[25 PKG] Hex Lock Nuts Nylon Insert Low Carbon Steel Zinc DIN 985 M18-2.5

Hex Lock Nuts Nylon Insert Low Carbon Steel Zinc DIN 985 M18-2.5 are precision-engineered locking nuts designed to resist loosening in high-vibration assemblies. Made from low carbon steel with a durable zinc finish, these nuts incorporate a nylon insert that creates a strong friction lock as the bolt is threaded through, delivering secure clamping without the need for additional locking devices.

• Material: Low carbon steel with zinc plating for corrosion resistance
• Nylon insert: Integral locking element that provides vibration resistance
• Standards: DIN 985
• Size: M18-2.5 thread
• Finish: Zinc-coated
• Type: Hex lock nut with internal nylon insert

Key applications include machinery and equipment, automotive assemblies, agricultural machinery, construction hardware, and other threaded connections where vibration can cause loosening. The combination of a strong steel body, zinc finish, and nylon locking element makes these nuts ideal for reliable, maintenance-friendly fastening in demanding environments.

Installation is straightforward: thread onto a compatible bolt and tighten with a standard wrench. The nylon insert locks as the nut is torqued, helping prevent loosening under dynamic loads. For best results, follow typical torque guidance for M18 fasteners and avoid overtightening to preserve the locking action of the nylon insert.
