T-Head Bolt — T-Slot & Channel Fastening
A T-head bolt has a rectangular flat head shaped like the letter T, sized to fit into a matching T-slot. When the bolt is rotated 90° after insertion, the head locks into the slot. T-head bolts are common in machine tool fixturing, modular framing systems (Bosch, 80/20-style), and adjustable mounting.

Frequently Asked Questions
Are T-head bolts the same as T-slot bolts for aluminum extrusion?
T-head bolts and T-slot nuts/bolts share a similar concept but differ in execution. Aluminum extrusion systems (Bosch Rexroth, 80/20, MiSUMi) typically use specific T-slot nuts that drop into the slot from the end and slide into position. Traditional T-head bolts are rotated into the slot. Always match the bolt to the specific slot profile.
