The Cup Square Carriage Bolt & Nut BZP M8x40mm is a robust and reliable piece of hardware designed for secure fastening in a variety of applications. This bolt and nut set, featuring a bright zinc-plated (BZP) finish, offers excellent corrosion resistance. The square neck under the dome-shaped head of the carriage bolt stops rotation when tightening, making it ideal for use with timber and other soft materials. The M8x40mm size ensures compatibility with standard drill bits and fasteners.
