SS Washer Types for Cookware and Industrial Use — Plain, Cup, Spring and Lock Washer
SS Washer Types for Cookware and Industrial Use — Complete Guide
A washer is a small component that makes a big difference. The right washer protects surfaces, distributes load, prevents loosening, and ensures your product assembly stays tight and professional. The wrong washer means failed joints, damaged surfaces, and customer complaints.
At Kamlesh Enterprises, Mumbai, we manufacture 5 types of washers for cookware manufacturers, industrial buyers, and utensil makers across India.
Type 1: SS Plain Washer (Flat Washer)
The most widely used washer in cookware manufacturing. A flat round disc with a central hole that distributes the load of a rivet, screw, or bolt over a larger surface — preventing the fastener from pulling through the material and protecting the surface finish.
Specifications: Material: SS 202/304 | ID: 3mm–15mm | OD: 6mm–30mm | Finish: Smooth
Applications: Pressure cooker handle assembly, fry pan riveting, sauce pan fitting, utensil manufacturing, general industrial fastening.
Type 2: SS Cup Washer
A cup-shaped washer with raised edges that cradles the fastener head and creates a neat, finished appearance. The cup shape locks the fastener position and adds a decorative element to the assembly — popular in visible cookware joints.
Applications: Visible handle riveting on premium cookware, decorative utensil assembly, anywhere a neat finished joint appearance is required.
Type 3: SS Spring Washer
A split helical washer that acts like a spring under compression. When a bolt or screw is tightened onto a spring washer, it bites into the mating surfaces and resists loosening caused by vibration, thermal cycles, and dynamic loads.
Specifications: Material: SS | Shape: Round split helical | Finish: Smooth
Applications: Industrial machinery, cookware assembly in high-vibration environments, automotive components.
Type 4: SS Spring Lock Washer
A heavy-duty locking washer with aggressive locking teeth or a helical split. Provides maximum resistance to fastener loosening under sustained load, vibration, and thermal cycling — essential for critical assembly applications.
Specifications: Material: SS | Thickness: 1mm–10mm | Packaging: Box | Price: ₹150–₹330/kg
Applications: Pressure cooker assembly, industrial machinery, cookware handle fittings requiring absolute security.
Type 5: Brass Washer
Made from high-quality brass for applications where electrical conductivity, machinability, or a specific material specification is required. Available in all standard sizes.
Specifications: Material: Brass | Shape: Round | Thickness: 1mm–10mm | Weight: 10g–50g | Price: ₹1–₹9/piece
Applications: Electrical connections, plumbing fittings, industrial machinery, applications requiring brass material.
