Product Description

Product Description

Carbon Steel/Stainless Steel Spring Washer

The spring washer, also known as a Belleville washer or split-ring washer, is a critical mechanical component designed to prevent fastener loosening in dynamic environments. Characterized by its helical or wave-shaped structure, it applies constant pressure between nuts and bolts through elastic deformation, creating friction to resist vibration and thermal expansion. Typically made of hardened carbon steel (e.g., DIN 127 standards) or stainless steel, it offers durability and corrosion resistance. Key features include a serrated edge for enhanced gripping and standardized dimensions (per GB/T 93-1987 and ISO 7359), ensuring global compatibility. Spring washers are widely used in automotive suspensions, machinery assemblies, electrical enclosures, and pipeline connections, where they compensate for material creep and maintain preload. When paired with flat washers, they balance pressure distribution and anti-loosening properties. Their versatility, cost-effectiveness, and ease of installation make spring washers indispensable in ensuring long-term structural integrity across industrial and consumer applications.

Packing & Delivery

Bulk/Fiber Bag/Neutral packing

Carton/Box

Wood Pallet/Box

Bagged packaging is ideal for smaller quantities of fasteners. The fasteners are placed in durable plastic bags, which are then sealed to protect the contents from moisture and dust. Each bag is clearly labeled with product details and quantities. This packaging is easy to handle and transport for smaller orders, making it convenient for workshops and retail settings.

Boxed packaging offers a more structured solution for medium to large quantities of fasteners. The fasteners are packed in sturdy cardboard boxes, which provide additional protection against physical damage during transit. The boxes are designed to stack neatly, optimizing storage space. Each box is labeled with essential information, ensuring easy identification and inventory 

Palletized packaging is used for bulk shipments of fasteners. Multiple boxes or bags are securely strapped onto a pallet, creating a stable and easily transportable unit. This method is highly efficient for large-scale distribution and warehousing. Palletized packaging ensures that large quantities of fasteners can be moved quickly and safely using forklifts, reducing handling time and labor costs.
