* 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.
