Weld Nuts (DIN 929)

FULLERKREG DIN 929 hexagon weld nuts are manufactured to the Deutsches Institut für Normung standard across five material and strength grades. Unlike DIN 928 square weld nuts, DIN 929 features a hexagonal body with three weld projections, offering a more compact footprint and compatibility with standard hex tooling after welding. Designed for resistance (projection) welding onto sheet metal panels, these nuts deliver consistent, high-strength weld joints across a wide range of industrial applications. Available in stainless steel A2 and A4 for corrosion-resistant environments, and in low carbon or 10B21 boron alloy steel for high-volume industrial and structural welding. Metric sizes M3 through M12.

DIN 929 vs DIN 928 – How to Choose

Feature	DIN 929 (Hex Weld Nut)	DIN 928 (Square Weld Nut)
Body Shape	Hexagonal	Square
Weld Projections	3	4
Footprint	Compact	Larger bearing surface
Anti-rotation	Good (hex body)	Excellent (square body)
Post-weld tooling	Standard hex wrench compatible	Requires square socket
Typical Use	Compact panels, automotive trim	Structural sheet metal, heavy panels

Selection Guide

Grade / Material	Surface	Proof Load	Size Range	Best For
A2 / SUS304	Pickled & Passivated	A2-50	M3 – M12	General industry, food equipment, HVAC, electronics
A4 / SUS316	Pickled & Passivated	A4-50	M3 – M12	Marine, offshore, chemical, coastal outdoor, pharma
Class 4 / Q195	Bare (Plain)	310 MPa	M3 – M12	Automotive BIW, appliances, sheet metal (post-weld coated)
Class 8 / 10B21	Bare (Plain)	800 MPa	M3 – M12	Structural fabrication, heavy equipment, commercial vehicles
Class 10 / 10B21	Bare (Plain)	1000 MPa	M3 – M12	Safety-critical joints, cranes, mining, off-highway equipment

Standard Reference

DIN 929 specifies hexagon weld nuts with metric threads and three weld projections for resistance (projection) welding, issued by the Deutsches Institut für Normung (DIN). The hexagonal body allows post-weld access with standard hex tooling, making DIN 929 the preferred choice where compact geometry and tooling compatibility are required. FULLERKREG manufactures all DIN 929 variants in strict conformance with dimensional tolerances across the full material and strength range.
