Zinc Plated Serrated Hex Flange Lock Nuts

Zinc Plated Serrated Hex Flange Lock Nuts adopt one-piece forging molding without secondary assembly. The integrated serrated flange forms countless friction points when fastened, effectively resisting loose caused by long-term vibration. Raw material selects medium carbon steel, with strength grades covering Class 4, Class 8 and Class 10 to match different load-bearing standards. The electroplating process forms uniform zinc coating with thickness 5μm–12μm, which can block oxygen and moisture to slow metal oxidation. This structural design cuts auxiliary anti-loose washer usage by 1 set for each connection point and simplifies on-site installation procedures.

Production Quality Control Supported by Ningbo Gangtong Zheli Fasteners Co., Ltd.

Ningbo Gangtong Zheli Fasteners Co., Ltd. builds full production lines including forging, tapping and surface treatment for all fastener series. All raw steel coils pass tensile strength and hardness inspection before cutting, and semi-finished nuts carry batch tracking marks for full traceability. Every batch of finished fasteners goes through salt spray testing, torque testing and thread gauge inspection to meet international hardware acceptance standards. For Zinc Plated Serrated Hex Flange Lock Nuts, the factory sets special inspection stations to check serration completeness and zinc layer uniformity, rejecting products with incomplete teeth or uneven plating directly to stabilize overall pass rate above 99.2%.

Wide Application Scenarios of Industrial Grade Fasteners

Mechanical equipment, light automobiles, metal frame construction and agricultural machinery are the main matching fields for this fastener series. Frame assembly factories favor this product because the flange surface evenly disperses pressure to avoid base plate deformation during locking. Many overseas hardware distributors cooperate with Ningbo Gangtong Zheli Fasteners Co., Ltd. to purchase mixed specifications for downstream machinery repair clients. Compared with ordinary hex nuts, Zinc Plated Serrated Hex Flange Lock Nuts omit flat washers in most mounting environments, reducing spare part inventory pressure for buyers and lowering overall assembly material cost.

Complete Specifications & Surface Treatment Options

This fastener series covers common metric thread sizes from M6 to M16, supporting three mainstream surface finishes: color zinc plating, blue-white zinc plating and black zinc plating. All size molds are self-developed and maintained by the factory’s technical team to guarantee consistent thread tolerance within 6H standard range. Clients can select single-size bulk packaging or mixed-spec carton packaging according to project demand. Stable raw material supply chain ensures continuous production capacity, and the complete specification matrix enables one-stop fastener procurement for most industrial installation projects without matching extra auxiliary locking parts besides Zinc Plated Serrated Hex Flange Lock Nuts.
