Value Collection 742106PS M10 Internal Tooth Lock Washer

Product Description

The VALUE COLLECTION 742106PS is an M10 internal tooth lock washer designed to maintain fastener tension and resist loosening under vibration. The washer features inward-facing teeth that bite into both the mating surface and the fastener head, creating a secure mechanical lock. Manufactured from Grade 2 spring steel with a zinc-plated finish for corrosion resistance, this washer measures 10.5mm inside diameter and 18.0mm outside diameter with a 0.9mm thickness. It is suited for general-purpose fastening applications in mechanical assembly, electrical enclosures, HVAC equipment panels, and light industrial installations where fastener retention is required.

This internal tooth lock washer fits M10 fasteners and is appropriate for use in residential and commercial mechanical assemblies, electrical panel construction, HVAC unit fabrication, and similar trade applications. The internal tooth design is preferred when a clean outer edge is needed, such as in electrical grounding connections or finished panel assemblies. Technicians and assemblers in HVAC, electrical, and plumbing trades use this style of lock washer as a standard hardware component during equipment assembly, field repair, and panel work.

Key Features

• Internal tooth design bites into fastener bearing surface to resist rotational loosening
• Grade 2 spring steel construction provides consistent tension and rebound under load
• Zinc-plated finish offers corrosion protection for general indoor and sheltered applications
• 10.5mm inside diameter sized for M10 screws and bolts
• 0.9mm thickness suitable for standard M10 fastener stack-ups

Compatibility

Designed as an OEM-style replacement or standard hardware component for use with M10 fasteners in general mechanical, electrical, and HVAC assembly applications.

Installation Notes

Install between the fastener head and the mating surface with the teeth facing the fastener bearing surface. Ensure the mating surface is clean and free of coatings that would prevent tooth engagement. Torque the fastener according to the equipment manufacturer or applicable code requirements. Single-use installation is recommended, as re-torquing a used lock washer may reduce locking effectiveness.
