About this deal

Expander System is an award-winning patented solution with over one million systems installed since 1985. A permanent solution to lug bore wear that doesn’t require special skilled technician. All washers are laser marked with brand name, control number and type code for increased traceability down to the raw material in the factory. This increased surface area spreads the force (and hence the tension load) that is applied over a much greater area when the nut is tightened, making them ideal for use on weak or damaged surfaces. Heavy Flat Washers are used to increase the bearing surface of a nut or fastener's head thus spreading the clamping force over a larger area. They can be useful when working with soft materials and oversized or irregular shaped holes. The washer also ensures a smooth base for the nut to press against. Boltight Typhoon+ tensioners are our secure bolting solutions that have been developed to meet the technical and environmental demands of the wind energy market.

High performance and dedication to safety are in our DNA. The fact that we are the only company to offer CE marked securing washers is proof. The following table shows the exact dimensions of all our Form A & BWashers (don’t forget to make an allowance for the 1mm +/- tolerance in diameter as stated above). Often called penny washers or mudguard washers, repair washers have an overall outside diameter that is larger than standard flat washers.

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 Use the Expander System as a lug wear repair solution for an easy, cost effective and permanent repair method, provided to over 2 million customers globally.

As with all of our fasteners, please note that it is the responsibility of the user to assess the suitability of the product in question. FORM A & B WASHERSForm C washers have a slightly large overall diameter than Form A & B washers, as you can see by comparing the same sized washer in the table below. This means that they are particularly suitable for use with materials that are softer than hard metal (such as wood and plastic), as they give a wider spread of load and reduce the potential for damage. When it comes to flat washers, the good news is that regardless of where you buy them or who makes them, the dimensions should be almost exactly the same. This is because all metric flat washers are classed within certain Forms, and each form has the same dimensions regardless of manufacturer.
