⚡ At a Glance
- • Holding Strength: Aluminium body combined with a nylon insert resists rotation and keeps threads secure
- • Best for: RC hobbyists, small-scale mechanical repairs and home DIY needing reliable M4 fastenings
- • Not ideal for: Heavy structural applications or jobs requiring larger thread sizes than M4
Aluminium alloy locknuts with a nylon insert supplied as a pack of ten M4 pieces. Designed to reduce loosening caused by vibration in hobby, vehicle and home uses.
Secure, vibration-resistant joints - with nylon-insert locking
Nylon seated into the nut grips the M4 thread, creating friction that resists rotation when exposed to vibration. The combination of metal body and polymer insert stabilises the threaded connection under repeated movement.
Less frequent re-tightening on moving parts such as RC bike pedals or lightweight vehicle fittings, keeping assemblies reliable during use.
Lightweight durability - with aluminium alloy construction
Aluminium alloy forms the nut body, offering a favourable strength-to-weight ratio while resisting everyday wear. The metal shell supports the nylon insert and preserves thread engagement without adding unnecessary mass.
Suitable for applications where added weight is a concern, such as hobby vehicles and moving components, while still providing dependable fastening.
Ready for quick maintenance - with a 10-piece multipack
Pack contains ten M4 locknuts, allowing immediate replacement or spares storage for routine upkeep. The multipack format simplifies small projects and intermittent repairs without sourcing individual items.
Convenient to keep on hand for routine maintenance, emergency swaps or batch assembly, reducing downtime during repairs.
