RS PRO Bright Zinc Steel Nylon Insert Locknut DIN 985 M16 24mm Width 10.50mm Height 122-4376

RS PRO 122-4376 is a bright zinc-plated steel nylon insert locknut manufactured to DIN 985 standards. It is engineered for mechanical fastening applications where resistance to vibration and secure locking is critical. The nut's nylon insert compresses during bolt engagement, creating a firm lock that helps maintain assembly integrity even under severe vibration.

The locknut is manufactured from mild steel grade 8.8 with a bright zinc finish that provides excellent corrosion resistance and compatibility with a range of industrial environments. The high-quality nylon insert helps seal the bolt threads, preventing ingress of water, oil, and other fluids that might otherwise cause thread corrosion or failure.

This locknut is rated to retain its locking capability at temperatures up to 250°C, making it suitable for demanding environments. It also offers resilience against various chemicals including organic acids, solvents, oils, and mineral salts, ensuring long-term reliability in diverse industrial conditions.

The product features a 24 mm width across flats and an overall height of 10.50 mm. It is commonly used by builders, joiners, roofers, and DIY enthusiasts for secure fastening applications requiring vibration resistance and sealing capabilities.

The locknut is made from mild steel grade 8.8 with a bright zinc finish providing corrosion resistance. It features a nylon insert which compresses upon bolt insertion, locking the nut securely. Retains locking ability up to 250°C ensuring durability in high-temperature environments.

Provides resistance against organic acids, solvents, oils, and mineral salts protecting the thread. Offers a 360° seal that prevents leaks of water, oil, and other liquids. Complies with DIN 985 standard ensuring industrial quality and consistency.

This locknut variant is available in sizes from M5 to M20, providing options for various mechanical and construction applications. If bright zinc plating is not suitable, stainless steel options in A2 and A4 are also available for enhanced corrosion resistance.
