Value Collection 31952 Woodruff Key Steel 50 Pack

Product Description

The VALUE COLLECTION 31952 is a No. 505 standard Woodruff key designed for securing rotating components to shafts in mechanical assemblies. Woodruff keys provide a reliable, semi-circular keyway fit that resists rotational slippage between a shaft and hub. This key measures 5/8 inches in length and 5/32 inches in width and is manufactured from steel for durability under load. Sold in a pack of 50, this listing is appropriate for shops, maintenance teams, and trade professionals who require ready inventory of common fastening hardware.

No. 505 Woodruff keys are used across a wide range of mechanical and light industrial applications, including HVAC blower assemblies, pump shafts, compressor drives, and general power-transmission equipment. They are suited for both original equipment assembly and field-replacement scenarios where a worn or damaged key must be swapped during service. The pack quantity of 50 makes this a practical choice for maintenance operations that service multiple units regularly.

Installation Notes

Woodruff keys are typically installed by machinists, millwrights, or trained HVAC and mechanical service technicians. Always de-energize and lock out the equipment before removing or installing any shaft hardware. Inspect the keyway on both the shaft and hub for wear or damage before seating the new key. Do not force an oversized key into a keyway, as this can cause keyway distortion or shaft damage.
