Carbon steel zinc plated bolt and nut

Stainless Steel Nuts And Bolts are used for fastening and joining two connected parts and structures with through holes. According to the type of Stainless Steel Bolts, it can be divided into stainless steel hexagonal head bolts, stainless steel hexagonal flange bolts, stainless steel square head bolts, semicircular head (square neck or tenon) bolts, countersunk head (square neck or tenon) bolts tenon) bolts, T-shaped Slot bolts, stainless steel swing bolts, stainless steel anchor bolts and other types. Let's talk about the respective uses of these stainless steel bolts in detail.
          Stainless steel hex head bolts are the most widely used bolt type. A and B grade bolts are used in important occasions that require high assembly accuracy and are subject to greater impact, vibration or alternating loads. C-grade bolts are used in occasions where the surface is relatively rough and assembly accuracy is not high. The threads of Stainless Steel Bolts are generally coarse-tooth ordinary threads, and the bolts with West Asian ordinary threads have better self-locking performance. Stainless Lag Bolts are mainly used for thin-walled parts or where they are subject to shock, vibration or alternating loads. Generally, bolts are partially threaded, and fully threaded bolts are mainly used in occasions where the nominal length of the bolt is short and a long thread is required. Bolts with holes are used in occasions where bolt locking is required. Bolts with reamed holes can accurately fix the mutual position of the connected parts, and can withstand shear and extrusion caused by lateral force.
         The head of the stainless steel hexagon flange bolt is composed of two parts, the hexagon head and the flange surface, and its "support area to force area ratio" is larger than that of ordinary hexagon head bolts, so this bolt can withstand higher preload. The loose performance is also very good, Stainless Steel Lag Screws are widely used in automobile engines, heavy machinery and other products.
