L shape screws are widely used in structural and assembly applications where angled fastening is required. Commonly manufactured from carbon steel or stainless steel (such as SUS304 or Grade 8.8 materials), these fasteners feature a 90-degree bend that allows them to serve dual functions—both as a screw and a mechanical hook or anchor. Their design is often utilized in securing door hardware, cabinetry systems, electrical enclosures, or wall-mounted components where standard linear fasteners are not feasible.
Available in thread sizes ranging from M4 to M12 and lengths from 20mm to 100mm, L shape screws may incorporate either coarse or fine threading depending on the substrate material. Some variants include partial threading to improve load distribution or anti-slip performance. Popular finishes include zinc plating, hot-dip galvanization, or black oxide for corrosion resistance in outdoor or high-humidity environments.
L shape screws often come with hex heads or slotted drive ends for easy torque application, and may conform to DIN 479 or customized specifications. Their versatility, load-bearing angle, and ease of installation make them indispensable in both commercial and industrial sectors requiring dependable angled fastening solutions.
