Flat washer YATO YT-06871, copper, 150 pcs

Flat copper washers YATO YT-06871, pack of 150 pieces. These flat washers are manufactured from copper to provide good electrical conductivity, corrosion resistance and a soft bearing surface. They serve as spacers, seals or load-distributing elements beneath fasteners in electrical, plumbing and mechanical repair, assembly and maintenance tasks. The set contains multiple identical washers, suitable for repetitive use or bulk projects where consistent copper contact is required.

Advantages

Copper construction ensures reliable electrical conductivity and natural resistance to corrosion in many environments. The soft metal surface reduces the risk of damage to mating parts and creates a better seal under bolts and screws compared with harder materials. A bulk pack of 150 pieces simplifies inventory management for workshops and maintenance teams and reduces the need for frequent reordering.

Suitable for

• Electrical connections and grounding where conductive washers are needed
• Plumbing fittings and sealing applications requiring a malleable seal
• Mechanical assemblies that need load distribution under fasteners
• Repair, maintenance and renovation projects with repeated use of identical washers

Key specifications

• Material: copper
• Form: flat washer (plain ring)
• Quantity: 150 pieces per pack
• Typical uses: electrical conductivity, sealing, load distribution

How to use

Select washers of the correct inner and outer diameter to match the fastener and the hole. Place the copper washer between the fastener head or nut and the mating surface to improve load distribution and, when required, to provide a conductive or sealing interface. For sealing applications, tighten the fastener to the appropriate torque to deform the washer slightly and form a secure contact without over-compressing the copper. For electrical or grounding use ensure clean contact surfaces free of paint or oxidation to maintain conductivity.

Usage recommendations

Store washers in a dry environment to limit surface oxidation. When used in corrosive environments, consider suitable protective measures or periodic inspection. Verify washer dimensions against fasteners before installation to ensure proper fit and function.
