[1000 BULK] Hex Lock Nuts Nylon Inserts Steel Zinc 3/8-16

Hex Lock Nuts Nylon Inserts Steel Zinc 3/8-16 are precision fasteners designed to provide reliable, vibration-resistant threading in a variety of applications. Featuring a steel hex nut with a molded nylon insert, these Nylock nuts are ideal for automotive, machinery, and equipment assemblies where standard nuts may loosen over time.

• Self-locking nylon insert creates friction under vibration, helping prevent loosening without requiring extra washers or coiling springs.
• Durable steel construction with a durable zinc finish offers good corrosion resistance for everyday use in challenging environments.
• Size and threading specified as 3/8-16 UNC, ensuring compatibility with standard bolts and threaded rods.
• Uniform hex profile provides easy wrench access and even torque distribution for secure fastening.
• Versatile applications suitable for automotive, industrial equipment, outdoor gear, and general machines where vibration resistance is required.

Materials and finish combine to deliver dependable performance: steel core with a zinc plating and a molded nylon insert that provides long-lasting locking action. The combination reduces maintenance and simplifies assembly in both new builds and repairs.

Install with standard hand tools to finger-tight and then tighten to the appropriate torque for your hardware specification. For best results, consult your equipment’s torque chart and ensure proper alignment before final tightening.
