Value Collection R63002920 Shoulder Screw 5/16in 1/4-20

Product Description

The VALUE COLLECTION R63002920 is a shoulder screw machined from 18-8 stainless steel, designed for precision fastening applications where a smooth, fixed-diameter shoulder is required. The shoulder measures 0.3125 inches (5/16 inch) in diameter and 1-1/2 inches in length, providing a precise pivot or spacer surface between mated components. The threaded portion is cut to 1/4-20 UNC standards. Drive engagement is via a 5/32-inch hex socket, requiring an Allen key or hex bit driver for installation and removal. This fastener is suited for mechanical assemblies, jigs, fixtures, and any application requiring a controlled-clearance shaft or pivot point.

Shoulder screws of this type are commonly installed in manufacturing equipment, precision mechanical assemblies, and light industrial fixtures. The 18-8 stainless steel construction provides corrosion resistance suitable for wet or mildly corrosive environments, making this screw appropriate for both indoor and outdoor use in trade and industrial settings. Mechanical technicians and maintenance professionals typically specify this screw where a turned, smooth-bore pivot, guide, or stripper bolt function is needed within a bolted assembly.

Key Features

• 5/16-inch (0.3125-inch) precision shoulder diameter for accurate fit in bored or reamed holes
• 1-1/2-inch shoulder length provides extended pivot or guide surface
• 1/4-20 UNC thread standard for broad hardware compatibility
• 5/32-inch hex socket drive for recessed or flush installation
• 18-8 stainless steel construction resists corrosion and oxidation
• Meets UNC thread standards for consistent thread engagement

Compatibility

Designed as a standard-dimension shoulder screw suitable for use in mechanical assemblies, fixtures, jigs, and equipment requiring a 5/16-inch shoulder diameter with 1/4-20 UNC threaded engagement.

Installation Notes

Install using a 5/32-inch hex key or hex socket bit driver. Ensure the mating bore diameter is matched to the shoulder diameter for proper fit and function. Do not overtighten the threaded section into the receiving material, as the shoulder — not the thread — is intended to bear the load or provide the pivot surface. De-energize or lock out any equipment before servicing assemblies that incorporate this fastener.
