Grade A Nylon Insert Locknut, Zinc Cr+3 (Inch)
Grade A Nylon Insert Locknuts Zinc Cr+3 are medium-strength, self-locking fasteners designed for secure, vibration-resistant connections in a wide range of industrial and structural applications. Manufactured to ASTM A563 Grade A specifications, these locknuts feature a durable nylon insert that provides prevailing torque, preventing loosening under vibration or dynamic loads. The Zinc Cr+3 (trivalent chrome) plating offers excellent corrosion resistance, a clean silver-blue appearance, and an environmentally friendly alternative to traditional hexavalent coatings.
Engineered for reliability and ease of use, Grade A Nylon Insert Locknuts with Zinc Cr+3 finish are ideal for machinery, equipment assembly, construction, and maintenance applications. The nylon insert provides consistent locking performance while allowing for multiple reuse cycles under normal conditions. The Cr+3 zinc coating enhances corrosion protection and ensures smooth installation and removal. Offering a balance of strength, durability, and corrosion resistance, these locknuts are a trusted choice for medium-duty fastening where vibration control and longevity are key.
