M12 Hot-Dip Galvanized Nyloc Lock Nut (FZV) DIN 985 – 100pcs

Description

The Hot-Dip Galvanized M12 Lock Nut (Nyloc) in a highly cost-effective bulk pack of 100 pieces is a professional-grade hex nut featuring an integrated plastic insert. It is specifically engineered to provide a permanent, vibration-proof, and corrosion-resistant fastening solution. Manufactured in strict compliance with industry standards DIN 985 and ISO 7040, this bulk pack is the optimal choice for workshops, construction sites, and industrial series manufacturing where high volume and component reliability are vital.

Effective Vibration Defense with Nyloc Insert

The lock nut is equipped with an internal, gripping nylon ring (polyamide) located at the top collar of the hex nut that functions as a mechanical thread-locking device:

• Vibration-Resistant Locking: As the nut is threaded onto an M12 bolt or threaded rod, the bolt's threads force their way and compress into the unthreaded nylon insert without cutting the material away. This generates high radial friction that prevents the nut from backing off or loosening on its own under dynamic loads, severe shaking, or mechanical impacts.
• High-Quality Hot-Dip Galvanization (HDG / FZV): Through hot-dip galvanization, the nut receives a thick, heavy-duty zinc layer that provides uncompromising defense against rust. This ensures the joint maintains its full structural integrity over long lifespans, even in harsh and humid outdoor environments, marine applications, and agricultural or infrastructure projects.

Professional Grade Bulk Packaging

This 100-pack of M12 lock nuts (Property Class 8) is perfectly suited for larger projects requiring extreme material availability and assembly efficiency. The nut is ideally paired with hot-dip galvanized screws, bolts, and threaded rods of matching M12 dimensions. Please note that nylon-insert lock nuts should generally be considered single-use components in safety-critical assemblies, as the plastic ring deforms during removal and loses part of its self-locking capability upon re-use.
