Metric Washers

A standard flat washer for use in just about any assembly. A flat washers main task is to spread the load across a wider area, which comes in particularly useful when dealing with softer materials. Conforms to DIN 125. Please note that due to manufacturing limitations, all nylon variants of these items are only "similar to" and not "in absolute accordance with" the standard specified.

A thinner thickness flat washer. Produced To BS 4320.

A rarer design of flat washer with a slightly larger external diameter than a DIN 125 standard form A flat washer. To BS 4320.

Simple flat washer, similar to DIN 125 Form A type, but made to the newer ISO 7089 standard. Washers are used in nut and bolt assemblies to improve stress distribution on the bearing surface and span large clearance holes. These washers are as standard 200HV hardness grade suitable for hex head bolts, screws and nuts in property classes up to and including grade 8.8. They are also suitable for case-hardened thread rolling screws. Harder 300HV washers also available for use with hex head bolts, screws and nuts in property classes up to and including grade 10.9. They are also suitable for through hardened socket head cap screws, bolts and nuts.

Simple flat washer with a chamfered edge, similar to DIN 125 Form B type, but made to the newer ISO 7090 standard. Washers are used in nut and bolt assemblies to improve stress distribution on the bearing surface and span large clearance holes. These washers are as standard 200HV hardness grade suitable for hex head bolts, screws and nuts in property classes up to and including grade 8.8. They are also suitable for case-hardened thread rolling screws. Harder 300HV washers also available for use with hex head bolts, screws and nuts in property classes up to and including grade 10.9. They are also suitable for through hardened socket head cap screws, bolts and nuts.

Also known as a fender or repair washer, this very popular type offers a large external diameter. Often employed by plasterers, amongst others.

A large diameter washer where the external diameter is typically three times that of the nominal internal diameter. Also known as Form G, and complies with DIN 9021. Please note that due to manufacturing limitations, all nylon variants of these items are only "similar to" and not "in absolute accordance with" the standard specified.

A small diameter washer designed for use with screws with small diameter heads. To DIN 433.

A toothed or perforated washer usually employed in electrical connections such as battery terminals, but can also be used in assemblies to help prevent loosening. This variant includes teeth on the internal diameter, which leaves a neater finish. Accords with DIN 6798J.

A toothed or perforated washer usually employed in electrical connections such as battery terminals, but can also be used in assemblies to help prevent loosening. This variant includes teeth on the external diameter and therefore accords with DIN 6798A.

Spring washer designed to help prevent loosening of bolted joints under vibration. This type has a square section and is generally used with Socket Head Cap screws/bolts, manufactured to DIN 7980.

Spring washer designed to help prevent loosening of bolted joints under vibration. This type has a rectangular section and is generally used on hexagon head bolted fixings, manufactured to DIN 127.

Spring washer designed to help prevent loosening of bolted joints under vibration. This type is manufactured to DIN 6796 has an inherent conical shape. Also known as a Belleville washer, disc spring, coned-disc spring and cupped disc washer.

Wave profiled spring washer designed to help prevent loosening of bolted joints under vibration. To DIN 137.

Tab washers, also known as long tab wing washers are a type of locking washer, conforming to DIN 463. These washers have two tabs that can be folded around a bolt head or nut forming a mechanical locking solution between the bolt or nut and the ajoining surface. Used in situations where there is heavy vibration or in extreme heat conditions. The tab washer negates the need for a locking pin, castle or slotted nut.

Nord-Lock washers, also known as wedge-locking washers, secure bolts with tension instead of friction. Working as a pair, these washers create a wedge-effect underneath the bolt head or nut so that the joint is prevented from loosening unintentionally. Nord-Lock washers are quick and easy to install and remove, and they are reusable. Supplied as a glued pair, they are appropriate for use in vehicles, for DIY and for watersport equipment. Most sizes are available in two external diameters: the smaller standard type listed here, and the larger SP type.

Robust flat washer with a large square shape rather than the more usual round. Often used in timber construction and in applications at risk of seismic activity. To DIN 436.

Machined washer designed to accomodate a countersunk headed screw. Offers an attractive finish when employed. Please note that all dimensions are typical and are subject to variation between batches.

Conical Seat Washers manufactured to DIN 6319 D. Perfect for using in clamping solutions of non parallel surfaces in conjunction with Spherical Washers or hexagon nuts with spherical seating (DIN 6330).

Spherical Washers manufactured to DIN 6319 C. Perfect for using in clamping solutions of non parallel surfaces in conjunction with Conical Seat Washers.

These washers, as the name suggests, are used in heavy duty applications. Much thicker than other forms of equivalent nominal sizes, tough and corrosion resistant with a larger outer diameter. Manufactured to DIN 7349 and used with bolts with heavy type spring pins, where a larger bearing surface area is required.
