Definite Metal manufactures and exports DIN 186 T-head bolts with square neck in brass, produced in Jamnagar, India. The T-shaped head slides into machine T-slots while the square neck locks the bolt against rotation during tightening — making these fasteners standard for machine-tool clamping, fixtures, jigs and slotted-table mounting. We produce them in free-machining brass CW614N and forging brass CW617N, in metric and imperial sizes with custom lengths manufactured to your drawing or sample. Also available in MS and SS 303/304/316 on request. For matching T-slot nuts, see our DIN 508 and ISO 299 nuts for T-slots.
