The M3 x 10mm Metal Washer is a flat, circular fastening accessory designed to be used with M3 screws, bolts, and nuts. It features an inner diameter suitable for M3 fasteners and an outer diameter of approximately 10mm. Washers play an important role in mechanical assemblies by distributing the load of a fastener over a larger surface area, helping to prevent damage to the material being fastened.
Manufactured from durable metal materials such as stainless steel, zinc-plated steel, or other corrosion-resistant alloys, the M3 x 10mm washer offers excellent strength, durability, and wear resistance. Its simple yet effective design improves fastening reliability and helps maintain secure connections even in applications subject to vibration or repeated use.
The washer is commonly used in electronics, robotics, machinery, automotive assemblies, furniture construction, and DIY engineering projects. By increasing the contact area between the fastener and the mounting surface, it reduces the risk of deformation, cracking, or pull-through of softer materials such as plastic, wood, and thin metal sheets.
