SKU: SMA-120-85012 3/4 Inch Slotted Hex Nut - Grade 2 Zinc Plated

When you need a nut that stays put but still gives you the option to lock it down tight with a cotter pin, this slotted hex nut gets the job done. The slots let you use a cotter pin or safety wire to keep critical bolts from backing out when your equipment is working hard in the field. It's the kind of reliable fastener that helps prevent those frustrating breakdowns that always seem to happen at the worst time.

What You're Getting

• Grade 2 steel construction handles everyday farm equipment loads without issue
• Zinc plating provides solid corrosion protection against moisture and chemicals
• Precision-cut slots accept standard cotter pins for positive locking action
• 3/4 inch UNF fine thread gives you more threads per inch for better holding power
• Standard hex shape works with your regular wrenches and sockets

Built for Real Farm Work

This nut is sized right for mid-duty applications on tractors, implements, and equipment where you need that extra security of a cotter pin lock. Whether it's securing wheel bearings, linkage pins, or hydraulic fittings, the combination of fine threads and positive locking keeps things tight through all the vibration and stress of field work.

Made to Last

The zinc coating does its job protecting against rust and corrosion, while the Grade 2 steel provides plenty of strength for most farm applications. These nuts are built to handle the temperature swings, moisture, and chemical exposure that come with agricultural work season after season.

Good to Know

Fine threads give you more precise adjustment and better holding power than coarse threads, but they take a bit more care during installation. Make sure your threads are clean and use a little anti-seize on the bolt threads if you're working in a high-corrosion environment. The cotter pin slots are sized for standard pins, so keep a variety pack handy in your toolbox.
