Metric Washers

The Westfield Fasteners range of metric washers is presented below. Each item is typically available in either box or sachet quantity for despatch from our warehouse today. Metric washers are designed to be used in conjunction with the equivalent sized metric bolts, screws and nuts.
Material Key
A2
A2 Stainless Steel - also known as grade 304 or 18/8. A general purpose grade of stainless steel.
A4
A4 Stainless Steel - also known as grade 316 or 18/8/3. A higher corrosion resistant, marine grade of stainless steel.
Alum
Aluminium - Alumium is a lightweight, strong and corrosion resistant material. As the temperature lowers, aluminium actually increases in strength. It is also non-magnetic, carries a current and does not spark easily.
BRASS
Brass - offers an attractive, corrosion resistant finish.
Bronze
Phosphor Bronze - normally used in conjunction with brass fasteners.
BZP
Bright Zinc Plated (BZP) Steel - non-stainless standard steel grade offering a basic level of corrosion resistance.


BZP
300HV

Bright Zinc Plated (BZP) Steel with 300HV hardness - non-stainless standard steel grade offering a basic level of corrosion resistance, but with 300HV hardness.
Copper
Copper Alloy - Copper has good corrosion resistance and high tensile strength, allowing it to withstand high-pressure and high temperature conditions. It is a highly ductile and malleable material, enabling copper washers to create tighter seals and withstand vibration better than steel. Copper also provides excellent thermal and electrical conductivity.
Duplex
Duplex Stainless Steel 1.4462 - a type of stainless steel, which has greater corrosion resistance than A4 / 316 and a high tensile strength of minimum 700 N/mm2. Also known as 318LN.
Nylon
Plastic (Nylon Polyamide) - a tough lightweight plastic, strong at low temperatures, with excellent resistance to chemicals, and features favourable sliding friction behaviour.
ZnFlk
Zinc Flake coated steel - Coated with superior mechanically applied zinc lasting 480 hours in the salt spray test.


ZnFlk
300HV

Zinc Flake coated steel with 300HV hardness - Coated with superior mechanically applied zinc lasting 480 hours in the salt spray test, and with 300HV hardness.
