Description
Nothing stops a job faster than a sheared shaft key. Whether you’re fixing a busted mower deck drive or getting a spreader back in action, having keystock on hand means the difference between a quick repair and a trip to town. This 1/2 inch square steel keystock is the standard size for many farm implements and gives you 12 inches to work with—enough for several repairs or one long application.
What You’re Getting
- Premium carbon steel construction that won’t break under high torque loads
- Precision-cut 1/2 inch square profile that fits standard keyways perfectly
- 12-inch length gives you plenty of material for multiple repairs or custom cuts
- Clean, burr-free finish that slides into keyways without binding
- Standard sizing means it’ll match OEM specifications on most equipment
Built for Real Farm Work
This keystock is sized for the heavy-duty equipment that keeps farms running. You’ll find 1/2 inch keys in PTO shafts, implement drives, mower deck spindles, and gearbox connections on everything from bush hogs to hay balers. It’s the same spec steel that equipment manufacturers use, so your repair will hold up just like the original part.
Made to Last
Farm equipment keys take a beating from shock loads, vibration, and constant power transmission. This keystock is made from quality carbon steel that’s been properly heat-treated for the right balance of strength and toughness. It won’t snap under sudden loads but also won’t be so hard that it damages your expensive shafts and hubs.
Good to Know
Measure your keyway carefully before cutting—it’s easier to take off a little more than to start over. A good hacksaw or cutoff wheel works fine for cutting to length. File or grind any rough edges smooth so the key slides in easily. Keep the cut pieces in your toolbox—you’ll use them sooner than you think.
