Serrated Flange Hex Locknut, Case Hardened, Zinc Cr+3 (Inch)
Serrated Flange Hex Locknuts, Case Hardened, Zinc Cr+3 are high-performance fasteners designed to provide secure, vibration-resistant locking in mechanical, automotive, and industrial applications. These nuts feature an integrated flange that distributes the load over a wider surface area and serrations on the bearing face that bite into the mating material to prevent loosening under vibration. Case hardening enhances surface strength and wear resistance, while maintaining a tough, ductile core for reliable performance. The Zinc Cr+3 (trivalent chrome) plating offers excellent corrosion resistance and a clean silver-blue appearance.
Engineered for strength and durability, these Case Hardened Serrated Flange Hex Locknuts with Zinc Cr+3 finish are ideal for use in machinery, equipment assembly, and automotive fastening where resistance to vibration and corrosion is critical. The environmentally friendly Cr+3 coating provides long-lasting protection against rust while ensuring smooth installation and consistent torque performance. Combining secure locking action, superior surface hardness, and reliable corrosion protection, these nuts deliver dependable fastening in demanding applications.
