NYLOC NUT ZINC METRIC

Zinc-plated nylon insert lock nuts, commonly referred to as nyloc nuts, are hex-shaped nuts used for secure fastening in assemblies subject to vibration or motion, where they prevent the nut from loosening. They are made from carbon steel and finished with a zinc coating for moderate corrosion resistance. 

Product Information & Key Features

Locking Mechanism: These nuts feature a durable nylon collar (insert) that deforms over the bolt thread during tightening, creating a high-friction fit that resists rotation and prevents the nut from backing off under load.

Material and Finish: They are primarily manufactured from high tensile carbon steel (often Class 8 or Class 10) and finished with a bright zinc plate for moderate corrosion protection. Zinc plating is a common, low-cost finish suitable for internal applications.

Performance: They are specifically designed for applications where vibration resistance is a key concern, such as in construction, automotive, and mechanical assemblies.

Usage Considerations: They are generally considered single-use items because the nylon insert's effectiveness is reduced once it has been deformed. They should not be used near heat sources where the nylon insert could deform permanently.
