T-Head Bolts (T-Slot Bolts DIN 261)
T-head bolts with a distinctive T-shaped head designed to slide into T-slots of machine tables, structural channels, and extrusion profiles. Conforming to DIN 261 standard, these bolts provide secure clamping and positioning in jigs, fixtures, machine tools, and structural steel connections. The T-head design allows fast assembly and repositioning without requiring access to the nut side.
