The CORE-BULK Carriage Bolt \& Nut BZP M8x50mm is a fastening solution designed for various mechanical and construction applications. It features a domed or rounded head with a square neck underneath to prevent turning during the tightening process. The bolt comes with a matching nut, and both are finished with Bright Zinc Plating (BZP) for added corrosion resistance. The dimensions indicate that it is an M8 bolt, 50mm in length, which is a standard size for medium-duty tasks that require secure fastening. The pricing unit of measure suggests the item is sold individually, making it suitable for both small scale projects or as part of a larger order.
