The T-type four-claw nut is a specially designed fastener, mainly composed of a T-shaped head and four symmetrically distributed claw-like structures. Its head is in the shape of a T-shaped plate, with four arc-shaped rounded corners, and a cylindrical body with internal threads in the middle; the four claws are evenly distributed around the base, and are made of elastic steel sheets or carbide materials, which can shrink inward or expand outward. This structure combines the load-bearing advantages of the T-nut and the anti-rotation characteristics of the four-claw design. The standard specifications cover M3-M12, and the materials include carbon steel, stainless steel 304/316 and galvanized models. The uniqueness lies in the side convex design in the middle of the four sides of the square table, which enhances the stability after installation through elastic deformation.
