Eye Nut is the core connection component in the installation of power fittings and optical fiber lines, and is designed for high-altitude lifting, equipment fixing and line tension adjustment. Handan Jinmai Fastener Manufacturing Co., Ltd. (established in 2010) is a professional fastener manufacturer in North China. Relying on the resources of the standard parts industrial belt in Yongnian District, it uses precision forging technology to produce a full range of high-strength Eye Nuts. The product supports customization of materials, apertures and load levels according to customer drawings to meet the needs of multiple scenarios such as power, communications, and railways.
1. High-strength safety structure
Forged with Q235B/45# steel, tensile strength ≥500MPa, passed GB/T 2317.1 national standard test, can bear 5-50 tons of dynamic load.
2. Corrosion resistance
Surface hot-dip galvanizing treatment (zinc layer ≥86μm), salt spray test over 2000 hours, adaptable to high humidity, strong acid and alkali environment.
3. Quick installation design
Integrated thread and annular hanging hole, compatible with M12-M64 standard bolts, supports 360° rotation adjustment, and reduces installation torque loss.
1. Precision die forging
Use a 630-ton friction press to forge the blank to eliminate internal pores and increase metal density.
2. Heat treatment strengthening
Quenching + tempering process (850℃ oil quenching + 450℃ tempering), the hardness reaches HRC22-30, balancing toughness and strength.
3. Fully automatic surface treatment
A four-step process of pickling → plating → hot-dip galvanizing → passivation, combined with shot blasting and rust removal, ensures that the coating is uniform and does not fall off.
