304 Stainless Steel Spring Lock Washer Combination Box with 900-Piece Assortment from M2 to M12

This comprehensive washer set provides a practical solution for maintaining secure connections in applications prone to vibration and movement. The 900-piece assortment covers a wide range of common fastener sizes from M2 to M12, making it suitable for automotive repairs, machinery maintenance, and general DIY projects. Manufactured from 304 stainless steel, these washers offer corrosion resistance that helps maintain their appearance and function in various environmental conditions. The spring lock design creates consistent tension against nuts and bolts, helping prevent loosening over time without requiring specialised tools or complex installation procedures.
Features and Construction

The washer combination box includes a carefully selected range of sizes to accommodate most common fastener requirements. Each component is designed with practical application in mind, focusing on reliable performance and easy identification within the organised storage case.
Material and Build
All washers in this set are manufactured from 304 stainless steel, a material choice that provides resistance to rust and corrosion. This makes the washers suitable for use in environments where moisture or exposure to elements might be a concern, such as automotive underbody applications or outdoor equipment. The spring lock design incorporates a slight helical twist that creates tension when compressed between fastener components, actively working against vibrational forces that could otherwise lead to loosening over time.
Size and Practical Fit
The assortment covers inner diameters from 2mm to 12mm, corresponding to fastener sizes M2 through M12. Outer diameters range from 2.4mm to 13mm, providing adequate bearing surface for various applications. Washer thickness varies from 1mm to 6.2mm across the size range, with thicker washers typically corresponding to larger diameter sizes. This dimensional range allows users to select appropriate washers for everything from small electronic repairs to larger mechanical assemblies without needing multiple specialised sets.
Uses and Placement

The spring lock washer combination box serves multiple purposes across different sectors, from professional workshops to home garage projects. Its comprehensive size range and corrosion-resistant construction make it adaptable to various scenarios where reliable fastening is required.
Event or Professional Use
In professional automotive or machinery maintenance contexts, this washer set provides quick access to appropriate sizes for vibration-prone applications. The stainless steel construction maintains performance in environments where lubrication, cleaning chemicals, or moisture exposure might compromise other materials. The organised storage system helps maintain workshop efficiency by keeping washers sorted and accessible, reducing time spent searching for specific sizes during repair or assembly procedures.
Everyday Home Use
For DIY enthusiasts and home maintenance projects, the 900-piece assortment offers versatility for various tasks around the house. From securing furniture components that experience movement to maintaining garden equipment or bicycle repairs, having multiple sizes readily available simplifies project completion. The corrosion resistance means washers can be used in damp environments like bathroom fixtures or outdoor furniture without concern for rapid deterioration, while the spring lock design helps maintain tightness in applications where regular adjustment would be inconvenient.
Benefits and Buying Value

Choosing this washer combination box provides several practical advantages over purchasing individual sizes or smaller sets. The comprehensive assortment and durable construction offer long-term value through reduced need for additional purchases and reliable performance across various applications.
Reuse and Low Maintenance
The 304 stainless steel construction supports repeated use across multiple projects, as the material maintains its properties through installation and removal cycles. Unlike some coated or plated alternatives, the stainless steel doesn't require special care to preserve surface treatments, and any cleaning needed can be accomplished with common workshop materials. The organised storage case helps prevent loss and mixing of sizes, extending the useful life of the set by keeping components accessible and identifiable for future projects.
Why Choose This Product
This combination box offers a practical balance between comprehensive size coverage and organised storage. The 900-piece assortment provides more versatility than smaller sets while remaining manageable in a single case, avoiding the clutter of multiple containers. The spring lock design addresses a specific fastening challenge – vibration-induced loosening – with a mechanical solution that doesn't require adhesives, special tools, or complex installation procedures. For users needing reliable fastening across various applications, this set provides a single-source solution with the material durability to support long-term use.
