Value Collection 33970 Undersized Key Stock 7/8x7/8x12 Steel

Product Description

The VALUE COLLECTION 33970 is an undersized key stock bar used to secure rotating components to shafts in mechanical drive assemblies. Machined from cold drawn steel with a plain finish, this key stock provides consistent dimensional accuracy and the tensile strength needed for reliable power transmission. At 7/8 inches high, 7/8 inches wide, and 12 inches long, it is sized for standard keyway applications where undersized tolerances are required for proper fit and function. Machinists, millwrights, and maintenance technicians use key stock like this when assembling or replacing couplings, pulleys, sprockets, and gears on rotating shafts.

This key stock is suited for industrial maintenance, OEM assembly, and general mechanical repair work. The 12-inch length allows technicians to cut the stock to the required key length for a given shaft and hub combination. The undersized cross-section is intended for keyways that call for a looser fit tolerance, which is common in applications where ease of assembly or slight clearance is preferred. Cold drawn steel construction makes this stock appropriate for moderate-duty drive applications across manufacturing, HVAC equipment, and rotating machinery platforms.

Key Features

• Undersized key stock type for applications requiring clearance-fit keyways
• Cold drawn steel construction for consistent tensile strength and dimensional control
• 7/8 inches x 7/8 inches cross-section with 12-inch usable length
• Plain finish allows for direct installation or surface treatment as needed
• Cuttable to required key length on-site with standard metalworking tools

Compatibility

Designed as a general-purpose undersized key stock for use in rotating shaft and hub assemblies requiring a 7/8-inch square keyway profile.

Installation Notes

Key stock installation is typically performed by machinists or millwrights. De-energize and lock out all power to the equipment before removing or installing any shaft-mounted components. Cut the key stock to the required length using a bandsaw, angle grinder, or mill, and deburr all cut edges before fitting. Follow applicable machinery safety standards and equipment manufacturer procedures when assembling shaft-to-hub connections.
