OVERVIEW

Reliable 3/8" Square Key Stock for Machinery Repair

Keep your shop equipment and industrial machinery running smoothly with Walter 48H380 Key Steel. In the world of welding and fabrication, equipment downtime can be costly. Having reliable repair parts on hand, like high-quality key stock, is essential for fixing drive mechanisms on welding positioners, band saws, and grinders. This 3/8" x 3/8" square bar is 12 inches long, providing ample material to cut multiple replacement keys for various applications.

The standout feature of this product is its oversized tolerance. Standard stock often fits loosely, leading to wear and eventual failure of the keyway. Walter's oversized specification ensures a snug, interference fit that locks components firmly in place, transferring torque efficiently without slippage. Additionally, the zinc-plated finish sets this product apart from plain steel stock, offering excellent resistance to humidity and shop fluids. This means you can keep it in your tool crib without worrying about finding a rusty bar when you need it most. It is an indispensable item for any MRO (Maintenance, Repair, and Operations) inventory.
