Hexagon Flange Head Bolts

Stainless Steel Phillips Indented 5-Point Hexagon Head Hex Flange Bolt

Introduction

Hex Flange Bolts are regular hex head bolts that feature a built-in washer and an externally threaded body. These bolts come in plain or serrated flange configurations and are also known by various names, including hexagon flange bolts, frame bolts, and simply flange bolts. The dimensions of hex flange bolts are standardized in both metric and imperial sizes, adhering to unified national coarse pitch (UNC), fine pitch (UNF), fine pitch (UN), and ISO metric thread profiles. These bolts are manufactured across all material categories and ASTM specifications. Hexagon flange bolts are prevalent in the automotive industry, particularly in the frames of trucks and heavy vehicles, and they are also closely related to carriage bolts in terms of their function and application.

Application

Mechanics
To establish a reliable and long-lasting connection between two sections of a large and enclosed area, a flange bolt is essential. A prime example is the connection between the transmission and the engine in a vehicle. Both the engine and transmission contain numerous moving parts that can easily be damaged by small objects, debris, or dust. In this scenario, the flange bolt plays a crucial role in securing the outer casing that protects the engine and transmission.

Another common application of flange bolts in the automotive industry is in the car's exhaust system. Replacing traditional bolts and washers with flange bolts and springs for a vehicle's exhaust ensures enhanced strength and reliability.

Plumbing
Plumbers have numerous options when connecting two pipes together. While welding or soldering the ducts together is efficient, cylinders fastened via these methods are more prone to bursting when exposed to high pressure. A safer method of connecting pipelines involves securing their ends with flange bolts. This ensures that the pipes will hold, regardless of the type of gas or liquid inside the ducts.

Electronics
While the fasteners found in electronic devices are not designed to sustain high pressure, they still need to securely hold the small components inside to prevent particles from entering the device and damaging sensitive parts. These types of flange bolts are significantly smaller than those used for connecting pipelines or fasteners in the automotive industry. For example, the small fastener that connects the body of a camera to the glass of the lens is a flange bolt.

Features

The Hex Flange Bolts exhibit the unique characteristics of hexagon bolts with a flange that distributes the forces under the bolt head over a larger area, resulting in lower surface pressure.
