The M8 Long Hex Nut is an extended hexagonal fastener designed for applications requiring deep thread engagement or coupling of threaded rods/studs. Its elongated body provides enhanced strength and versatility in mechanical assemblies.
Carbon Steel (Grade 4/8/10/12) with zinc plating (electro-galvanized) for corrosion resistance.
Optional stainless steel (A2/A4) for harsh environments.
Extended Length (typically 30–100mm for M8) for deeper thread engagement.
Hexagonal Head (13mm wrench size for M8) for easy installation.
Fully Threaded Interior ensures secure connections.
Complies with DIN 6334, ISO 4161.
Thread: M8×1.25mm (standard coarse pitch).
Construction: Scaffolding, steel structures.
Machinery: Equipment assembly, hydraulic systems.
Automotive: Suspension components, frame joints.
✔ High Load Capacity – Suitable for heavy-duty use.
✔ Space-Saving – Replaces multiple standard nuts in coupling applications.
✔ Corrosion-Resistant – Zinc plating protects against rust.
