Grade C Hex All Metal Cone Locknut, Zinc/Wax Cr+3 (Inch)
Grade C Hex All-Metal Cone Locknuts Zinc/Wax Cr+3 are high-strength, self-locking fasteners engineered for secure connections in demanding industrial and structural applications. Manufactured from heat-treated carbon steel to ASTM A563 Grade C specifications, these locknuts feature an all-metal design with a conical top that provides prevailing torque without the use of nylon inserts. The Zinc Cr+3 (trivalent chrome) plating offers enhanced corrosion resistance, while the wax coating ensures smooth installation, consistent torque performance, and reduced galling during tightening.
Ideal for high-vibration and heavy-load environments, Grade C All-Metal Cone Locknuts with Zinc/Wax Cr+3 finish are commonly used in construction, heavy machinery, transportation, and steel fabrication. The combination of Cr+3 zinc plating and wax coating provides excellent rust protection, smooth assembly, and environmentally safe performance. These reusable, temperature-resistant locknuts maintain their locking ability under repeated use, making them a dependable choice for critical bolted joints requiring strength, reliability, and corrosion protection.
