Stainless Steel T Head Bolts (GB/T 37 standard), also known as T-slot hammer bolts, are specialized fasteners with a square T-shaped head conforming to the Chinese GB/T 37 standard. The T-head can slide freely within the T-groove of aluminum profiles and lock in place when tightened. They are commonly manufactured from 304 or 316 stainless steel, providing excellent rust and corrosion resistance for indoor and humid outdoor environments. Designed in accordance with GB/T 37 standard, the square T-shaped head can be directly inserted and slid into the T-slot of aluminum extrusion profiles. During assembly, the T-head will self-lock to prevent rotation, which streamlines installation without extra positioning. Featuring stable clamping force and high reusability, these GB37 T head bolts are widely used for aluminum profile frame assembly, machine guard frames, workbench construction, automation equipment and industrial enclosure connections.
