 * In a certain range, tensile strength increases in  proportion to hardness. For couplers or nuts, it's  important to make sure the fitting capacity with bars  must reach bar's capacity itself. Through hundreds of  rounds of testing, SupAnchor sets up a lab standard  which is HRC 23 – 30 for couplers and HRC 25 – 30  for nuts. SupAnchor's products have achieved 100%  safe application over 15 years.
