[25 PKG] Hex Lock Nuts NU Nylon Inserts 18/8 Stainless 3/8-16

Hex Lock Nuts NU Nylon Inserts 18/8 Stainless 3/8-16 combine the reliability of a standard hex nut with the locking action of a nylon insert. Made from 18/8 stainless steel, these nuts resist corrosion in harsh environments while the nylon insert prevents loosening under vibration, delivering secure fastening in demanding applications.

Key Features

• Material: 18/8 stainless steel for excellent corrosion resistance and durability in outdoor, marine, and industrial settings.
• Locking Mechanism: Nylon insert (NU) creates friction against the bolt threads to resist loosening from vibration and dynamic loads.
• Thread Size: 3/8-16 (UNC), standard coarse thread for widely used fasteners.
• Style: Hex lock nut design provides easy wrench access and a secure fit.
• Finish: Natural stainless finish with corrosion protection.

Specifications

• Thread: 3/8-16
• Material: 18/8 stainless steel
• Insert: Nylon (NU)

Applications

Ideal for automotive, marine, machinery, construction, and outdoor assemblies where vibration is a concern and corrosion resistance is essential. The combination of stainless steel and nylon insert makes these nuts suitable for environments exposed to moisture, salt, and temperature variations.

Installation & Care

• Use standard wrenches to tighten onto a 3/8-16 bolt.
• Avoid overtightening to prevent unnecessary wear on the nylon insert.
• Inspect the nylon insert for wear or damage; replace if the locking action diminishes.
• Clean surfaces before installation to ensure a proper lock and prevent contamination.
