Understanding how important highly corrosion resistant fixings are above and below the waterline, UK-based Leyton Fasteners offers a huge range of A4-316 marine grade stainless steel fasteners – ideal for general use in marine structural applications – and Grade A2-304 for internal marine applications.
The standard A4-316 stainless steel alloy has been specifically manufactured so that, when exposed to harsh environments such as the ocean, the fastener won’t rust. Stainless steel bolts, screws and nuts can provide the best possible long-term corrosion resistance. For above the water line, Grade A2-304 will be sufficient but for anything that is to be submerged at least 6% molybdenum in the alloy is required such as A4-316.
“We recommend that stainless steel marine fasteners are not coupled with aluminium, because when stainless steel is in contact with aluminium, in the presence of an electrolyte saltwater, a galvanic corrosion process starts,” comments Nigel Fidler, managing director at Leyton Fasteners Limited. “The best way to avoid this is to keep stainless steel with itself and it will literally last a lifetime.”
Leyton’s range of marine products includes fasteners and fixings, chain, wire rope, hinges, pins, rings and much more. In addition to its standard ‘off the shelf’ range, Leyton Fasteners also offers a bespoke service to supply almost any fastener or fixing to customers’ specification, in a large variety of specialist materials specifically available for marine and offshore applications. These items can be produced to customer drawings from any material specification available from Leyton’s extensive range of alloys, brass, composites etc.
“We pride ourselves on our service. Our team has many years of expertise and experience in the world of fasteners, covering marine, engineering and associated industries. This is further enhanced by having access to an extensive range of contacts, resources, suppliers, and manufacturers, who we are in contact with daily to ensure that we supply quality products at competitive prices,” concludes Nigel.
