M16 Hot-Dip Galvanized Nyloc Lock Nut (FZV) DIN 985 – 35pcs

Description

The Hot-Dip Galvanized M16 Lock Nut (Nyloc) is a high-quality hex nut featuring an integrated plastic insert, specifically engineered to provide a permanent and extremely secure fastening solution in demanding environments. Manufactured to meet rigorous industry standards DIN 985 and ISO 7040, this nut combines a heavy-duty surface treatment with a reliable locking mechanism. It is the premier choice for heavy mechanical structures, machine components, and industrial installations where constant vibrations and harsh weather are part of the daily environment.

Smart Nyloc Mechanism Defies Vibrations

The secret behind the nut's superior performance is the captive nylon ring (plastic insert) located at the top collar of the internal thread:

• Vibration-Resistant: As the nut is threaded onto an M16 bolt, the bolt's threads cut into the unthreaded nylon insert. This creates a tight, high-friction interference fit that prevents the nut from backing off or loosening on its own—even under continuous mechanical stress, impacts, or severe vibrations.
• Hot-Dip Galvanized (HDG / FZV) for Extreme Environments: The nut has undergone a premium hot-dip galvanization process. This thick, durable zinc coating provides exceptional long-term protection against rust and corrosion, making the product perfectly suited for harsh outdoor climates, marine applications, and heavy-duty infrastructure projects.

Professional Grade for Industry and Construction

With an M16 thread profile, this lock nut is dimensioned for applications demanding immense tensile strength and structural integrity. It is designed to be paired with hot-dip galvanized bolts and threaded rods of matching dimensions. Please note that Nyloc-type lock nuts are primarily intended for single-use installation, as the nylon insert wears during removal, reducing its self-locking efficiency upon re-use.
