Washers
Rubber Washer
Rubber Washers are flexible sealing components designed to provide cushioning, vibration damping, and leak-proof fastening. They are available in a variety of rubber grades including natural, EPDM, nitrile, neoprene, silicone, and Viton. Manufactured to ASTM and DIN standards, they ensure durability and compatibility with diverse environments. Rubber washers are widely used in plumbing, roofing, automotive, machinery, and electrical applications. Their non-conductive and resilient properties make them ideal for sealing, insulation, and vibration control.
Spring Washer
Spring Washers are locking washers designed to apply spring force and prevent loosening of fasteners under vibration and load. They are manufactured in split, conical, heavy-duty, and wave designs for different applications. Produced to ASTM and DIN standards, they are available in multiple materials, hardness levels, and protective coatings. Their spring action ensures continuous tension in the joint, improving reliability in dynamic conditions. They are widely used in machinery, automotive, railways, structural assemblies, and electrical equipment.
Square Washer
Square Washers are flat washers with a square outer profile, providing a greater bearing surface than standard round washers. They are commonly used in timber construction, channel sections, and structural bolting applications. Manufactured to ASTM and DIN standards, they are available in multiple materials, sizes, and coatings. Their wide surface area prevents bolt heads and nuts from embedding into softer materials like wood. They are widely used in construction, railways, power transmission, and heavy structural assemblies.
Star / Serrated Washer
Star / Serrated Washers are locking washers with teeth or serrations designed to prevent loosening of fasteners under vibration and load. They bite into the surface of the assembly, creating additional friction and resistance to rotation. Manufactured to ASTM and DIN standards, they are available in internal, external, and combination serration types. These washers enhance joint security in dynamic or high-vibration environments. They are widely used in machinery, automotive, aerospace, electrical assemblies, and heavy engineering.
Taper Washer
Taper Washers are specialized washers designed to provide a level seating surface for bolts used on sloped flange beams and channels. They are manufactured to ASTM, DIN, and ISO standards in carbon steel, alloy steel, or stainless steel. The taper compensates for the slope of the flange, ensuring proper bolt alignment and full load distribution. Available in square and rectangular designs with galvanized, zinc plated, or stainless finishes, they ensure durability and reliability. They are widely used in structural steel construction, bridges, heavy equipment, and industrial machinery installations.
Tow Tongue Washer
Two Tongue Washers are mechanical locking washers with two tabs designed to secure fasteners against loosening under dynamic loads. They are manufactured to ASTM, DIN, and ISO standards in carbon steel, stainless steel, spring steel, or bronze. One tongue locks into a slot or keyway while the other is bent against a nut or bolt flat, creating a secure mechanical lock. Available in zinc plated, stainless, bronze, or phosphate finishes, they combine durability with corrosion resistance. They are widely used in automotive, railways, gear assemblies, machinery, and aerospace applications for reliable fastening security.
