304 Stainless Steel Spring Lock Washer Combination Box with 900PCS Covering M2 to M12 Metric Sizes

This comprehensive spring lock washer set provides 900 pieces of 304 stainless steel fasteners in a range of metric sizes suitable for automotive, machinery, and home DIY applications. The combination box includes washers with inner diameters from 2mm to 12mm, corresponding to common bolt sizes from M2 through M12. Each washer features the characteristic spring lock design that creates tension to prevent loosening under vibration, making them particularly useful for moving machinery components, automotive assemblies, and equipment subject to regular movement or vibration. The 304 grade stainless steel construction offers corrosion resistance without additional coatings, suitable for various environmental conditions where rust prevention is important.

Features and Construction

The spring lock washer combination set is designed as a practical solution for workshops, garages, and home toolkits needing a range of washer sizes without purchasing individual packs. The 900-piece quantity provides multiple washers across the size spectrum, reducing the need for separate purchases when working on projects requiring different fastener diameters.

Material and Build

Manufactured from 304 grade stainless steel, these washers provide inherent corrosion resistance compared to standard steel variants that may require plating or coating. The spring lock design features a split-ring construction that applies consistent pressure against both the fastener head and work surface. This tension-based locking mechanism works by creating friction that counteracts rotational forces from vibration or movement, helping to maintain fastener tightness over time without requiring additional locking compounds or devices.

Size and Practical Fit

The washers cover inner diameters from 2mm to 12mm, corresponding to metric bolt sizes M2 through M12. Outer diameters range from 2.4mm to 13mm, providing adequate bearing surface for various applications. Thickness varies from 1mm to 6.2mm across the size range, with thicker washers generally provided for larger diameter applications where greater spring force may be required. The size progression allows users to select appropriate washers for everything from small electronic repairs using M2 fasteners to automotive and machinery applications requiring M12 bolts.

Uses and Placement

The spring lock washer combination set serves multiple applications across mechanical, automotive, and household repair contexts. The range of sizes makes it suitable for both professional workshop environments and DIY home projects where having various washer dimensions available improves efficiency and reduces downtime searching for specific components.

Event or Professional Use

In professional automotive repair, machinery maintenance, and equipment assembly contexts, these washers provide vibration-resistant fastening for components subject to movement or oscillation. The 304 stainless steel construction makes them suitable for environments with moisture exposure where corrosion could compromise standard steel washers. The comprehensive size range allows mechanics and technicians to address multiple repair scenarios without maintaining separate inventories for each washer size, while the spring lock design helps maintain assembly integrity in vehicles, industrial equipment, and machinery with moving parts.

Everyday Home Use

For home DIY projects, the combination box offers a convenient assortment for furniture assembly, appliance repair, bicycle maintenance, and general household fixes. The spring lock feature proves particularly useful for items like washing machines, lawnmowers, power tools, and outdoor equipment that experience vibration during operation. Home users benefit from having multiple sizes available when working on projects with mixed fastener requirements, eliminating trips to hardware stores for individual washers. The corrosion resistance also makes these washers suitable for bathroom fixtures, outdoor furniture, and garden equipment exposed to moisture.

Benefits and Buying Value

The spring lock washer combination box delivers practical advantages through its comprehensive size range, material properties, and functional design. Rather than purchasing separate packs for each required size, users obtain 900 pieces covering the most common metric dimensions in a single package.

Reuse and Low Maintenance

304 stainless steel washers can typically be reused multiple times when removed carefully with appropriate tools. The corrosion-resistant properties mean they maintain their appearance and function even after exposure to moisture, unlike plated steel washers that may corrode if the plating becomes damaged. The included gasket tools facilitate proper installation and removal, helping to preserve washer integrity during maintenance cycles. This reusability contributes to long-term value, particularly in workshop environments where components may be disassembled and reassembled during repair processes.

Why Choose This Product

This combination set addresses the common frustration of not having the right size washer available during repairs or assembly projects. The 900-piece quantity across the M2 to M12 size range provides coverage for most common metric fastener applications in one purchase. The spring lock design offers functional advantage over flat washers by helping prevent fastener loosening, while the 304 stainless steel construction provides corrosion resistance without additional treatment. The inclusion of gasket tools completes the package for proper installation and removal, making it a comprehensive solution for both professional and DIY users seeking reliable fastening components.
