Description

When you’re assembling implements, fixing brackets, or building shop projects, you need fasteners that’ll hold up to the constant vibration and stress of farm work. This 1/4-inch carriage bolt with its smooth, rounded head and square shank design locks into place so it won’t spin when you’re tightening the nut—exactly what you want when you’re working on equipment that needs to stay together.

What You’re Getting

  • Grade 5 steel construction that’s tougher than hardware store bolts but won’t break the budget
  • Zinc plating protects against rust and corrosion for seasons of reliable service
  • Square shank design grips square holes to prevent spinning during installation
  • 4-1/2 inch length handles thick materials or multiple layers that need sandwiching together
  • UNC thread pitch matches standard agricultural equipment specifications

Built for Real Farm Work

This size carriage bolt is perfect for lighter-duty connections on implements, shop-built equipment, and repair projects. You’ll find it ideal for securing brackets, mounting lighter components, and assembling equipment where you need reliable fastening without the bulk of larger bolts. The 4-1/2 inch length gives you plenty of thread engagement even when working with thick materials or multiple mounting plates.

Made to Last

Grade 5 bolts offer the sweet spot between strength and cost—they’re about 25% stronger than Grade 2 hardware store bolts but cost less than Grade 8. The zinc coating helps them stand up to moisture and road salt, so they won’t rust out on you in a season or two. This bolt is built to handle the vibration and loads that come with everyday farm equipment use.

Installation Notes

The square shank is designed to bite into square holes or softer materials to prevent rotation. Always use a flat washer under the head and nut to distribute the load properly. A little anti-seize compound on the threads makes future removal much easier, especially if the connection might see heat or road salt.
