Copper hex socket head cap screw is a type of fastener made of copper material. As its name indicates, the head of the screw is a special type of cylinder with hex socket entrance. Compared with other types of heads, the copper hex socket cap screw has good conductivity and heat spreading ability, and it also has excellent resistance to corrosion. It can be widely used in electrical devices requiring conductivity and anti-rust. In addition, hex socket enables the screw to be installed and removed easily with an appropriate hex driver and ensure the best fastening performance.

Brass Slotted Cylinder Head Screw is the fastener with brass materialized cylinder head and straight (slotted) drive slot. Brass has good resistance to corrosion and conductivity. So it can be used in rusted prevented area or electrical conduction required area. It is widely used in electronics, appliance, decoration hardware etc.

This mixed content kit contains pure titanium socket head cap screws and nuts with flat washers (pure titanium plain washers and spring washers). Pure titanium has excellent characteristics such as light weight, high strength, and corrosion resistance, and is widely used in parts with requirements such as lightweight, high rigidity, and high strength. Socket head cap screws are easy to install and remove, and flat washers and spring washers are used together to improve connection stability and sealing performance.

The density of aluminum alloy material is only one-third of that of steel, which can significantly reduce the overall weight in large structures. The surface of aluminum alloy naturally forms a dense oxide film, which, combined with anodizing treatment, can resist salt spray testing for more than 1000 hours, far exceeding the 500 hours of stainless steel. The conductivity of aluminum alloy is 4 times that of steel, and its thermal conductivity is 2 times that of steel, effectively avoiding loose connections caused by differences in thermal expansion coefficients.

The shape of the Aluminum Alloy Hexagonal Round Head Screw breaks through the sharp design of traditional bolts, with a rounded surface that not only fits tightly with the connector, reducing the risk of stress concentration, but also significantly reduces scratches or damage caused by accidental collisions. The hexagonal groove forms multi-point contact with the specialized wrench, resulting in high torque transmission efficiency.

Titanium Alloy Countersunk Machine Screw is the fastener which is made up of titanium alloy and it is counted sunk with flat head. Titanium is light, strong and a great conductor of heat and electricity. It is highly resistant to corrosion which makes it a ideal choice in the most harsh environment. It is widely used in aerospace, medical instruments, machinery and instruments, etc.
