Long-Tail Screw
Specially designed for thick steel plates, the Long-Tail Screw features an extended drilling point that enables secure fastening into materials up to 30mm thick. With outstanding penetration power and installation stability, they’re the trusted choice for high-strength environments such as steel structures, machinery, and heavy-duty applications.
Description
A long tail screw is a specialized fastener with an extended, sharp pointed tip (long tail) that allows for deeper penetration and faster installation into thick or dense materials. It provides strong holding power.
Screw King’s Long-Tail Screw is engineered for high-performance fastening in demanding structural environments, specifically designed to directly penetrate thick steel plates (10mm–30mm) without the need for pre-drilling. Its extended drilling tip and reinforced design make it an ideal solution for heavy-duty construction and industrial applications where strength and efficiency are critical. This screw delivers reliable penetration, stable fastening, and reduced installation time—making it a trusted choice for large-scale engineering projects.
We offer a wide variety of head types to choose from, including head shape, hex washer head, flange head, as3566, flower head, truss head, pan head, oval head, bugle head, flat washer head, small flat head, flat head, wafer head, cheese head, and more. Screw King is a professional long screw manufacturer in Taiwan. Please feel free to contact us for further information.
