Our hexagon bolts with studs in accordance with DIN 561 in strength class 8.8 offer the ideal solution for form-fit clamping connections in T-slots and fixture systems. The machined tang at the end of the screw prevents twisting in the groove and enables precise positioning. The combination of hexagon head and tang ensures maximum stability – even with high clamping forces. <\/p>\n
