DIN127-B Grade 8.8 High Strength Spring Washers M3-M48

This DIN127‑B spring washer is made for fastening assemblies where ordinary flat washers may not provide enough resistance against loosening. The washer has a split ring structure with spring force. When compressed under a nut or bolt head, it helps maintain fastening pressure and supports a more secure connection.

The main listed grade is 8.8. Grade 8.8 spring washers are suitable for stronger fastening assemblies and are commonly used with industrial bolts and nuts in construction, machinery, equipment installation, and repair work. The washer should be selected together with the correct bolt size, nut specification, material, surface treatment, and working environment.

Material options include stainless steel and carbon steel. Stainless steel can be selected when better rust resistance or cleaner appearance is required. Carbon steel is suitable for general industrial fastening and cost‑effective bulk supply.The available surface colors are zinc white and black, helping buyers match the washer with zinc plated, black finish, or other compatible fastener assemblies.

The size range is M3‑M48. This covers common metric fastener applications, from small machinery and hardware components to larger construction and industrial fastening positions. The product is suitable for building, industry, machinery, equipment maintenance, steel components, brackets, frames, and general fastener distribution.

Material and Grade Explanation

The product is available in stainless steel and carbon steel. Stainless steel is suitable for applications requiring better corrosion resistance, clean appearance, and stable performance in general service environments. Carbon steel is widely used for industrial spring washers because it provides practical strength, elastic performance, and economical bulk purchasing.

The listed grade is 8.8. Grade 8.8 spring washers are suitable for high strength fastening assemblies and can be used with compatible bolts and nuts in machinery, construction, steel components, industrial equipment, and repair applications. Buyers should match the washer with the correct bolt grade, nut grade, tightening requirement, surface finish, and operating environment.

Surface Finish Options

Zinc white finish provides a clean silver‑white appearance and practical surface protection for general indoor and industrial applications. It is commonly used with zinc plated bolts, nuts, and hardware components.

Black finish is suitable for applications where a black appearance is preferred, such as machinery, equipment assembly, metal frames, and appearance‑matched fastener systems. The final finish should be selected according to corrosion resistance requirement, product appearance, storage environment, and assembly conditions.

DIN127‑B Spring Washer Design

DIN127‑B spring washers use a split ring structure. During installation, the washer compresses under the bolt head or nut and creates spring tension. This tension helps maintain pressure in the joint and improves resistance against loosening caused by vibration or movement.

This design is widely used in machinery, construction hardware, industrial repair, metal fabrication, and general fastening systems. Compared with a flat washer, a spring washer provides additional elastic locking support in suitable fastening positions.

Recommended Application Areas

Building Fastening: Suitable for construction hardware, brackets, plates, guardrails, pipe supports, steel members, and building maintenance.

Industrial Machinery: Suitable for equipment bases, machine frames, covers, motor mounts, support parts, and vibration‑prone assemblies.

General Hardware: Suitable for bolts, nuts, threaded rods, repair kits, maintenance stock, and mixed‑size fastener inventory.

Steel Components: Suitable for steel structures, metal frames, racks, supports, and industrial connection points.

Wholesale Supply: Suitable for fastener distributors, hardware wholesalers, machinery suppliers, project buyers, and bulk procurement orders.

Packaging and Supply

Packaging options include 25kg bags, 50kg bags, bags with pallets, 25kg cartons, cartons with pallets, and customized packaging according to customer requirements. Packaging can be selected based on washer size, quantity, transport method, warehouse handling, and export market needs.

The MOQ is 10000 pieces. Delivery can be arranged from Tianjin Port or Qingdao Port. Standard delivery can be arranged within about 15 days after deposit. If goods are in stock, delivery is generally 5‑10 days. If goods are not in stock, delivery is generally 15‑20 days depending on quantity and specification.
