Hexagonal flange face bolts mechanical action industry solutions

I. Definition and structural characteristics

A hexagonal flange face bolt combines a hexagonal nut and a flange face bolt commonly used in connecting the industrial production of various equipment and mechanical parts. The nut and hexagonal flange face characterize its structure. The nut is hexagonal, with an internal thread structure. Flange face bolts have hexagonal protrusions and a larger diameter.

Hexagonal flange face bolts are a kind of fasteners composed of hexagonal heads and flange as well as screws. This kind of bolt has a wide range of applications in steel structure connection, and its performance grade can be divided into several grades according to different needs, such as 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9 and so on more than ten grades. The grade 8.8 and above bolts are made of low-carbon alloy or medium-carbon steel and are heat-treated (quenched and tempered), usually called high-strength bolts.

II. Mechanical action

1. Tightening force: The primary function of hexagonal flange face bolts is to fix the connecting parts by providing tightening force. The connecting parts can be clamped together by rotating the flange face bolts, preventing them from moving and bending during mechanical work. Hexagonal flange face bolts are characterized by the design of their flange, which can deform slightly, allowing them to lock together more firmly. This design enables the Hex Flange Face Bolt to provide better stability when connecting two objects. In addition, because of its smaller head, the flange underneath also plays a fastening role and can be used with a unique tool to go up into the hole, and the principle of the hexagonal bolt is similar.

2. Improved mechanical safety and stability: In many applications, hexagonal flange face bolts are more reliable and durable than other bolts. Their mechanical safety and stability are higher than ordinary bolts, which can ensure that the connecting parts will not be loosened or destroyed during mechanical operation.

3. Wide range of applications: Hexagonal flange face bolts are not constrained and can be connected to various mechanical parts, including members, sprockets, rollers, rods, disks, etc.

III Classification of hexagonal flange face bolts

1. Hexagonal head type, which is the flat brain, and the other is the concave brain.

2. The surface color category: according to different needs, the surface has white plating, military green, color yellow, and corrosion-resistant Dacromet.

3. Flange category: The size of the disk requirements are different according to the flange bolts used in different locations. The disk has a flat bottom with the teeth of the points and the teeth of the anti-slip role.

4. According to the connection of the force mode, there are ordinary and reamed holes. The flange bolts for reamed holes should match the hole size and be used when subjected to transverse force.

In addition, to meet the locking needs after installation, holes in the rod can prevent the bolt vibration from coming loose.

Some flange bolts do not have threaded rod parts, called thin rod flange bolts. This kind of flange bolt is favorable for connecting variable force.

High-Strength Grade 8 Steel Flanged Hex Head Screws: Made from Grade 8 steel, these screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. The material meets SAE J429 specifications for quality. Dimensions meet IFI 111 specifications. Grade 8 steel hex head screws are marked with six radial lines. Head height includes the flange. Length is measured from under the flange.

Black-phosphate steel screws are mildly corrosion-resistant in dry environments. Zinc yellow-chromate plated steel screws resist corrosion in wet environments.

Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Fine threads are closely spaced to prevent loosening from vibration.

High-Strength Metric Class 10.9 Steel Flanged Hex Head Screws: Choose these Class 10.9 steel screws for high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. Head height includes the flange. Length is measured from under the flange.

Black-phosphate steel screws are mildly corrosion-resistant in dry environments. Zinc yellow-chromate plated steel screws resist corrosion in wet environments.

Screws that meet ISO 898-1 or SAE J1199 comply with specifications and testing requirements for material quality. Screws that meet ASME B18.2.3.9M or DIN 6921 comply with specifications for dimensional standards.
