M16 316 stainless steel external tooth lock washer, resistant to salt spray for 1000 hours

Marine-Grade Corrosion Fighters

Designed specifically for marine applications, M16 316 stainless steel external tooth lock washers excel in harsh saltwater environments. With 2-3% molybdenum content, they form a protective barrier against chloride ions, passing 1000-hour salt spray tests and outperforming 304 stainless steel.

Precision Anti-Loosening Design

Compliant with DIN 6798 and GB/T 862.2 standards, these M16 washers (17mm inner diameter, 30mm outer diameter, 2mm thickness) feature 12 external teeth. When tightened, the teeth bite into surfaces, reducing loosening risk by 70% in high-vibration marine environments.

Essential for Marine Equipment

Ideal for ship deck fasteners, seawater piping systems, and offshore connectors, they withstand temperatures from -50℃ to 200℃. The 316 stainless steel construction resists crevice corrosion and maintains toughness in cold conditions, preventing brittle fractures.

Premium 316 External Tooth Solution

External teeth provide 50% greater locking force compared to flat washers. 316 steel offers 2-3 times better saltwater resistance than 304 grade, with an 8-10 year service life. While costing 30% more, it reduces lifecycle maintenance expenses by 60%.
