Spring lock washers, commonly known in the fastener industry, are essential components designed to prevent loosening under vibration and thermal expansion. Our DIN127 spring lock washers are manufactured to meet rigorous international standards, including ASTM F436/F436M, ASME/ANSI B18.22.1 USS/SAE, and various DIN specifications such as DIN125A, DIN125B, DIN126, DIN433, DIN440, DIN7349, DIN988, and DIN9021. These washers are widely used in automotive, machinery, construction, and electrical industries due to their durability and reliability.
We produce spring lock washers in a comprehensive size range from 1/4 inch to 4 inches for imperial measurements and M5 to M100 for metric sizes. This ensures compatibility with diverse fastener systems globally. The materials used include high-grade carbon steel, alloy steel, and stainless steel, each selected for specific environmental and mechanical requirements. Carbon steel variants offer cost-effective strength, while stainless steel options provide excellent corrosion resistance for harsh conditions.
To enhance performance and longevity, our washers come with various finishes such as plain, zinc plated (available in clear, blue, yellow, and black), black oxide, nickel plating, hot dip galvanized, mechanical galvanized, Geomet coating, and zinc-nickel alloy. These finishes protect against rust, wear, and chemical exposure, making them suitable for indoor and outdoor applications. For packaging, we offer flexible options including bulk in 18kg or 25kg carton boxes, palletized for safe shipping, and customized packaging based on client specifications to streamline logistics and branding.
As a trusted factory and wholesaler, we support one-stop purchasing for fasteners like bolts, nuts, screws, and pins, along with OEM parts and customized stamping services. Our commitment to quality includes pre-production sample inspections and final checks before shipment, backed by material test reports (MTR) for traceability. We provide free samples upon price agreement, with a quick sampling time of 3-5 workdays, and assist with special project solutions to meet unique customer needs.
