Precision Brand 04000 Square Key Stock 12 in 6 Piece

Product Description

The PRECISION BRAND 04000 is a square key stock set used to secure rotating components such as gears, pulleys, and sprockets to shafts in mechanical power transmission assemblies. Manufactured from low-carbon steel to DIN 6880 material specification, each piece measures 12 inches in length with a 2.0 mm square cross-section and a plain finish. This package contains 6 pieces, giving technicians and machinists a ready supply for multiple applications or custom-cut fitment on the job. The plain finish is suitable for most indoor mechanical environments where additional corrosion protection is applied separately.

Square key stock of this profile is commonly used in light-duty to medium-duty machinery, including conveyor drives, pump assemblies, and general industrial equipment. Maintenance technicians, millwrights, and mechanical contractors use this stock when replacing worn keys or fitting new drive components during equipment overhaul. The 2.0 mm square profile fits standard keyways machined to DIN 6880 tolerances, making it appropriate for metric-dimensioned shafting found in imported or OEM-specified equipment.

Key Features

• Square profile at 2.0 mm x 2.0 mm cross-section for metric keyway fitment
• 12-inch length allows field cutting to required dimensions
• Low-carbon steel construction per DIN 6880 material specification
• Plain finish — ready for installation or secondary coating as needed
• 6 pieces per package for multi-use or backup stock on the job

Compatibility

Designed as a standard replacement key stock for mechanical assemblies using 2.0 mm square keyways machined to DIN 6880 specification. Verify shaft and hub keyway dimensions before installation.

Installation Notes

Key stock installation is typically performed by millwrights or mechanical maintenance technicians. Disengage and lockout all power to the drive system before removing or installing any shaft components. Key stock should be cut to length using appropriate metal-cutting tools and deburred before fitting into the keyway. Do not force an oversized key into a keyway, as this can damage the shaft or hub bore.
