Value Collection -40822-1 Shoulder Screw 5/8 in 4140 Steel

Product Description

The VALUE COLLECTION -40822-1 is a shoulder screw machined from 4140 alloy steel, designed for precision fastening applications where a controlled-diameter shoulder is required for alignment, pivoting, or bearing retention. The shoulder measures 0.625 inches in diameter and 0.75 inches in length, providing a close-tolerance shank for guiding mating components. Drive engagement is via a 5/16 inch hex socket, and the thread is 1/2-13 UNC. The uncoated finish suits dry or lightly oiled environments. This screw is installed by machinists, maintenance technicians, and fabricators working on jigs, fixtures, dies, and mechanical assemblies.

This shoulder screw is suited for use in industrial machinery, tooling fixtures, hinged mechanisms, and assemblies requiring a precision pivot or linear guide point. The 4140 alloy steel construction provides good tensile strength and wear resistance for demanding mechanical environments. Each package contains 25 pieces, making it practical for production line maintenance or shop stock replenishment. It is sold with a minimum order quantity of 1 package.

Compatibility

Designed as a standard shoulder screw for industrial fixtures, jigs, dies, and mechanical assemblies requiring a 0.625 inch shoulder diameter and 1/2-13 UNC threaded engagement.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 5/16 inch hex key or socket driver. Ensure the mating bore or bushing is dimensioned to accept a 0.625 inch shoulder before installation. Disengage all energy sources and de-energize or lock out the machine before servicing any fastened assembly. Do not use impact tools that may damage the hex socket recess.
