Description
When you’re working on your tractor or farm equipment, you need hardware that won’t let you down. This Grade 5 hex bolt delivers the strength and reliability you’re looking for when securing heavy-duty components that take a beating in the field. The zinc finish helps protect against rust and corrosion, so you won’t be dealing with seized bolts down the road.
What You’re Getting
- Grade 5 strength rating handles medium to heavy-duty applications without stretching or breaking
- Zinc plating resists rust and corrosion in tough farm environments
- UNC thread pitch matches standard farm equipment specifications
- 4-inch length provides plenty of thread engagement for secure connections
- 5/8-inch diameter offers excellent holding power for substantial loads
Built for Real Farm Work
This bolt is perfect for securing implements, mounting brackets, loader attachments, and other equipment where you need serious holding power. Whether you’re bolting on a brush hog, mounting hydraulic cylinders, or assembling three-point hitch components, Grade 5 bolts are the sweet spot between everyday hardware and expensive Grade 8 bolts for most farm applications.
Made to Last
Grade 5 bolts are heat-treated to handle significantly more stress than standard bolts, making them ideal for equipment that vibrates, flexes, and takes punishment during normal farm work. The zinc coating adds an extra layer of protection against the elements, helping these bolts stay serviceable season after season.
Good to Know
Always use the proper grade washer and nut with Grade 5 bolts to get the full strength benefit. A little anti-seize compound on the threads makes future removal much easier, especially on equipment that sits outside. Keep the threads clean during installation for proper torque values.
