Au-ve-co Products 3975 Washer Lock Nut 3/8-24 Thread

Product Description

The AU-VE-CO PRODUCTS 3975 is a zinc-plated spring steel washer lock nut designed for use with threaded fasteners requiring a 3/8-24 thread size. The integrated washer face distributes clamping load and the spring steel construction provides consistent locking tension to resist loosening from vibration and torque. Width across flats measures 9/16 inches, conforming to standard inch-series fastener geometry. Licensed plumbers, HVAC technicians, electricians, and mechanical contractors commonly use this nut when securing components in vibration-prone assemblies or where fastener retention is critical to system integrity.

This washer lock nut is suited for residential and light commercial mechanical applications where threaded fasteners must maintain clamp load under dynamic or vibrating conditions. Typical install scenarios include securing hardware to panels, brackets, housings, and mechanical assemblies across HVAC, plumbing, and electrical trades. The zinc finish provides basic corrosion resistance appropriate for interior and protected-exterior environments. Sold individually per package; minimum order quantity is 100 units.

Key Features

• 3/8-24 inch-series thread size for compatibility with standard unified fine-thread fasteners
• 9/16 inch width across flats fits standard hex tooling
• Spring steel construction delivers reliable locking tension under vibration
• Zinc-plated finish provides corrosion protection in interior and sheltered environments
• Integrated washer face distributes bearing load and reduces surface damage

Compatibility

Designed for use with threaded fasteners in inch-series mechanical assemblies requiring a 3/8-24 washer lock nut.

Installation Notes

Install using a standard hex wrench or socket sized to 9/16 inches across flats. Ensure mating fastener threads are clean and free of debris before assembly. Follow applicable mechanical and trade codes for proper fastener torque sequencing. Inspect the spring steel locking feature for deformation before reuse, as lock nuts subjected to high torque cycles may not retain full locking performance if reused.
