T-Bolt T-Head Bolt | Hammer Head Bolt for Marine T-Slot
TheT-Bolt—also termed T-Head BoltorHammer Head Bolt—features a flat rectangular or hammer-shaped head that inserts into a T-slot channel from the side and rotates 90° to lock, eliminating the need for back-side access during assembly. This design enables continuous adjustment along the full length of the slot before final torquing, making it the preferred fastening solution for any application requiring flexible, repositionable equipment mounting on slotted rails, structural channels, and aluminum extrusion profiles.
On ship decks, T-Slot Bolt assemblies secure movable equipment foundations in T-slot deck plating common on offshore support vessels, research vessels, and workboats. They fix solar power module frames in aluminum extrusion racking systems, mount adjustable fairlead and deck hardware on channel rail systems, and connect container lashing fittings in deck cargo securing arrangements. The Hammer Head Bolt profile matches standard 41×41mm strut channel and DIN 508 machine table T-slots, ensuring direct compatibility with existing vessel deck hardware. Grade 8.8 carbon steel variants with blue zinc or PTFE coating deliver corrosion resistance for above-deck service, while SS304 T-Bolt options provide stainless performance for exposed marine environments.
