Description
When you need to secure a bolt with a cotter pin for safety-critical connections, a slotted hex nut is the way to go. These nuts feature slots cut into the top that line up with holes in your bolt, letting you drop in a cotter pin to prevent the nut from backing off. It’s a time-tested design that’s been keeping tractor parts where they belong for decades.
What You’re Getting
- Precision-cut slots that align properly with standard bolt hole patterns
- 3/4-inch size with UNC thread pitch for common agricultural applications
- Grade 2 steel construction that handles everyday farm equipment loads
- Zinc plating provides rust protection for outdoor equipment storage
- Works with standard cotter pins to prevent loosening from vibration
Built for Real Farm Work
You’ll find slotted hex nuts on steering components, three-point hitches, implement connections, and anywhere safety requires a positive lock. The 3/4-inch size is common on medium to heavy-duty tractor connections where you need more strength than smaller hardware but don’t need the bulk of 1-inch bolts.
Made to Last
The zinc coating helps these nuts stand up to weather and field conditions without rusting out in a season or two. Grade 2 steel provides good strength for most farm applications without the premium cost of higher grades.
Installation Notes
Thread the nut on until snug, then continue tightening until the slots line up with your bolt’s cotter pin hole. If you go past alignment, back off to the previous slot rather than over-tightening. Always use a new cotter pin and spread the ends properly to keep everything secure.
