Product Description
304 Stainless Steel T-Slot Bolts
Our 304 Stainless Steel T-Slot Bolts are specially designed fasteners for T-slots, slot rails, aluminum profiles, machine tool fixtures, clamping systems, and industrial assembly applications. The T-shaped head allows the bolt to slide into a slot and lock firmly when tightened with a matching nut.
Made from high-quality 304 stainless steel, these T-slot bolts provide good corrosion resistance, clean appearance, and reliable fastening performance. They are suitable for both indoor and outdoor use, especially where rust resistance and durable assembly are required.
Available in common metric sizes including M6, M8, M10, M12, and M16, these bolts are widely used in machinery, automation equipment, aluminum extrusion frames, workbenches, jigs, fixtures, and custom industrial structures.

What Is a T-Slot Bolt?
A T-slot bolt is a special bolt with a T-shaped or hammer-style head. The head is inserted into a T-slot or channel, then the bolt can slide along the slot to the desired position. After tightening the nut, the T-head locks inside the slot and provides a strong clamping connection.
This design is very useful for adjustable structures, fixtures, machine tables, aluminum profile frames, and industrial equipment.
