Value Collection R63004644 Shoulder Screw 18-8 Ss Hex Socket

Product Description

The VALUE COLLECTION R63004644 is a stainless steel shoulder screw designed for precision fastening applications that require a smooth, accurately dimensioned shank. The shoulder measures 0.5 inches in diameter and 1.5 inches in length, providing a reliable pivot or bearing surface in mechanical assemblies. The threaded portion is 3/8-16 UNC, driven by a 1/4-inch hex socket drive. Constructed from 18-8 stainless steel, this fastener offers solid corrosion resistance and is suited for environments where mild chemical exposure or moisture is a factor. Machinists, maintenance mechanics, and fabricators typically specify shoulder screws when a precision shaft or pivot point is needed within a component assembly.

This shoulder screw is commonly used in jigs, fixtures, dies, and mechanical linkages where a controlled-clearance shaft is required. The smooth shoulder acts as a guide pin or pivot, allowing mating components to rotate or slide against the shank rather than the threads. It is appropriate for both light industrial and general mechanical applications where dimensional consistency and corrosion resistance are priorities. The 18-8 stainless steel construction makes it a practical choice in food service equipment, instrumentation, and outdoor or humid environments.

Key Features

• 0.5-inch shoulder diameter provides a precise bearing or pivot surface
• 1.5-inch shoulder length suits medium-depth assemblies and linkage applications
• 3/8-16 UNC thread for reliable clamping with standard hardware
• 1/4-inch hex socket drive for torque application with standard Allen keys or hex bits
• 18-8 stainless steel construction resists corrosion in humid or mildly corrosive environments

Compatibility

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

Installation Notes

Shoulder screws are typically installed by maintenance mechanics or machinists using a hex key or socket bit sized to the 1/4-inch drive. Always ensure the mating bore diameter matches the shoulder diameter closely to achieve the intended fit. Do not apply thread-locking compounds to the shoulder itself. Power down and de-energize any equipment before servicing assemblies that incorporate shoulder screws as pivot or guide pins.
