Mak-a-key 8007500750-12 Undersized Key Stock 316 Ss

Product Description

The MAK-A-KEY 8007500750-12 is a square-profile undersized key stock bar used to transmit torque between a shaft and a hub, pulley, sprocket, or gear. Manufactured from Type 316 stainless steel, it offers strong corrosion resistance in wet, marine, and chemical-exposure environments where carbon steel or standard 304 stainless would be inadequate. This piece measures 0.75 inches high by 0.75 inches wide by 12 inches long and weighs approximately 1.91 pounds. Undersized tolerancing allows it to slide into keyways without interference fitting, making field cutting and installation straightforward for maintenance technicians and millwrights.

This key stock is suited for pump shafts, conveyor drives, fan assemblies, and similar power-transmission applications in commercial, industrial, and marine settings. The 316 stainless composition makes it a preferred choice wherever chloride exposure, saltwater splash, or chemical washdown cycles are a routine part of the operating environment. It ships as a single 12-inch bar, ready to be cut to the required finished length on-site or in the shop.

Key Features

• Type 316 stainless steel construction for superior corrosion and chloride resistance
• Undersized tolerance profile for straightforward keyway insertion without interference fitting
• Square cross-section: 0.75 inches high by 0.75 inches wide for high-torque applications
• 12-inch bar length allows field cutting to final required dimension
• Single-piece package with a minimum order quantity of one bar

Compatibility

Designed as an OEM-style replacement or service-stock key for standard 0.75-inch square keyway applications in power-transmission assemblies requiring corrosion-resistant fastening components.

Installation Notes

Key stock installation is typically performed by a millwright, maintenance technician, or mechanical contractor. Lock out and tag out all power sources before removing or installing key stock in any rotating assembly. Use appropriate metal-cutting tools to trim the bar to finished length, and deburr all cut edges before seating to prevent keyway damage. Follow applicable machinery safety standards and equipment manufacturer torque guidance when securing shaft-hub connections.
