Introducing the Four Claw T Nut with Pointed Head DIN1624, 45 Steel, Black Oxide - a marvel in fastener design. The T-type four-claw nut is a uniquely engineered fastener, comprising a T-shaped head and four symmetrically aligned claw-like extensions. The T-shaped head features four elegantly rounded corners, while the central cylindrical body is threaded internally. Its four claws, crafted from elastic steel sheets or carbide materials, can dynamically contract or expand, providing unparalleled stability. This innovative design merges the load-bearing strength of a T-nut with the non-rotation guarantee of the four-claw configuration. Standard sizes range from M3-M12, in materials such as carbon steel, stainless steel 304/316, and galvanized models. The distinct side convex contour in the middle of the square base amplifies stability during installation through elastic deformation.
