Description
If you’ve ever had a pulley slip on a shaft or a gear wobble because the keyway is worn out, you know how frustrating it can be when power won’t transfer properly. This square keystock gives you a simple way to fix shaft connections on everything from mower drives to hydraulic pump couplings. It’s the same material shops use to cut custom keys that’ll get your equipment spinning true again.
What You’re Getting
- Precision-cut 1/4-inch square steel bar that machines cleanly with standard tools
- 12-inch length gives you enough material for multiple keys or one long application
- Cold-rolled steel construction provides the strength to handle high torque loads
- Standard keystock dimensions work with common shaft and pulley keyway sizes
Built for Real Farm Work
This keystock fits a wide range of applications across tractors, implements, and shop equipment. Whether you’re repairing a worn key in a PTO shaft, fixing a slipping pulley on a hay baler, or replacing damaged keys in gearbox assemblies, this material cuts to whatever length you need for the job.
Made to Last
Farm equipment puts serious stress on shaft connections, especially when you’re running implements through tough conditions. This cold-rolled steel keystock has the hardness and strength to handle shock loads and prevent the shearing that can happen with softer materials. The precise dimensions ensure a tight fit that won’t develop play over time.
Good to Know
Most keys can be cut with a hacksaw and filed to fit, though a mill or grinder makes cleaner cuts if you’ve got access to one. Always file a slight radius on the corners to prevent stress concentrations that can cause cracking. Keep some extra keystock around the shop – you’ll be surprised how often you need it for repairs.
