Value Collection 711062PS Shoulder Screw 5/16 in 4140 Alloy Steel

Product Description

The VALUE COLLECTION 711062PS is a hex socket shoulder screw machined from 4140 alloy steel in an uncoated finish. The shoulder measures 5/16 inches in diameter and 3 inches in length, providing a precise bearing surface for rotating or sliding components in mechanical assemblies. The threaded portion is 1/4-20 UNC. Drive is a 5/32 inch hex socket. This fastener is installed by machinists, maintenance technicians, and mechanical assemblers wherever a hardened, close-tolerance shoulder is required to locate parts or serve as a pivot or guide pin.

Shoulder screws of this type are commonly used in jigs, fixtures, dies, and precision mechanical assemblies across industrial and commercial applications. The 4140 alloy steel construction provides the strength and wear resistance needed in high-cycle or load-bearing pivot and guide applications. The 7/16 inch head diameter and 7/32 inch head height suit standard counterbored socket clearances. This screw is sold individually with a minimum order quantity of 10 units.

Key Features

Compatibility

Designed as a standard ANSI B18.3 shoulder screw for use in mechanical assemblies, jigs, fixtures, and dies requiring a 5/16 inch diameter shoulder, 3 inch shoulder length, and 1/4-20 UNC threaded end.

Installation Notes

Installation is performed by machinists or mechanical technicians using a 5/32 inch hex key or Allen-style driver. The mating tapped hole should be sized for 1/4-20 UNC thread engagement. De-energize, lock out, and tag out any equipment before installing or replacing shoulder screws in live machinery. Do not overtighten; thread engagement depth should follow standard fastener torque practices for 1/4-20 alloy steel fasteners per applicable industry guidelines.
