Value Collection R57600652 Shoulder Screw 3/4 in 18-8 Ss

Product Description

The VALUE COLLECTION R57600652 is a hex socket shoulder screw machined from 18-8 stainless steel with an uncoated finish. The shoulder measures 0.75 inches in diameter and 2.25 inches in length, providing a precise bearing surface for rotating or sliding components such as linkages, pivots, and pulleys. The threaded portion uses a 5/8-11 UNC thread standard for secure fastening into tapped holes. A 3/8-inch hex socket drive and a 1-inch diameter head with a 0.5-inch head height allow installation with standard Allen keys or hex bit drivers. The part weighs 0.6 pounds. Machinists, maintenance technicians, and industrial assembly professionals are the typical installers.

Shoulder screws of this configuration are used in mechanical assemblies where a smooth, hardened shaft is needed to guide, align, or support a moving part. Common applications include jig and fixture construction, die sets, machine tooling, conveyor components, and industrial equipment maintenance. The 18-8 stainless steel construction provides moderate corrosion resistance, making this screw suitable for washdown environments, food processing equipment, and outdoor machinery where mild to moderate moisture exposure is expected.

Key Features

• 0.75-inch shoulder diameter and 2.25-inch shoulder length provide a precision bearing surface
• 18-8 stainless steel construction offers corrosion resistance in wet or mildly corrosive environments
• 5/8-11 UNC threaded section for reliable engagement in standard tapped holes
• 3/8-inch hex socket drive compatible with standard Allen keys and hex bit drivers
• 1-inch head diameter with 0.5-inch head height for positive seating and controlled clamp load
• Uncoated finish maintains dimensional accuracy and avoids coating buildup in precision fits

Compatibility

Designed as a standard-dimension shoulder screw suitable for jigs, fixtures, dies, and general industrial mechanical assemblies requiring a 0.75-inch shoulder diameter with 5/8-11 UNC threading.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 3/8-inch hex key or hex bit driver. Ensure the receiving tapped hole meets 5/8-11 UNC thread specifications and that the hole depth is sufficient for full thread engagement before installing. Do not overtorque; consult applicable fastener torque guidelines for 18-8 stainless steel to avoid galling, which is common with stainless fasteners. Apply an anti-seize compound to the threads if repeated removal is anticipated.
