Description
When a key breaks on a pulley or belt drive, it’s one of those repairs that can shut down your whole operation until it’s fixed. You’ve probably been there—shearing off a key in the middle of harvest or when you’ve got hay down and weather coming. Having good keystock on hand means you can cut a new key and get back to work instead of making a trip to town and hoping they’ve got what you need.
What You’re Getting
- High-quality 1018 cold rolled steel that machines easily and holds up to heavy loads
- Square cross-section cuts precise keys that fit tight in keyways without slop
- 12-inch length gives you enough material for multiple keys or custom applications
- ASTM A108 specification steel ensures consistent strength and machinability
Built for Real Farm Work
This keystock is sized for the smaller shafts you’ll find on belt drives, PTO connections, and implement drives across all kinds of tractors and farm equipment. Whether you’re keying a pulley on an old combine, fixing a feed mixer drive, or rebuilding a hay baler, this size handles the torque loads these machines put on drivetrain components.
Made to Last
Cold rolled 1018 steel is the go-to material for keystock because it’s tough enough to handle the shock loads farm equipment dishes out, but it’s still soft enough to cut and file by hand when you need to fit it just right. The cold rolling process gives it a smooth finish and precise dimensions that make for tight-fitting keys.
Good to Know
Keep a few pieces of different keystock sizes in your shop—when you need it, you really need it. This material cuts easily with a hacksaw or cutoff wheel, and you can file the ends to get the perfect fit. Remember to check your shaft and keyway dimensions before cutting, and always chamfer the edges slightly so the key slides in smooth.
