In the demanding world of hardware and construction, especially in the export-driven markets of the UAE, how do you ensure that critical components like benjo washers remain reliable over time? These small but vital fasteners are essential for securing structures, yet the harsh UAE climate—with its high humidity, extreme heat, and saline air—poses a significant threat to their integrity. Proper storage isn’t just a recommendation; it’s a necessity to avoid costly replacements and project delays.
Benjo washers, also known as spring or disc spring washers, provide axial flexibility and tension in bolted joints, compensating for thermal expansion, vibration, and load changes—common challenges in UAE construction. Their ability to maintain preload under dynamic conditions makes them indispensable, but only if they are stored correctly to prevent degradation before use.

How It Is Made: From Raw Material to Finished Product
Raw Material(s): Benjo washers are primarily manufactured from high-carbon steel or stainless steel, chosen for their strength and durability. In corrosion-prone environments like the UAE, stainless steel variants (e.g., 304 or 316 grades) are preferred due to their enhanced resistance to rust.
Manufacturing Process: The production involves several key stages: First, raw steel is cold forged or stamped into disc shapes using precision dies. This is followed by heat treatment—quenching and tempering—to achieve the desired spring properties. The washers are then often coated or plated (e.g., with zinc or cadmium for additional corrosion resistance) and subjected to surface finishing to ensure smooth edges and consistent dimensions.
Key Properties Derived from Manufacturing: The heat treatment process imparts essential properties like high hardness and spring tension, allowing the washer to absorb shocks and maintain load under stress. Coating stages enhance corrosion resistance, critical for longevity in humid and saline conditions.
Quality Control: Manufacturers conduct rigorous checks, including dimensional accuracy measurements, hardness testing (e.g., Rockwell scale), salt spray tests for corrosion resistance, and visual inspections for defects like cracks or uneven coatings, ensuring compliance with standards such as ISO 9001.
Essential Uses in the UAE Construction Landscape
Primary Application(s): In UAE construction, benjo washers are widely used in structural steel connections, machinery installations, and HVAC systems, where they prevent loosening due to vibration from heavy equipment or wind loads. Their role in maintaining joint integrity is vital for skyscrapers, bridges, and industrial facilities exposed to the region’s extreme weather.
Best Practices for Storage in UAE Climate
To maximize shelf life, store benjo washers in a cool, dry, and well-ventilated area away from direct sunlight and moisture. Use sealed containers or desiccant packs to control humidity, and avoid contact with corrosive substances. Regular inspections for rust or damage are advised, and inventory should follow a first-in-first-out (FIFO) system to rotate stock.
