Carbon Steel DIN929 M10 Weld Nut

Description:

Core Concept: Revolutionize your assembly process with this precision-engineered weld nut – designed to create permanent, high-strength threaded anchors in sheet metal where conventional fastening fails.

Engineering Excellence:

Optimized Projection Design: Three strategically placed welding nubs concentrate electrical current during resistance welding, ensuring consistent penetration and bond strength without warping thin materials (0.8mm+ recommended).

Material Integrity: Cold-forged carbon steel (Grade 4.8 or 8.8 available) provides superior tensile strength (≥400 MPa for Grade 4.8) and fatigue resistance versus stamped alternatives.

Dimensional Precision: Strict DIN 929 compliance guarantees:

True hexagonal profile (16mm across flats for M10)

Controlled projection height (0.4-0.6mm)

Accurate M10x1.5 thread tolerance (6g per ISO 965)

Unmatched Advantages:

Zero Backside Access Needed: Install threaded points in enclosed cavities or tight spaces.

Vibration Proof: Fusion-welded bond withstands extreme dynamic loads.

Production Speed: 3-5 second weld cycle vs. 30+ seconds for bolt-through solutions.

Material Savings: Eliminate reinforcement plates or thicker substrates.

Critical Application Scenarios:

Automotive BIW (Body-in-White): Seat brackets, ECU mounts, reinforcement panels

Industrial Machinery: Control cabinet backplanes, motor mounting plates, conveyor frames

Renewable Energy: Solar tracker joints, wind turbine enclosures

Mobile Equipment: Forklift mast assemblies, agricultural implement frames

Technical Notes:

Weld Parameters: Requires 8-12kA current @ 1.5-3V (adjust per material thickness)

Post-Process: Zinc plating (e.g. DIN 50961) or powder coating mandatory for corrosion protection

Compatibility: Pairs with ISO 4032 hex bolts or DIN 912 socket caps
