Products

Malaxy weld nuts (welding nuts) are precision-engineered fasteners designed for permanent attachment to metal surfaces through resistance projection welding or spot welding processes. Once welded, they become an integral part of the assembly, providing durable, high-strength threaded anchor points where traditional nut-and-bolt fastening is impractical—particularly on thin-gauge sheet metal, hard-to-reach blind applications, or structures where backside access is unavailable.

Key Features & Benefits

• Permanent metallurgical bond — Welding fuses the nut’s projections with the base metal, delivering vibration-resistant, high-strength threads that outperform loose nuts and clips in dynamic environments.

• Single-side installation — Eliminates the need for backside access, reducing assembly labor and simplifying production in automotive chassis, enclosures, and structural assemblies.

• Self-locating projections — Precision-machined pilot bosses and raised projections ensure accurate alignment during automated welding, delivering repeatable joint quality for high-volume manufacturing.

• High torque resistance — Hex and flange weld nuts withstand greater tightening torque than standard nuts, making them ideal for heavy-duty bolted connections that demand clamp-load retention.

• Weld-through friendly materials — Manufactured from weldable-grade low carbon steel (1008/1010), stainless steel (304/316), and alloy steel, with optional zinc-plating for enhanced corrosion resistance.

• Wide compatibility — Suitable for projection welding, spot welding, MIG, and TIG processes, accommodating both automated production lines and manual fabrication shops.

Materials & Strength Grades

Common Applications

Weld nuts are widely adopted across global manufacturing industries due to their reliability, permanent retention, and single-side installation capability. Typical applications include:

• Automotive & Commercial Vehicles — Chassis frames, body-in-white (BIW) construction, seat structures, suspension systems, engine mounts, and battery tray assemblies for EVs.

• Heavy Equipment & Construction Machinery — Structural steel frameworks, crane components, agricultural implements, and mining equipment requiring vibration-resistant threaded points.

• Sheet Metal Fabrication — Enclosures, electrical cabinets, HVAC units, solar panel mounting frames, and industrial racking systems.

• Aerospace & Transportation — Equipment mounts, interior non-critical structures, and railway carriage assemblies (subject to engineering approval).

• Appliances & White Goods — Refrigerator compressor mounts, washing machine chassis, oven frames, and other sheet-metal assemblies requiring permanent threads.

• Furniture Manufacturing — Metal furniture joints, table legs, chair frames, and modular shelving systems.
