304 stainless steel spring lock washer combination box with 900 pieces for metric bolts 2-12mm

This comprehensive 900-piece assortment of 304 stainless steel spring lock washers provides mechanics, engineers, and DIY enthusiasts with a complete range of sizes for professional-grade mechanical fastening applications. The combination box offers practical coverage of the most commonly used metric bolt diameters from 2mm to 12mm, making it suitable for automotive repair, industrial machinery assembly, electronic equipment manufacturing, and general hardware projects where reliable, corrosion-resistant fastening solutions are essential. With washers manufactured from AISI 304 stainless steel, this assortment delivers consistent performance in demanding environments where standard steel washers might corrode or degrade over time.

Features and Construction

This washer combination box is designed as a comprehensive hardware solution, containing 900 individual spring lock washers organised by size within a single storage container. The assortment provides immediate access to multiple washer dimensions without the need to purchase separate packs for different bolt sizes, offering both convenience and practical value for workshops, maintenance facilities, and serious DIY users who regularly work with metric fastener systems.

Material and Build

All washers in this assortment are manufactured from AISI 304 stainless steel, a chromium-nickel alloy known for its corrosion resistance and mechanical strength. This material composition makes the washers suitable for use in environments exposed to moisture, chemicals, or temperature variations where standard carbon steel washers might rust or degrade. The spring lock design incorporates a split-ring construction that creates consistent tension when compressed between fastener components, helping to prevent loosening from vibration or thermal cycling in mechanical assemblies.

Size and Practical Fit

The assortment covers a comprehensive range of metric bolt diameters from 2mm to 12mm, with corresponding inner diameters matching these standard sizes. Outer diameters range from 2.4mm to 13mm, providing sufficient bearing surface for various applications. Washer thicknesses span from 1mm to 6.2mm, offering different spring rates and tension characteristics to suit specific assembly requirements, from lightweight electronic components to heavier mechanical connections requiring greater locking force.

Uses and Placement

This washer assortment serves multiple applications across different technical fields, providing reliable fastening solutions wherever vibration resistance and secure connections are needed. The comprehensive size range and corrosion-resistant material make it equally suitable for professional workshop use and demanding home improvement projects requiring durable hardware components.

Event or Professional Use

In professional automotive repair and maintenance, these stainless steel spring washers provide reliable vibration resistance for engine components, suspension systems, and body panel attachments where constant movement could loosen standard fasteners. Machinery manufacturers and maintenance technicians use them in industrial equipment assembly to prevent bolt loosening from operational vibrations, while electronic equipment manufacturers employ them in chassis construction and component mounting where both electrical isolation and mechanical security are needed.

Everyday Home Use

For home workshop projects, these washers offer durable fastening solutions for bicycle repairs, furniture assembly, gate and fence construction, and appliance maintenance where outdoor exposure or occasional moisture contact occurs. DIY enthusiasts working on motorcycles, garden equipment, or outdoor structures benefit from the corrosion resistance when assemblies are exposed to weather elements, while hobbyists constructing models or technical projects appreciate the comprehensive size selection for various fastening requirements.

Benefits and Buying Value

This combination box delivers practical advantages through material quality, size completeness, and organisational convenience, providing users with immediate access to multiple washer sizes without separate purchases. The stainless steel construction offers long-term value by maintaining performance in conditions where standard hardware might deteriorate, reducing the need for frequent replacement of corroded components.

Reuse and Low Maintenance

The 304 stainless steel construction ensures these washers maintain their mechanical properties and appearance through multiple use cycles, as they resist surface corrosion and pitting that can affect reusability. When properly stored in the provided container between uses, the washers remain organised and protected from environmental contamination, ready for selection in future projects without degradation of their locking performance or material integrity.

Why Choose This Product

This assortment stands out for its comprehensive coverage of the most commonly used metric bolt sizes in a single organised package, eliminating guesswork and multiple purchases when working on projects requiring various fastener dimensions. The 304 stainless steel material provides a practical advantage over standard steel washers in applications where corrosion resistance matters, while the 900-piece quantity ensures sufficient supply for both current projects and future needs without immediate restocking concerns.
