Hex Flange Bolt

Product Introduction

Hexagonal flange bolts are high-performance fasteners that integrate a hexagonal head with a flange, widely used in critical areas such as power fittings and fiber optic cable accessories. Compared to traditional bolts with washers, this design provides a larger load-bearing area and more uniform clamping force, effectively preventing loosening.Handan Jinmai Fastener Manufacturing Co., Ltd. specializes in the research and development and production of these fasteners, manufacturing them strictly according to relevant domestic and international standards. Customization is available to meet the specific needs of different engineering projects.

Product Features

Integrated Structure: The flange and bolt head are integrated, eliminating the need for additional washers during installation and simplifying assembly.

Excellent Anti-Loosening Performance: The flange increases the contact area, distributing preload; some models feature anti-slip serrations for vibration resistance and anti-loosening.

Wide Applicability: Suitable for various applications including power transmission towers, communication base stations, and power transmission and transformation equipment.

Manufacturing Process

We manufacture the bolt bodies using a multi-station cold heading process, resulting in high material utilization and excellent mechanical properties. Precision heat treatment (quenching and tempering) is performed according to strength requirements. Various surface treatments are available, including galvanizing and Dacromet coating, to meet the corrosion protection needs of different environments.

Technical Specifications

Thread specifications: M5-M24 (metric), #8-1 (imperial)

Strength grade: 4.8 to 12.9 (carbon steel), A2-70/A4-80 (stainless steel)
