500-Piece Black Nylon Plastic Gasket Washer Assortment for Metric Bolts and Screws M2 to M10

When working on small repairs, electrical enclosures, or automotive fittings, having a selection of non-conductive washers on hand can save time and frustration. This 500-piece assortment covers eight common metric sizes from M2 through M10, providing flat sealing washers for a wide range of bolt and screw diameters. Made from black nylon, these gaskets offer electrical insulation and resistance to corrosion, making them suitable for use in dry indoor environments, electronics, and general mechanical assembly. The set is organised by size in a compact storage box, so you can find the right washer quickly without sorting through loose pieces.

Features and Construction

Each washer in this kit is moulded from nylon plastic with clean edges that sit flat against surfaces. The assortment is divided into eight sizes, all with inner diameters matching standard metric bolt gauges. Outer diameters and thicknesses vary proportionally to provide adequate bearing surface and spacing.

Material and Build

Nylon is a lightweight synthetic polymer that does not rust or corrode in normal conditions. It also acts as an electrical insulator, which is useful when fastening components in electronic devices or power supplies. The washers are formed without burrs or sharp edges, reducing the risk of scratching painted or sensitive surfaces during installation.

Size and Practical Fit

The kit includes 100 pieces each of M2 (5 mm OD, 1 mm thick), M2.5 (5 mm OD, 1 mm thick), and M3 (6 mm OD, 1 mm thick) washers for small fasteners. For medium bolts, there are 50 pieces each of M4 (8 mm OD, 1 mm thick), M5 (10 mm OD, 1 mm thick), and M6 (12 mm OD, 1.2 mm thick). Larger applications are covered by 40 pieces of M8 (16 mm OD, 1.4 mm thick) and 10 pieces of M10 (20 mm OD, 2 mm thick). This graded distribution means you have more of the commonly used small sizes and fewer of the larger ones, matching typical usage patterns.

Uses and Placement

The assortment is designed for light to medium-duty applications where a plastic washer is preferred over metal. Common uses include spacing and sealing in electrical equipment, general hardware assembly, and hobby or model making.

Event or Professional Use

Technicians and electricians can keep this kit in a service van or workshop for installing panels, terminal blocks, and junction boxes. The insulated washers help prevent galvanic corrosion between dissimilar metals and reduce the risk of short circuits in low-voltage wiring.

Everyday Home Use

Around the house, these washers are useful for fixing furniture, fitting handles, assembling shelving brackets, or repairing small appliances. The metric sizing means they work with the majority of standard European and Asian bolts found in flat-pack furniture and imported devices.

Benefits and Buying Value

Buying a single multi-size assortment is often more convenient than sourcing individual packs of each size. This set provides a broad range of the most common metric washer dimensions, all in one box.

Reuse and Low Maintenance

Nylon washers are not intended for single-use applications; they can be removed and reinstalled multiple times as long as they are not deformed or damaged. The material does not absorb moisture in normal indoor conditions, so the washers remain dimensionally stable for repeated use.

Why Choose This Product

The main advantage is the combination of quantity, size range, and organised packaging. With 500 pieces across eight sizes, you are likely to have the right washer for most small metric fasteners without needing to visit the hardware store. The compact box keeps everything tidy, and the separate bags make it easy to refill your working stock.
