RS PRO Bright Zinc Steel Locknut M12, Nylon Insert, Grade 8 Steel, DIN 6926 275-642

RS PRO 275-642 Bright Zinc Steel Locknut is a high-quality fastening solution, specifically engineered for demanding environments where vibration and stress may lead to traditional fastener loosening. Manufactured from grade 8 carbon alloy steel, this locknut features a bright zinc-plated finish for extended durability and resistance to corrosion. The M12 metric size offers compatibility with a wide range of mechanical assemblies, while the integrated nylon insert provides a self-locking mechanism, ensuring that the nut remains securely fastened even under severe dynamic loads.

This locknut is distinguished by its hexagonal structure, which allows for straightforward application and removal using standard hand tools such as spanners or sockets. An integrated flat washer-style flange helps distribute clamp loads evenly, preventing damage to softer materials like plastics or wood and improving joint stability.

Compliant with DIN 6926 standards, the RS PRO 275-642 locknut meets stringent quality requirements for industrial fasteners. It is ideal for securing components in machinery, automotive assemblies, and domestic appliances where reliable fastening in the presence of vibration is critical. The bright zinc finish provides environmental protection, making the nut suitable for both indoor and outdoor use.

Applications include assembly in industrial equipment, automotive engine and chassis systems, as well as domestic white goods such as washing machines and dryers. The nylon insert is designed for single-use longevity; repeated removal and reinstallation may reduce its effectiveness as a self-locking feature.
