About this item
- ✅ Self locking nuts are engineered to prevent bolts and threaded rods from loosening under vibration, a constant in maintenance and repair workshops. They enable you to clamp and secure a wide variety of components. Thanks to their high-tensile steel construction, they deliver outstanding strength for both indoor and outdoor applications.
- ✅ Locknuts are widely used to secure bolt and nut connections. Common applications include mechanical engineering, automotive, motorcycle servicing, model construction, fence building, furniture assembly and electro-mechanical or light industrial uses such as cars, aviation, railways, refrigeration, lifts, switches, instruments, décor, machinery and electronics.
- ✅ These insert lock nuts are crafted from 100% galvanised steel, offering high corrosion resistance compared to regular steel finishes. Compliant with DIN 985, each unit incorporates an integrated nylon insert that provides reliable anti-vibration locking.
- ✅ Package comprises 10 × M20 hex nuts to DIN 985, internal thread, 20 mm height, 30 mm spanner size. This locking nut for bolts is essential for professional fastening tasks, ensuring optimal assembly even in confined spaces and reliable long-term component joining. The hexagonal shape guarantees secure spanner engagement and accurate torque application.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
