Plow Bolts

Commonly found in farm, road construction, and other heavy equipment, plow bolts are heavy duty fasteners with non-protruding heads. A square neck prevents turning of the bolt.

Finish

Plain

Nothing has been done to this bare metal surface to improve appearance or corrosion resistance, which is very low if the material is steel. Often the surface has been oiled which improves lubricity. This finish is susceptible to rusting and corrosion in exterior environments. This most basic finish can be used when protection is not an issue or indoors.
Yellow Zinc

This iridescent electroplated zinc finish, also known as Yellow Zinc Chromate or Dichromate, provides very good corrosion resistance and protection against rust. This finish should not be used in marine or high salt spray environments.
Zinc

This finish, also know as zinc plating, zinc chromate or dichromate provides good corrosion resistance and is the standard for many hardware fasteners. It is an electroplated zinc layer covered with a chromate post-treatment. The zinc protects the steel from corrosion and the chromate layer protects the zinc from degrading. It is a popular finish because of its protection, value, and ease of coating. Slightly less corrosion resistant than yellow zinc, it is a versatile finish that is best used indoors. This finish should not be used in marine or high salt spray environments.

Grade

5

This grade is from the SAE scale. Made of medium to low carbon steel, it is of medium strength on the grade scale.
8

This grade is part of the SAE classification; it is the minimum standard of the automotive and structural industries, plus it is used in high-temperature applications. Grade 8 is near the high end of the grade scale, although there are higher grades and strengths for more specialized fasteners.

Material

Steel

Steel is the most common fastener material due to its strength properties. Unalloyed steel may be surface treated to enhance corrosion resistance and other desirable properties.

Type

Plow Bolt

Plow bolts are used in bulldozers, snowblades, and other heavy equipment in which a smooth fastener head lessens wear.
Plow Bolt - Bucket Tooth

Bucket tooth plow bolts feature a key to keep the fastener head in place while threading the nut.
