Value Collection MP31963 Woodruff Key Steel Pack of 5

Product Description

The VALUE COLLECTION MP31963 is a No. 1008 standard Woodruff key designed for securing rotating components to shafts in mechanical assemblies. Woodruff keys provide a semi-circular, positive drive connection between a shaft and a hub, pulley, or gear, preventing relative rotation under load. This key measures 1 inch long by 5/16 inch wide and is machined from steel for strength and dimensional accuracy. Each pack contains 5 keys. Machinists, millwrights, and maintenance technicians typically install these during equipment assembly or repair across a broad range of industrial and commercial machinery applications.

No. 1008 Woodruff keys are commonly used in pump shafts, motor shafts, gear reducers, and general power transmission equipment. The standard sizing follows established dimensional standards for Woodruff keyways, making these suitable for use in both new assembly and replacement service on equipment specifying a No. 1008 key. These are appropriate for residential and commercial mechanical repair scenarios wherever a standard Woodruff keyway is machined into the shaft and mating component.

Compatibility

Designed as a standard No. 1008 Woodruff key replacement for any shaft assembly with a matching Woodruff keyway machined to the No. 1008 dimensional specification.

Installation Notes

Woodruff keys are installed by machinists, millwrights, or maintenance technicians. Always de-energize and lock out the equipment before beginning shaft disassembly. Ensure the keyway slot on both the shaft and mating hub are clean and free of burrs before seating the key. Do not force an oversized key into a keyway, as this can damage the shaft or hub.
