1,Description:
Welding screws usually refer to two things: one is fasteners specially designed for welding (such as welding nails, welding screws), and the other is the operation method of fixing ordinary screws to workpieces by electric welding process. Which one to choose depends on whether you want to purchase finished products or do the welding and repair yourself.
Which screws can be welded directly:
The common welded fasteners on the market mainly include welded studs and types of welded screws . One end of them is a thread and the other end is a welding surface, which can be directly welded to the steel plate with a special welding machine. The materials include low-carbon steel, 304 stainless steel, aluminum alloy, etc. The diameters range from M3 to M20, and the lengths are generally between 12 and 200 millimeters. Anchor bolts also fall into this category and are often used for fixing building steel structures. They need to be pre-embedded or welded onto the base plate.
This UNF 10-32 copper weld screw with bright polished surface is a precision conductive fastener tailored for laboratory testing equipment and electronic control module production, adopting high-purity oxygen-free copper material to ensure ultra-high electrical conductivity and stable signal transmission performance. The UNF fine thread American standard design features dense and precise threads, which can realize ultra-fine locking and positioning for miniature electronic control modules and high-precision laboratory testing equipment, avoiding assembly gaps and loose positioning. The surface undergoes professional bright polishing treatment to remove surface burrs, oxide layers and processing traces, presenting a smooth and flat mirror surface effect. The polished treatment not only enhances the surface aesthetics and wear resistance, but also avoids surface impurity interference affecting electrical signal transmission and equipment detection accuracy. The copper material has excellent thermal conductivity, which can quickly dissipate local heat generated by electronic module operation and prevent equipment overheating failure. The product has precise welding size and small welding deformation, which will not affect the precision parameters of laboratory testing instruments during welding assembly. It is widely used for internal circuit connection, component fixing and conductive assembly of industrial control modules, experimental detection equipment and precision electronic devices, providing high-precision and high-stability fastening and conductive solutions for electronic manufacturing and laboratory testing industries.
3,Technical Advantages
Hot-dip Yellow Zinc Plated Mild Steel composition: 0.15%-0.20% low carbon iron steel, surface thick yellow chromate zinc passivation layer. Material maintenance rules: Economical anti-rust coating for indoor pump use; wipe workshop oil mist attachment regularly; avoid long-term immersion in running water; store finished bolts in moisture-proof carton; tighten bolts regularly to compensate vibration loosening; re-spray zinc anti-rust paint for surface scratch positions to prolong service life.
Available in small packing, carton packing, or pallet configurations to meet your shipping and storage requirements.
Manufactured by JIA SHAN Hardware Company with strict quality control measures and pre-shipment inspection.
