Hex Socket Flange Bolt
Automotive parts Motorcycles Machinery and equipment Mold equipment Industrial assembly

Product Introduction
A hex socket flange bolt is a high-performance fastener that combines a hex socket drive with a flange design. The bolt head features a hex socket hole that can be installed with a hex wrench, while the bottom flange increases the bearing area, improving connection stability.
WT Fasteners specializes in producing various specifications of hex socket flange bolts. We can provide different materials, strength grades, lengths, and surface treatment options according to customer requirements, supporting customization of standard and non-standard parts.
Hex socket flange bolts are widely used in machinery and equipment, automotive parts, automation equipment, mold manufacturing, electronic equipment, and industrial assembly.
Product Features
1. Hex Socket Drive Design
The hex socket hole structure ensures even force distribution during installation, suitable for confined spaces, improving assembly convenience.
2. Integrated Flange Structure
The bottom flange increases the contact area, can replace washers, disperses fastening pressure, and improves connection reliability.
3. High Strength Performance
Made of high-quality alloy steel, it can achieve high strength grades, suitable for high-load and high-precision connection environments.
4. Good Anti-Loosening Effect
The flange design increases friction, reducing the risk of loosening in vibration environments.
5. Non-Standard Customization
Custom head sizes, thread specifications, lengths, and surface treatments can be made according to customer drawings or samples.
