M8 rubber flat washers — 120 pack

This pack contains 120 black rubber flat washers sized for M8 fasteners. Each washer has an 8 mm inner diameter, a 16 mm outer diameter and a 2.2 mm thickness. They suit home installations, household appliances and garden watering accessories where bolted connections need sealing or cushioning.

Flexible rubber construction

The washers are made from flexible rubber that resists high temperature, wear and corrosion while providing strong sealing and electrical insulation. Rubber conforms to harder or irregular surfaces more effectively than metal, giving reliable sealing in water, oil and air applications. The material also cushions fasteners, reducing pressure and friction on delicate parts such as nylon or glass.

Check fastener size and surface before ordering

Verify that your bolts or screws match the 8 mm inner diameter so the washer seats correctly. Ensure the 16 mm outer diameter fits within the available clearance on the joint. Confirm the 2.2 mm thickness suits the required clamping force and sealing gap. The rubber is intended for general sealing and cushioning; it is not rated for specialised chemical or extreme-pressure environments.

Questions about this item

What inner diameter does the M8 rubber washer have, and which bolt size does it match?

The washer has an 8 mm inner diameter, matching M8 bolts with a .31 inch clearance.

What are the outer diameter and thickness that determine whether it fits my flange or housing?

The outer diameter is 16 mm (.63 inch) and the thickness is 2.2 mm (.09 inch), so check your counterbore depth and flange width.

How do I install the washer correctly, and what common mistake should I avoid?

Place the flat rubber washer between the bolt head or nut and the mating surface, then tighten; the common error is using a washer with the wrong inner diameter, which prevents proper sealing.
