Low carbon steel black coating single head welding screw.
Welding screw is also called energy storage screw, electric bolt welding stud, or planting welding nail, etc.
coating is a unique industrial coating. The high-tech performance of coating can reduce product costs and improve production efficiency in many ways. It can also be used to directly solve product problems, thereby improving product quality and increasing sales.
coating is the originator of non-stick coatings. It combines heat resistance, chemical inertness, excellent insulation stability and low friction, and has comprehensive advantages that other coatings cannot compete.
has unique and excellent heat resistance (180～260℃), low temperature resistance (-200℃) and dielectric properties. It has the highest working temperature (260°C) and the best chemical stability. Except for molten alkali metals, high temperature and difluoride atmosphere, no other chemical substances can corrode it. It also has excellent weather resistance and can generally be used outdoors for 10 to 30 years. Has a low coefficient of friction, and its lubricity, especially self-lubricity is very good.
1. Partners provide drawings with 2D/3D files.
2. Partners provide samples, then our engineer will design the drawings.
1. Partners should pay sample fee for custom parts, aslo we return all sample fee when it reachesthe specified quantity.
2. Normally we make samples first to partners to check its quality, when they pass test then wefollow samples to mass production.
3. Usually there is 3-7days for samples production, and 15-25days for mass production.
