Product Features

✅ 304 Stainless Steel Material: Excellent corrosion resistance and heat resistance, strong rust prevention, no discoloration or oxidation after welding

✅ Internal Thread Design: Forms a permanent internal thread connection point after welding, facilitating subsequent bolt tightening, and allowing repeated disassembly and assembly without stripping.

✅ Multiple Welding Methods: Supports energy storage welding, spot welding, and seed welding processes, adaptable to various production equipment.

✅ Multiple specifications available: M3-M8 thread specifications × 4-30mm length, covering common application needs.

✅ Strong weld: Full-section weld bonding, achieving metallurgical bonding effect at the weld point, high connection strength, and not easily detached.

✅ Minimal heat-affected zone: Energy storage welding has a short discharge time (typically less than 20 milliseconds), resulting in minimal workpiece deformation and discoloration.

✅ Neat thread: Clear, burr-free threads with high concentricity, ensuring smooth installation.

✅ Multiple packaging options: 5/10/20/50 pieces available to meet different usage requirements.

Precautions

⚠️ When welding stainless steel, due to its high temperature strength, a higher electrode pressure is required compared to welding low-carbon steel.

⚠️ Welding current and energizing time need to be adjusted according to the plate thickness and nut specifications.

⚠️ Welding slag may remain in the threaded holes after welding; it is recommended to clean them with a tap.

⚠️ When welding 304 stainless steel, care should be taken to prevent intergranular corrosion and control heat input.

⚠️ Before purchasing, please confirm that the thread specifications and length match the installation requirements.
