SS Spring Washers

Flat Washers

1) Purpose and Utility:

Flat washers are the most commonly used washers, designed to evenly distribute the load of a bolt, screw, or nut as the fastener is tightened.

2) Material and Standards:

Manufactured in materials like stainless steel (Standard: ASTM A240) and carbon steel (Standard: ASTM A36), ensuring durability and corrosion resistance.

3) Application Diversity:

Used in construction, automotive, and manufacturing industries for their ability to provide a larger bearing surface, thereby reducing stress on the fastened material.

Cup Washers

1) Design and Functionality:

Cup washers feature a cup-like form, allowing the head of the fastener to fit snugly. This design creates a flush finish with the fastener head, typically used with wood screws.

2) Material and Quality:

Available in materials like brass (Standard: ASTM B16) and steel (Standard: ISO 898-1), chosen for their strength and aesthetic appeal.

3) Industry Usage:

Commonly utilized in carpentry, furniture making, and interior design for their ability to provide an attractive and finished appearance.

Spring Washers

1) Locking Mechanism:

Known as locking washers, spring washers are designed to prevent bolts, screws, or nuts from vibrating loose.

2) Material and Compliance:

Constructed from spring steel (Standard: DIN 127B) to ensure elasticity and strength.

3) Vibrational Applications:

Ideal for use in machinery, automotive applications, and electronics where vibration might loosen fasteners over time.

Repair Washers (Penny/Fender Washers)

1) Enhanced Bearing Surface:

Repair washers, often called penny or fender washers, are crafted to create a larger bearing surface and prevent pull-through.

2) Material and Durability:

Typically made from galvanized steel (Standard: ASTM A153) for corrosion resistance and increased strength.

3) Versatile Use:

Suited for repair work, particularly in scenarios where there's a need to cover oversized holes or distribute the load over a larger area, such as in automotive and construction industries.
