WASHERS
Washers are also used in conjunction with bolts and nuts to complete all assemblies, sometimes washers are just used to balance and take up excess space in the bolting process.
SAMPLE WASHERS WE CARRY
Melfast can furnish virtually any washers you can imagine. These are a sample of the kinds of washers we typically distribute
Flat Washer
A flat washer is typically used under the head of a nut or bolt in order to achieve a smooth-bearing surface. It is able to distribute the fastener load over a wider surface area or act as a spacer. Size wise, its outer diameter is often twice the width of its inner diameter. It is also often used in applications where strength is the main concern. Our corrosion resistant flat washers meet the DIN 125 specifications and can have a zinc-plated exterior finish for a more reflective appearance.
Split Lock Washer
Several industries and individuals count on our medium split lock washers for optimum performance in high stress applications. Formed in a range of materials, including graded steel, brass, aluminum, alloy and stainless steel, ask about medium split lock washers with durable platings. We carry copper plated, zinc plated, galvanized, cadmium and black oxide plated medium split lock washers for your application.
Bevel Washer
Beveled washers are required in applications involving American standard beams (those in an S shape). In order to comply with RCSC specifications regarding the slope between a bolt head or nut and the bearing surface, a beveled washer creates the proper slope to ensure safety and dependability. Available in steel, alloys and stainless, beveled washers come with and without plating.
Bonded Neoprene Washer
When your application requires an airtight seal between the fastener head and joining surface the bonded neoprene washer delivers. Manufactured with the highest grade of neoprene materials combined with standard steel or stainless steel, depending on your specifications. Ideal for water treatment, steel fabrication, pump manufacturing and the alternative energy industry, Melfast offers competitive prices and speedy delivery on quality bonded neoprene washers.
Rack Screw Shoulder Washer
Made from durable black nylon, our rack screw shoulder washers are built to hold up to serious load. Nylon does not corrode and requires no plating, but delivers impressive performance when coupled with a variety of screws and bolts. The rack screw shoulder washer starts as a pla
External Tooth Lock Washer
The popular external tooth lock washer is designed with teeth along the washer’s outer circumference, providing better gripping power when compared to the internal tooth lock washer. Designed to work well with soft surface applications, such as those involving plastics or aluminum, the external tooth lock washer can also be successfully used with hard surface applications in railroad construction, modular buildings, alternative energy and steel fabrication, among others. Available in steel and stainless steel, in diameters from #2 through to 1-inch.
Finish Cup Washer / Countersunk Washer
A must for many applications in electronics, woodworking, boat and furniture manufacturing, the finish cup washer creates a smooth finish while enhancing the holding power of the screw. Melfast offers finish cup washers in steel grade 2 SAE J429, as well as stainless steel 18-8 and brass. Platings include black oxide, zinc, nickel and passivate. Diameters available include #4 through to 3/8".
Internal Tooth Lock Washer
The internal tooth lock washer provides a tight fit and resistance to loosening in vibration. Manufactured of steel or stainless steel, internal tooth lock washers have teeth around the washer’s inner circumference, providing a more aesthetically pleasing look than the external tooth lock washer. This fastener has many applications in the steel fabrication industry, as well as in modular building, water treatment, renewable energy and railroad construction.
