Value Collection 06WE External Tooth Lock Washer 6 Screw

Product Description

The VALUE COLLECTION 06WE is a 6 screw external tooth lock washer designed to prevent fastener loosening caused by vibration and torque in mechanical assemblies. Manufactured from Grade 2 spring steel with a zinc-plated finish, this washer provides reliable corrosion resistance and consistent locking performance in standard hardware applications. It measures 0.15 inches inner diameter, 0.32 inches outer diameter, and 0.022 inches thick, with a hardness rating of 40-50 HRC. Electricians, plumbers, HVAC technicians, and general mechanical trades use external tooth lock washers in panel, bracket, and equipment assembly work where fastener retention is critical.

This lock washer is suited for use with 6 size screws in residential and light commercial mechanical, electrical, and HVAC panel assemblies. The external tooth design bites into both the fastener bearing surface and the mating material, distributing load and resisting rotation under dynamic conditions. Typical applications include control panel assembly, equipment mounting, and structural bracket fastening where standard flat washers do not provide adequate vibration resistance.

Key Features

• External tooth design bites into fastener and mating surface to resist loosening under vibration
• Grade 2 spring steel construction with 40-50 HRC hardness for reliable locking force
• Zinc-plated finish provides corrosion resistance for standard indoor and light-duty applications
• 0.15 inches ID fits 6 screw fasteners; 0.32 inches OD distributes clamp load across the joint
• 0.022 inches thickness suits tight-clearance assembly locations

Compatibility

Designed as an OEM-style replacement and general-purpose lock washer for use with 6 size screws in mechanical, electrical, and HVAC assembly applications.

Installation Notes

External tooth lock washers are installed between the fastener head and the mating surface before the fastener is driven to final torque. Ensure the mating surface is clean and free of debris so the teeth can seat properly. Do not reuse a lock washer that has been fully compressed, as the teeth may no longer provide effective locking action. Installation should follow applicable NEC or equipment manufacturer fastener specifications for the assembly type.
