Frequently Asked Questions (FAQs)
1. What is a plow bolt used for?
Plow bolts are primarily used to attach the plow share (blade) to the frog (frame) to allow the earth to pass over their heads without obstruction. They are also used for fastening the blade to bulldozers and motor graders.
2. What is the difference between a carriage bolt and a plow bolt?
While carriage bolts are commonly used in wood, they may also be referred to as plow bolts. Carriage bolts have a domed top and a square under the head, which pulls into the wood as the nut is tightened. Plow bolts, available in various diameters, are a versatile choice for different applications.
3. What size are plow bolts?
Plow bolts come in different sizes. Flat head plow bolts range from 3/8" to 3/4" in diameter, while dome head plow bolts range from 5/8" to 1" in diameter. Lengths vary depending on the size, ranging from about 1" to 4" for flat heads and 1 1/2" to 7" for dome heads.

A plow is typically attached to a truck using brackets or a two-inch hitch receiver. There are also rear-mount plows available that connect via the same hitch receiver used for trailers.
6. What holds a plow on a truck?
For non-commercial use, a front receiver hitch is commonly used to attach a snow plow to a truck. Installing the hitch allows for easy attachment of the plow by sliding its attachment point into the receiver and securing it in place.
7. What does a plow bolt look like?
Plow bolts are characterized by their flat and tapered head. When installed, the head becomes countersunk under the surface of the wooden object.

Structural screws serve various functions and are easier to use than carriage bolts. Made from hardened heat-treated steel, structural screws can be thinner than lag bolts while still holding as much or more weight.
