This cup square bolt and nut set features a bright zinc plated finish and measures M6 x 150mm, making it suitable for fixing thicker sections of timber or metal. The square head profile ensures a low, flush fit once tightened, helping to reduce snagging on surfaces in joinery, fencing, or general assembly applications.
Typically, these fasteners are installed through pre-drilled holes in structural components, with the square neck preventing the bolt from rotating during installation. The provided nut allows for straightforward tightening from one side, offering convenience on site where access may be limited.
