Specially designed features include: • Thicker than standard bolt head adds wrenching surface • Washer face eliminates corner drag • Radius under bolt head adds strength • Countersunk washer inside diameter centers the washer against the bolt head bearing surface during tightening • UNR Radiused root bolt thread increases fatigue resistance by reducing the notch effect of conventional UN threads. • UNR Thread radius is maintained into the thread run-out at the junction of thread to shank • Smooth washer bearing surfaces distribute loads uniformly and reduce brinneling. • Plated finish assists torquing • Chamfers eliminate corner drag • Thicker than standard nut side walls facilitate wrenching • Heat treating helps prevent splitting and stripping
