304 Stainless Steel Spring Lock Washer Combination Box with 900-Piece Assortment

This 900-piece combination box provides a comprehensive range of 304 stainless steel spring lock washers, designed for users who need a versatile selection of fasteners for maintenance, repair, and assembly work. The assortment eliminates the need to purchase multiple small packs of individual sizes, offering a practical solution for workshops, garages, and DIY enthusiasts. The washers are made from 304 stainless steel, a material chosen for its resistance to rust and corrosion in many environments, making it suitable for both indoor and outdoor applications where moisture or exposure could be a concern. The set is organised within a single box, helping to keep your fastener inventory tidy and easily accessible for various projects, from automotive and bicycle repairs to securing furniture and appliances.

Features and Construction

This product is defined by its material composition and the range of sizes included in the assortment. The following details cover the construction and the practical fit of the washers within the set.

Material and Build

The washers are fabricated from 304 stainless steel. This austenitic steel alloy contains chromium and nickel, which contribute to its general corrosion resistance and non-magnetic properties. This makes it a suitable choice for applications where exposure to water, humidity, or mild chemicals could cause standard carbon steel washers to rust. The spring lock design features a single cut and helical form, which allows the washer to exert a spring force when compressed between a nut and a surface, helping to maintain clamping pressure and resist loosening caused by vibration or thermal cycling.

Size and Practical Fit

The assortment is defined by several key dimensional ranges. The inner diameter, which must fit over the bolt shaft, spans from 2 to 12. The applicable diameter for the bolt is similarly stated as 2 to 12. The outer diameter of the washers ranges from 2.4 to 13, which determines the contact area and load distribution. Finally, the thickness of individual washers varies from 1 to 6.2, influencing the spring force and stack height. This combination of ranges means the set can accommodate a variety of bolt sizes and application requirements, though the specific quantity of each exact size within the 900-piece total is not detailed.

Uses and Placement

The primary function of a spring lock washer is to prevent fastener loosening. This assortment supports a wide spectrum of uses, from professional mechanical work to common household tasks.

Event or Professional Use

In mechanical, automotive, and engineering contexts, these washers are used to secure nuts on engines, machinery, vehicle components, and structural assemblies subject to vibration. The 304 stainless steel construction makes them suitable for marine fittings, food processing equipment, or outdoor structures where corrosion resistance is beneficial. The range of sizes allows a technician to select the appropriate washer for M2 to M12 bolt sizes (approximate metric equivalents), making it a useful general-purpose kit for workshop benches and service vehicles.

Everyday Home Use

For DIY projects and home maintenance, these washers can be used to secure nuts on bicycles, garden furniture, shelving units, play equipment, and appliances. The anti-loosening feature helps maintain the integrity of assembled items over time. Having an assortment on hand means that when a repair or assembly project arises, the correct size washer is likely available without a special trip to the hardware shop, saving time and effort on common household fixes.

Benefits and Buying Value

The value of this product lies in its practicality, reusability, and the convenience of having a broad selection in one purchase.

Reuse and Low Maintenance

Stainless steel washers are durable and can often be reused if removed carefully and are not deformed. Their corrosion resistance means they are less likely to seize or fuse to bolts, simplifying disassembly for future adjustments or repairs. The material itself requires no specific maintenance or protective coating, maintaining its function with simple cleaning if it becomes dirty.

Why Choose This Product

This combination box is chosen for its comprehensiveness. Instead of buying individual packs and potentially ending up with unused surplus or missing a needed size, this 900-piece assortment covers a wide spectrum. The 304 stainless steel material offers a practical upgrade over plain steel for many applications where rust is a concern. The organised box keeps all components together, reducing loss and clutter compared to loose washers, making it a efficient addition to any toolkit for someone who regularly engages in mechanical or DIY work.
