The trox groove design of Anti Tamper Screws provides greater torque transmission during the tightening process, effectively reducing the risk of slipping teeth and improving the efficiency and reliability of tightening. It can easily handle both manual and electric tool usage scenarios. The design with pillars increases the strength and stability of the nail.

The Truss Head Machine Screw adopts a unique head design and has a large flat shape, endowing the screw with many advantages. It is widely used in many fields such as industrial production, construction installation, furniture manufacturing, and electronic equipment assembly. The Head of the Truss Head Machine Screw is large and flat, which can provide a wide support surface, effectively disperse the pressure and prevent the material from being damaged due to excessive local force.​

Hex Black Lag Screws are screws specifically designed for connecting wooden products. Its head design is hexagonal, which not only facilitates tightening with a screwdriver or wrench, but also provides good grip and stability. The blackened surface is a treatment process that uses a special technique to form a uniform and dense oxide film on the surface of the screw. This treatment not only improves the anti rust ability of the screw but also enhances its surface glossiness, making it more beautiful and durable.

Hex socket head flange screws usually have a flanged head shape, which can provide a larger support area, enhance the shear and tensile resistance performance, and reduce the indentation of the bolt head on the base material.

Cross Pan Head Thread Cutting Screws are self tapping screws with a cross groove pan head design and a tail cut treatment. The design of this screw allows it to be inserted directly into the material without the need for pre threading during installation, forming a secure connection. The cross groove disc head design allows screws to be tightened using a cross screwdriver, making it convenient and fast.

Hexagon Socket Head Cap Screw has a hexagonal shaped head design, so that screws can withstand large torque during installation, providing reliable tightening effect, which is widely used in many fields.
