Value Collection R63004023 Shoulder Screw 18-8 Ss 3/8-16

Product Description

The VALUE COLLECTION R63004023 is an 18-8 stainless steel shoulder screw designed for precision fastening applications where a smooth, accurately dimensioned shoulder serves as a bearing surface, pivot point, or alignment pin. The shoulder measures 0.5 inches in diameter and 1 inch in length, providing reliable contact surface geometry in assemblies requiring controlled movement or tight tolerances. The threaded section is 3/8-16 UNC, driven by a 0.25 inch hex socket. This fastener is installed by mechanical assemblers, millwrights, and maintenance technicians across a wide range of industrial and light manufacturing environments.

This shoulder screw is suited for use in jigs, fixtures, linkage assemblies, and pivot mechanisms where a hardened or polished shoulder engages a mating bore, bushing, or bearing. The 18-8 stainless steel construction makes it appropriate for moderately corrosive environments, including food-processing adjacent equipment, outdoor assemblies, and wet industrial settings. It is sold in minimum order quantities of 5 units per order, with 1 piece per package.

Key Features

• 0.5 inch shoulder diameter provides consistent contact surface for bearing and pivot applications
• 1 inch shoulder length suits standard fixture and linkage depth requirements
• 3/8-16 UNC thread ensures compatibility with standard tapped holes and hex nuts
• 18-8 stainless steel construction offers good corrosion resistance in moderate environments
• 0.25 inch hex socket drive for installation with standard Allen keys or hex bit drivers

Compatibility

Designed as a standard UNC shoulder screw for use in jigs, fixtures, pivot assemblies, and linkage mechanisms requiring a 0.5 inch shoulder diameter and 3/8-16 threaded engagement.

Installation Notes

Installation is performed by mechanical technicians using a 0.25 inch hex key or socket bit driver. Ensure the mating bore or bushing matches the 0.5 inch shoulder diameter before installation to maintain proper fit and function. Do not over-torque the threaded section, as this can distort the shoulder or damage the mating component. Follow applicable machinery safety lockout procedures before servicing any assembly containing this fastener.
