Products Description
As one of the most essential fasteners for industrial aluminum profile frame construction, T-bolts, also known as boat-shaped bolts and hammer head bolts, are specially designed for in-groove connection of European and national standard aluminum profiles. They are key parts to rapidly fix profiles with angle brackets, plates and various accessories.
Common Names: T-screw, hammer head bolt, boat-shaped bolt
Core Structure
Consists of T-shaped head matching profile grooves and full-thread screw rod. The head can slide directly into profile grooves and lock tightly after rotating 90 degrees. No thread tapping or welding is required.
Compatibility
Fit for European standard 20/30/40/45 series aluminum profiles with 6mm, 8mm and 10mm groove widths, also compatible with most GB standard profiles.
Material Selection
8.8 Grade Carbon Steel: Zinc-plated or nickel-plated finish with good rust resistance and wear resistance, cost-effective for ordinary workshop use.
304 Stainless Steel: Superior corrosion resistance, suitable for humid, clean and food-grade working environments.
Surface Treatment
Blue-white zinc plating, color zinc plating or original polished stainless steel finish.
Core Advantages
Easy Installation Without Thread Tapping
Slide the T-head into the groove and rotate 90° for positioning. Fasten quickly with flange nuts or spring nuts. No tapping needed, easy to disassemble and restructure to meet flexible lean production demands.
Wide Compatibility
Perfectly matched with angle brackets, connecting plates, leveling feet, casters, handles and nearly all aluminum profile accessories, widely used in various profile assembly projects.
Firm Connection & Anti-loosening Performance
The T-head fits closely with profile grooves to form large contact area after tightening. It offers better anti-loosening effect than ordinary screws, ideal for vibrating assembly lines and conveyor equipment.
Concealed Installation
The whole bolt is hidden inside profile grooves without outer protrusion, keeping smooth surface for neat appearance and safe operation.
