Value Collection 711054PS Shoulder Screw 5/16 in 1/4-20 Alloy Steel

Product Description

The VALUE COLLECTION 711054PS is a hex socket shoulder screw machined from 4140 alloy steel, designed for precision fastening applications where a smooth, close-tolerance shoulder is required for bearing, bushing, or pivot alignment. The shoulder measures 5/16 inch in diameter and 2-1/2 inches in length, providing a reliable locating surface. The threaded portion uses a 1/4-20 UNC thread form. The screw is left uncoated, preserving the base alloy steel finish. It is installed using a 5/32 inch hex socket driver. This type of fastener is commonly installed by machinists, mechanical assemblers, and maintenance technicians working on jigs, fixtures, and motion-control assemblies.

Shoulder screws of this type are used in light-to-medium industrial applications including fixture plates, tooling boards, pivot points, and guide systems. The 5/16 inch shoulder diameter is a standard size suited for bronze bushings, needle bearings, and similar bore-fit components. The uncoated 4140 alloy steel construction offers solid tensile strength for general mechanical assembly. This screw is sold individually with a minimum order quantity of 10 units, making it appropriate for production or maintenance stock replenishment.

Compatibility

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

Installation Notes

Installation is performed by machinists or maintenance technicians using a 5/32 inch hex key or T-handle driver. Ensure the mating bore is properly sized to the 0.3120 inch shoulder diameter for correct fit and alignment. De-energize or lock out any machinery before servicing assemblies that incorporate these screws. Do not use an impact driver on hex socket shoulder screws, as this can damage the socket recess or distort the shoulder.
