Value Collection 741046PS M2 External Tooth Lock Washer

Product Description

The VALUE COLLECTION 741046PS is an M2 external tooth lock washer designed to prevent fastener loosening under vibration and dynamic loads. Made from Grade 2 spring steel with a zinc-plated finish, this washer features an external tooth configuration that bites into both the mating surface and the fastener bearing face to resist rotation. The inside diameter measures 2.2mm, the outside diameter measures 4.5mm, and the thickness is 0.3mm. It is a standard hardware component installed by maintenance technicians, millwrights, and assembly professionals across mechanical, electrical, and light structural applications.

This external tooth lock washer is suited for use with M2 screws in compact fastening assemblies where space is limited and vibration resistance is required. Typical applications include small appliance assembly, electronic enclosures, HVAC control panels, and light-duty mechanical subassemblies. The zinc plating provides basic corrosion resistance in indoor and moderately protected environments. This part does not meet military specifications and is intended for general commercial and industrial use. Sold individually, with a minimum order quantity of 200 pieces.

Key Features

• External tooth design grips both fastener and mating surface to resist loosening under vibration
• Grade 2 spring steel construction provides reliable elasticity and holding force
• Zinc-plated finish offers basic corrosion protection for indoor applications
• Inside diameter of 2.2mm matches M2 screw shank sizing
• Thin 0.3mm profile suits compact, space-limited fastening assemblies

Compatibility

Designed for use with M2 fasteners in general commercial and industrial fastening applications.

Installation Notes

Install this lock washer between the fastener head and the mating surface with the teeth facing the mating surface for maximum grip. Ensure the mating surface is clean and free of coatings that could reduce tooth bite effectiveness. Do not reuse lock washers after removal, as the teeth may be deformed and holding force will be reduced. No special tools are required beyond standard hand or power drivers appropriate for the M2 fastener being used.
