Mak-a-key C207-360807305 Oversized Key Stock 12in Steel

Product Description

The MAK-A-KEY C207-360807305 is an oversized key stock used to secure rotating components to shafts in mechanical drive systems. Made from C1045 steel with a zinc-plated finish, this key stock resists corrosion and holds up in demanding industrial and trade applications. Each piece measures 12 inches in length, 8.00 millimeters in height, and 7.00 millimeters in width. This package includes 5 pieces, making it a practical stock item for shops, maintenance crews, and millwrights who regularly service power transmission equipment.

Oversized key stock is commonly used in mechanical assemblies where standard key dimensions do not provide adequate fit or where worn keyways require an oversize key to restore proper torque transfer. Typical applications include pump drives, conveyor systems, fan shafts, compressor couplings, and other power transmission assemblies found in both light commercial and industrial settings. Licensed millwrights, maintenance mechanics, and HVAC technicians working on belt-drive or direct-drive equipment will find this stock suitable for on-the-spot fabrication and repair work.

Key Features

• Oversized profile restores fit in worn or enlarged keyways without full shaft replacement
• C1045 steel construction provides high tensile strength for torque-transfer applications
• Zinc-plated finish adds corrosion resistance for extended service life
• 12-inch length allows field cutting to custom lengths as needed
• Package of 5 pieces supports efficient shop stocking and repeat service calls

Compatibility

Designed as an oversized replacement key stock for mechanical shaft and keyway assemblies requiring an 8.00 millimeter by 7.00 millimeter cross-section profile.

Installation Notes

Key stock installation is typically performed by millwrights or mechanical maintenance technicians. De-energize and lock out all power to the drive system before removing or installing any shaft components. Key stock is generally cut to length using a metal saw or grinder and deburred before fitting. Verify keyway dimensions on both the shaft and hub before selecting key stock size to ensure proper fit and torque transfer.
