Washers
Brass Washer
Brass Washers are non-magnetic and corrosion-resistant flat washers made from copper-zinc alloys. They provide excellent durability, electrical conductivity, and a polished decorative finish. Manufactured to ASTM and DIN standards, they are available in multiple grades, diameters, and thicknesses. Brass Washers are commonly used in plumbing, electrical fittings, marine hardware, and furniture assemblies. They are valued for both functional fastening support and their aesthetic appeal in visible applications.
Contact / Conical Washer
Contact / Conical Washers are specially designed spring-type washers that provide elastic force to maintain bolt tension under load. Their conical shape allows controlled deflection, improving the security of bolted joints against loosening. Manufactured to ASTM and DIN standards, they are widely used in heavy-duty and high-vibration environments. These washers ensure load distribution, prevent fatigue loosening, and enhance joint reliability. They are commonly used in structural steelwork, railways, wind turbines, automotive, and heavy machinery.
EPDM Bonded Washer
EPDM Bonded Washers are sealing washers combining a metal backing with an EPDM rubber layer for watertight fastening. They provide load distribution from the metal side while the EPDM side compresses to create a durable weatherproof seal. Manufactured to ASTM and DIN standards, they are available in carbon steel, stainless steel, and aluminum versions. These washers are resistant to UV, ozone, and weathering, making them ideal for outdoor use. They are widely used in roofing, cladding, metal buildings, and applications requiring leak-proof fastening.
Flat Washer
Flat Washers are the most common type of washer, designed to distribute the load of a threaded fastener evenly across a surface. They prevent damage to the mating surface, reduce wear, and provide a smooth bearing area for nuts and bolts. Manufactured to ASTM and DIN standards, they are available in various sizes, thicknesses, and materials. Flat washers are versatile and used across mechanical, structural, electrical, and decorative applications. They are essential in construction, automotive, machinery, and general engineering projects.
Hardened Washer
Hardened Washers are heat-treated flat washers designed to distribute load and prevent embedding under high-strength bolts and nuts. They are manufactured to ASTM F436 and DIN 6916 standards for use with structural and heavy-duty fasteners. The hardened surface ensures durability, resistance to wear, and consistent torque during tightening. Available in flat, beveled, and oversized types, they meet the demands of structural steel connections. They are widely used in bridges, buildings, machinery, and heavy structural assemblies.
Hillside Washer
Hillside Washers are specially beveled washers used on angled or sloped surfaces to provide a flat bearing surface for nuts and bolts. They allow bolted joints to be tightened securely where members are not parallel, such as in hillside, sloped, or pipe connections. Manufactured to ASTM and DIN standards, they are available in carbon steel, stainless steel, and galvanized finishes. Their beveled design ensures proper load distribution and prevents bolt bending or uneven stress. They are commonly used in transmission line construction, pipe supports, structural bracing, and slope-mounted assemblies.
Nail Washer
Nail Washers are oversized washers designed to be used with nails or screws for fixing sheets, roofing panels, and cladding. They spread the load over a wider area, preventing sheet damage and pull-through during fastening. Manufactured to ASTM and DIN standards, they are available in flat, domed, or rubber-sealed types. Their large OD and optional sealing liners provide strength and weatherproofing for outdoor applications. They are widely used in roofing, cladding, timber construction, and light structural projects.
Nord Lock Washer
Nord-Lock Washers are wedge-locking washers designed to secure bolted joints against loosening from vibration and dynamic loads. They work in pairs with cam faces and serrations that create tension, making loosening impossible without deliberate unfastening. Manufactured to DIN 25201 standards, they are available in steel, stainless steel, and specialized alloys. These washers maintain preload and reliability even in extreme vibration or thermal cycling conditions. They are widely used in wind energy, railways, mining, construction, heavy equipment, and automotive industries.
Nylon Teflon Washer
Nylon and Teflon Washers are lightweight, non-metallic washers designed for insulation, sealing, and anti-friction applications. Nylon washers provide electrical insulation and wear resistance, while Teflon washers offer excellent chemical resistance and low friction. Manufactured to ASTM and DIN standards, they are available in multiple sizes, thicknesses, and material grades. They are ideal for applications requiring non-corrosive, non-magnetic, and lightweight fastening solutions. Commonly used in electrical equipment, plumbing, aerospace, chemical plants, and precision engineering.
Penny Washer
Penny Washers are large-diameter flat washers designed to spread the load of a fastener over a wider surface area. They are ideal for use with thin sheet materials, wood, and soft substrates where load distribution is critical. Manufactured to ASTM and DIN standards, they are available in a wide range of materials, diameters, and finishes. Their oversized design reduces the risk of pull-through and enhances fastening stability. They are commonly used in construction, carpentry, automotive, and general engineering applications.
Picot Washer
Picot Washers are locking washers with serrated or toothed edges designed to prevent loosening of fasteners under vibration and dynamic loads. They are manufactured to ASTM, DIN, and ISO standards in carbon steel, stainless steel, spring steel, or brass. The serrated teeth bite into the surface, providing a secure grip and enhanced load distribution. Available in internal, external, and heavy-duty variants with multiple coatings, they ensure durability and resistance to vibration loosening. They are widely used in automotive, machinery, aerospace, electronics, and general engineering applications.
Quick Lock Washer
Quick Lock Washers are advanced locking elements designed with wedge-locking action to prevent loosening of bolted joints under vibration or shock. They are manufactured to ASTM, DIN, and ISO standards in hardened steel, alloy steel, or stainless steel. The dual-washer design creates opposing wedge angles with serrated surfaces, ensuring the bolt remains secure even under extreme dynamic loads. Available with zinc flake, stainless, or black oxide finishes, they provide high corrosion resistance and long service life. They are widely used in railways, wind turbines, heavy machinery, automotive, and critical safety applications where bolt loosening is unacceptable.
