This system offers high-grade alloy steel cap screws, high strength, extra thick hex nuts, thru-hardened flat washers and size-marked cap screw and flat washers. Additional features and benefits include: cap screw for easier wrenching, hex nut that requires less torque to generate consistent clamp loads and a flat washer to provide a smooth bearing surface for load distribution.
