GB15856.1 304SS Pan Head Cross Self Drilling Screw
1.Products Details:
These screws can directly penetrate materials and form threads without pre - drilling, thanks to their specially designed tips that can drill like a drill bit, and the threads can cut materials to form internal threads during the screwing process. This greatly simplifies the installation steps and improves work efficiency.
2.Key Features:
High Strength:Made of high - quality steel and processed by heat treatment and surface treatment, cross - recessed pan - head self - drilling screws have high strength and hardness, and can bear large tensile and shear forces.
Self - drilling and Self - tapping Function:These screws can directly penetrate materials and form threads without pre - drilling, which greatly simplifies the installation steps and improves construction efficiency. The self - drilling ability comes from the special design of the tip, which can drill holes like a drill bit, and the thread design can cut materials to form internal threads during the screwing process.
Excellent Corrosion Resistance:The surface of the screws is galvanized or treated with other anti - corrosion methods, which has good corrosion resistance and can be used for a long time in humid or corrosive environments.
Convenient Installation:The pan - head is designed with a cross - recessed, which can be tightened with a screwdriver or an electric wrench, and the installation is convenient and fast.
Stable Torque Transmission:The cross - recessed pan - head structure provides more stable torque transmission and centering effect during assembly, ensuring the precise docking of the connected parts and long - term stable performance.
Wide Application:It can be used for fixing various materials, such as wood, plastic, metal, etc., and is widely used in many industries, including machinery manufacturing, electronic and electrical, building decoration, etc., with strong versatility and adaptability.
Good Space Efficiency:Compared with some traditional screws, the design of cross - recessed pan - head self - drilling screws is relatively compact. After installation, it does not occupy too much space, which is beneficial to space utilization, especially in some occasions where space is limited.
