Description

Spring Washers are used as a means of creating tension during tightening in order to help keep the nut from working loose later. They are a low cost option. Also known as a lock washer or split lock washer
Understanding and measuring washer sizing: Washer sizes can be a little confusing so we will do our best to try to make it a little easier to understand. When searching for a washer, firstly, let's say you have a M6 bolt and you want a matching washer, look for washers with M6 at the beginning of the description (you can speed this up by using our "shop by" filters). If you already have a washer and you are trying to match it, measure the inside, then look for a size slightly smaller that your measurement. For example the inside measurement of the washer you measured is approx 6.50mm, you need to look for a M6 washer. If the washer measured 17.25mm internally then you need a M16 Washer. Remember washers are not precision fasteners and variations in sizing do exist and all measurements on our site should only be used as a guide
Are Metric & Imperial Washers Interchangeable?: In most cases they are which is why we have added metric sizing to the imperial range and imperial sizing to the metric range. If you are still unsure or if the washer dimensions are critical click on the washer you are interested in and view the technical specifications table before ordering
Material / Coating: Marine Grade Stainless Steel A4-70 G316 is the ultimate corrosion resistance fastener. Designed to be used in all conditions. It is the best material to use in marine, coastal, chemical and food environments. Stainless steels are largely non-magnetic, but it is not uncommon for some stainless steel fasteners, especially stamped components like washers to show a small degree of magnetism. This is partly due to the work-hardening of the product during the manufacturing process. Marine Grade Stainless Steel A4-70 G316 can be easily identified by the following markings: A4, A4-70, A4-80, 316 or G316. Small sized washers are generally not stamped
Can Stainless corrode?: Stainless steel is corrosion-resistant but not corrosion-proof and corrosion can occur if the material is installed or handled incorrectly. The use of tools and drills made from conventional steel during the installation of stainless steel fasteners may also lead to problems. Even the hardest of tools can produce debris that leaves minute steel particles on the stainless steel fastener surfaces or in pre-drilled holes. It is these particles that often rust when exposed to moisture or oxygen and can result in a stained or tarnished finish to the stainless steel material
Measurements: Every effort has been made to ensure all measurements on our site are accurate and where possible to the relevant standard, however they should only be used as a guide. If you have an exact requirement or you see a problem with our specifications please contact us directly
Dimensions: Our stock is sourced from various suppliers, differences can exist such as the inside dimension, outside diameter, thickness, visible stamped markings, appearance and actual finish
Photos: represent the product, not the size. Our title has industry sizing but if additional information is required refer to the CAD drawing, Specifications Table or Technical Specifications PDF
