introduction to products：
Brass hex bolts: These bolts feature a hexagonal head and a threaded shank. Crafted from high - quality brass, which is an alloy mainly composed of copper and zinc, they possess excellent corrosion resistance, good electrical conductivity, and a visually appealing golden appearance. Brass hex bolts are relatively softer compared to some steel bolts, making them suitable for applications where there's a need to prevent scratching of mating surfaces or where electrical conductivity is required. They come in various sizes, such as M4, M6, M8, etc., and different lengths to meet diverse fastening needs. These bolts are widely applied in electrical equipment, plumbing systems, decorative hardware, and some light - duty mechanical applications. For example, in electrical cabinets, they are used to connect electrical components due to their conductivity; in plumbing, they help fasten pipes and fittings; and in decorative projects, their golden color adds an aesthetic touch.
Instructions for Use：
Brass hex bolts are used to fasten two or more components together. First, ensure that the holes in the components to be fastened are of appropriate size. For through - holes, a nut is usually required. Insert the brass hex bolt through the holes, and then use a wrench that matches the size of the hexagonal head (such as a socket wrench or an open - end wrench) to tighten the nut or directly tighten the bolt into a threaded hole. When tightening, do not apply excessive force as brass is softer and may strip the threads. Tighten to a degree that ensures a firm connection while avoiding damage to the bolt or the connected components.
