The \u003cstrong\u003eWeld Nut A2\u003c\/strong\u003e DIN 929 in A2 \/ AISI 304 stainless steel is designed to provide long-lasting strength and corrosion resistance. It is easy to weld onto metal surfaces, creating a reliable connection that withstands mechanical stress and vibrations. The nut is ideal for both industrial and construction-related applications where a permanent attachment is required.\u003c\/p\u003e\n\u003ch2\u003eAREA OF USE\u003c\/h2\u003e\n\u003cp\u003ePerfect for weld mounting on machines, steel frames, building constructions, and equipment where permanent fasteners are needed. The weld nut is used to create a secure fastening point for screws and bolts and is easy to combine with standard tools during component assembly. Its corrosion resistance makes it suitable for both indoor and outdoor environments.\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL SPECIFICATIONS\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eProduct type:\u003c\/strong\u003e Weld nut\u003cbr\u003e\u003cstrong\u003eStandard:\u003c\/strong\u003e DIN 929\u003cbr\u003e\u003cstrong\u003eQuality:\u003c\/strong\u003e A2 \/ AISI 304 stainless steel\u003cbr\u003e\u003cstrong\u003eMaterial class:\u003c\/strong\u003e A2-70\u003cbr\u003e\u003cstrong\u003eThread type:\u003c\/strong\u003e Metric ISO thread\u003cbr\u003e\u003cstrong\u003eSurface finish:\u003c\/strong\u003e Untreated (natural stainless steel)\u003cbr\u003e\u003cstrong\u003eHead shape:\u003c\/strong\u003e Hexagonal\u003cbr\u003e\u003cstrong\u003eGrip type:\u003c\/strong\u003e External hexagon\u003c\/p\u003e\n\u003ch2\u003eFREQUENTLY ASKED QUESTIONS (FAQ)\u003c\/h2\u003e\n\u003ch3\u003eWhat characterizes a weld nut according to DIN 929 and how do the welding projections work?\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eDIN 929\u003c\/b\u003e specifies a hexagonal weld nut with three raised welding projections (weld points) on the underside:\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003ePrecise resistance welding:\u003c\/b\u003e The three welding projections concentrate the current and heat during spot welding or resistance welding.
