Plow scraper bolts feature a countersunk, flat head, square neck, and unified thread pitch. They are used in snowplow blades, bulldozers, road graders, scoop shovels, and other heavy-duty industrial equipment where a flat, smooth surface is required. Our B1323-series scraper bolts are made at a higher hardness and strength (170,000 P.S.I.) than standard grade material. This means additional wear resistance for demanding scraper blade applications.
