Sinorock provides domed nut, hex nut, and spherical collar nut, all crafted from high-quality steel. The domed nut boasts a chamfered edge at one end, whereas the hex nut features chamfered edges on both ends. The hex nuts are primarily utilized in combination with flat plates, and the domed nut and spherical collar nut are predominantly used in combination with domed plates.
All nuts exceed the ultimate strength of the self-drilling rock bolt and can meet the stringent requirements of anchor specification. In addition, Sinorock offers anti-corrosion treatments for rigorous construction requirements, including hot-dip galvanizing and double corrosion protection coatings.
