What Are Plow Bolts?

Plow bolts are a specific style of heavy-duty threaded fastener that is commonly used in construction, snow plow, and other heavy machinery. This style of bolt is recognizable because it is specifically designed to not turn after it is tightened with a matching nut and because it typically is flush to the surface. The non-protruding head of a plow bolt makes them ideal for blades in graders and snowplows because it allows the material to pass over the bolt head without obstructing the moldboard.

Plow bolts feature a countersunk square neck under the head of the bolt, which prevents the bolt from turning when threaded with a nut of the same thread. The square locking base width is the same size as the bolt diameter. Plow bolts are available in different head styles; No.3 head, flat head, domed/convex head, clipped head, or elliptical/tapered head. The bolt may also have a finish to protect against corrosion.

 

ITR plow boltsGrade 8 Plow Bolts

There are various types of plow bolts, based on the strength of the steel. The strength is specified with a numerical grade (if in inches, or in numerical class if metric) to denote the composition and performance grade of the material. DMC Wear Parts offers many grade 8 bolts, which are made of high-strength steel. Grade 8 plow bolts have a high carbon content and are composed of a heat-treated steel alloy. In contrast, grade 5 bolts are made from medium-grade steel that has a lower tensile and load strength.

For more information reference the American Society of Mechanical Engineers Standard ASME B18.9, Plow Bolts, for more specifications on plow bolts.

 

Track Bolts

DMC also offers a selection of track bolts for tough applications. These bolts are designed to provide a perfect fit, excellent field performance, and high strength. Download The Track Bolt Product Catalog for more information.
