3/8 Inch Square Carbon Steel Key Stock - 12 Inch Length

Essential Hardware for Shop Fabrication and Repair

In any welding or fabrication shop, equipment downtime can halt production. The Walter Key Steel (48H469) is a vital repair staple for keeping your shop's machinery—from band saws to welding positioners—operational. This 3/8-inch square key stock is crafted from robust carbon steel, designed to withstand the mechanical stresses of power transmission. When a drive key shears or wears out, having this high-quality stock on hand allows for immediate replacement and a quick return to work.

This 12-inch bar of key steel is versatile and easy to work with. It can be cut to length with a standard hacksaw or abrasive chop saw and filed for a precision fit. The square profile is manufactured to strict tolerances, ensuring it seats firmly in both the shaft and hub keyways. This tight fit is crucial for preventing backlash and ensuring the longevity of the mating components. The carbon steel construction also allows for tack welding if the application requires a permanent fixture, although it is primarily designed for interference or set-screw fits.

Don't let a missing or broken key stop your project. The Walter 48H469 Key Steel is a cost-effective, high-performance solution for mechanical coupling needs. Its durability makes it suitable for heavy-duty use in agricultural equipment, automotive repair, and industrial fabrication setups. Add this essential hardware to your consumables inventory to ensure you are prepared for any mechanical maintenance task.
