304 Stainless Steel Spring Lock Washer Assortment Box: 900PCS for M2 to M12 Bolts

This 900-piece combination box offers a practical and organised solution for securing fastenings against vibration. It contains an extensive assortment of spring lock washers manufactured from 304 stainless steel, a material chosen for its reliable resistance to rust and corrosion. The kit is designed to cover a broad range of common bolt sizes, with inner diameters precisely spanning from 2mm to 12mm to fit bolts from M2 through to M12. With outer diameters ranging from 2.4mm to 13mm and thicknesses from 1mm to 6.2mm, this collection provides the necessary components for various assembly, repair, and maintenance tasks where a secure, long-lasting fastening is required without the need for multiple separate purchases.

Features and Construction

This product is defined by its comprehensive specification range and material choice, providing a versatile fastening aid. The construction centres on the functional properties of 304 stainless steel and the precise dimensional grading of the washers themselves.

Material and Build

Every washer in this 900-piece assortment is made from 304 stainless steel. This alloy is widely used in fasteners due to its chromium-nickel content, which forms a passive layer that resists oxidation and staining. This makes the washers suitable for use in damp environments, outdoors, or in applications where appearance and material longevity are considerations. The spring lock design incorporates a helical cut with raised ends, which applies a continuous spring force against the nut and workpiece to help maintain clamping pressure.

Size and Practical Fit

The assortment is systematically organised by size to aid selection. The core specification is the inner diameter, which ranges from 2mm to 12mm. This corresponds directly to an applicable bolt diameter range of 2mm to 12mm (metric sizes M2 through M12). The accompanying outer diameter range, from 2.4mm to 13mm, ensures an adequate bearing surface for distribution of load. Furthermore, the washers are available in thicknesses from 1mm to 6.2mm, allowing for selection based on the gap to be filled or the specific spring tension desired for a given application.

Uses and Placement

The spring lock washer assortment serves a fundamental mechanical role in preventing the loosening of bolted joints. Its utility spans from casual DIY projects to more demanding professional settings where vibration is a concern.

Event or Professional Use

In professional workshops, manufacturing, or vehicle maintenance, this assortment allows mechanics and technicians to quickly find the correct washer size for repairs and assemblies on machinery, electrical enclosures, or structural frameworks. The 304 stainless steel construction is particularly relevant for marine applications, food processing equipment, outdoor fixtures, or any scenario where corrosion could compromise joint integrity or contaminate a process. The organised box minimises downtime spent searching for components.

Everyday Home Use

For home DIY enthusiasts, this box provides a ready supply of washers for securing furniture, fixing bicycles, assembling shelving units, or repairing garden tools. The anti-vibration characteristic of the spring lock design is beneficial for items like washing machines, lawnmowers, or decking where movement is constant. Having a range of sizes on hand means most common household fastening jobs can be completed correctly without a special trip to the hardware shop.

Benefits and Buying Value

Purchasing this assortment box translates to convenience, readiness, and material suitability for a wide array of tasks, representing a practical approach to fastener management.

Reuse and Low Maintenance

The 304 stainless steel construction supports reuse; washers can often be used multiple times if not overtightened or damaged. Their corrosion resistance means they are less likely to seize or fuse to bolts, making disassembly cleaner and easier. Maintenance is minimal—keeping them in their supplied box protects them from dirt and mixing with other items, preserving their organisation and condition for future use.

Why Choose This Product

This product is chosen for its clear specifications: a 900-piece count covering a defined and useful size range (M2 to M12), all made from a specified material (304 stainless steel). It eliminates guesswork by providing the exact inner diameter, outer diameter, and thickness measurements. The combination box format offers better value and efficiency compared to buying individual packs of washers for each specific size needed, making it a cost-effective and time-saving resource for anyone who regularly works with fasteners.
