Precision Brand 14525 Square Keystock Zinc Plated 12 in 2pk

Product Description

The PRECISION BRAND 14525 is a zinc-plated square keystock bar used to secure rotating components to shafts in mechanical drive systems. Measuring 1-1/8 inches square and 12 inches in length, this keystock transmits torque between a shaft and a hub, pulley, gear, or sprocket. The zinc plating provides a layer of corrosion resistance suited to light industrial and commercial environments. Each pack contains two pieces, making it practical for stocking or for jobs requiring multiple keys cut to length. Installation typically falls to maintenance mechanics and millwrights working on rotating equipment.

This keystock is used in a wide range of mechanical power transmission applications, including HVAC drive assemblies, pump drives, conveyors, fans, and general industrial machinery. It is sold in a pack of two 12-inch bars, which can be cut to the required key length on the job. The 1-1/8 inch square cross-section matches standard shaft keyway dimensions for larger shaft diameters common in commercial and light industrial equipment.

Key Features

• 1-1/8 inch square cross-section fits standard keyway dimensions for larger shaft sizes
• 12 inches length per bar allows field cutting to required key length
• Zinc plating provides corrosion resistance for light industrial environments
• Pack of 2 bars per unit for efficient stocking or multi-key jobs
• Functions as a torque-transmitting element between shaft and hub assemblies

Compatibility

Designed as a standard square keystock replacement for mechanical drive assemblies requiring a 1-1/8 inch square key profile, including pump drives, fan assemblies, and general power transmission applications.

Installation Notes

Keystock installation is typically performed by maintenance mechanics or millwrights. De-energize and lock out the drive system before removing any shaft-mounted components. The bar is cut to the required length using a bandsaw, hacksaw, or cold cut saw, then fitted into the shaft and hub keyways before the hub is secured. Verify keyway dimensions and tolerances against shaft specifications before cutting.
