Precision Brand 04030 Square Key Stock 12 in 6 Pack

Product Description

The PRECISION BRAND 04030 is a square key stock used to secure rotating components such as gears, pulleys, and sprockets to shafts in mechanical power-transmission assemblies. Manufactured from low-carbon steel with a gold dichromate finish that provides corrosion resistance, each piece measures 12 inches in length with an 8 mm by 8 mm cross-section conforming to DIN 6880. This pack contains 6 pieces, making it a practical supply for maintenance shops, millwrights, and industrial technicians who work on drive systems requiring standard metric square keyways.

Square key stock is used across a wide range of mechanical and industrial applications including conveyor drives, pump shafts, fan assemblies, and gearbox output shafts. The 8 mm square profile fits standard metric keyways where precise torque transmission and positive shaft-to-hub alignment are required. This stock is suitable for both light-duty and moderate-load applications in commercial and industrial settings. Technicians cut individual keys to length from the 12-inch stock pieces as needed to match specific shaft and hub configurations.

Installation Notes

Installation is typically performed by millwrights or mechanical maintenance technicians. Cut key stock to the required length using a hacksaw or cold saw and deburr all cut edges before fitting. Ensure the shaft and hub keyways are clean and free of damage before installation. Follow equipment manufacturer specifications for fit tolerance and any required retaining compounds.
