblies where a precise cylindrical surface is needed to locate or retain a component. The smooth shoulder acts as a shaft, axle, or guide pin, while the threaded end clamps the assembly together. This screw is suited for use in light industrial machinery, conveyor systems, linkage assemblies, and tooling fixtures where repeatable alignment and low-friction pivot points are required. The 18-8 stainless steel material makes it appropriate for environments with mild moisture exposure or where iron contamination must be avoided.

Key Features

• 5/8-inch shoulder diameter with a 2-3/4-inch shoulder length for a generous bearing surface
• 1/2-13 UNC thread for secure clamping engagement
• 5/16-inch hex socket drive for installation with a standard Allen or hex key
• 7/8-inch head diameter and 3/8-inch head height for low-profile seating
• 18-8 stainless steel construction provides corrosion resistance without a coating
• Uncoated finish maintains dimensional accuracy on the shoulder surface

Compatibility

Designed as a standard shoulder screw for use in jigs, fixtures, tooling, and mechanical assemblies requiring a 5/8-inch diameter shoulder pivot or guide post with a 1/2-13 UNC threaded shank.

Installation Notes

Install using a 5/16-inch hex key or Allen driver. Ensure the mating bore is sized appropriately for the 5/8-inch shoulder to achieve the intended fit class. De-energize or lock out any machinery before replacing or installing shoulder screws in moving assemblies. Avoid overtightening, as excessive torque can damage the threaded hole or distort the assembly.
