XunLiu M4 316 Stainless Steel Split Lock Washers (Pack of 50)

XunLiu 316 Stainless Steel Split Lock Washers — Built for the Toughest Conditions When standard washers fail in wet, salty, or chemically aggressive environments, XunLiu 316 SS washers hold firm. Why 316 over 304? The addition of 2–3% molybdenum in 316 stainless steel dramatically improves resistance to chlorides, seawater, and acidic substances — making it the go-to choice for marine engineering, food processing, chemical equipment, and outdoor infrastructure. The split spring-lock design delivers consistent axial pressure after tightening, preventing bolt loosening caused by vibration or thermal expansion — critical in heavy machinery and dynamic load environments. Manufactured to tight ±2% tolerances for a perfect fit with standard metric bolts. The 50-piece pack offers excellent value for factory stock, professional engineers, and serious DIY builders alike.

• Premium 316 Stainless Steel Grade — Contains molybdenum for superior resistance to chloride, acid, and alkaline corrosion compared to standard 304 SS, ideal for marine and harsh environments.
• Exceptional Rust & Oxidation Resistance — Precision-finished surface stays rust-free even with prolonged exposure to moisture, saltwater, and chemicals — reducing maintenance and replacement costs.
• Reliable Spring-Lock Mechanism — Split lock design applies constant spring tension to prevent bolt loosening under vibration, ensuring secure fastening in heavy machinery and industrial equipment.
• Versatile Applications — Perfect for ships, offshore equipment, outdoor construction, chemical pipelines, automotive components, and general industrial fastening projects.
• Multiple Sizes Available, Great Value — Available in M2 to M24 sizes; meets bulk needs. Slightly higher price than 304 SS is offset by significantly better durability and corrosion performance.
