Specification

Bolts, machine parts, fasteners with cylindrical heads, and threaded fix with nuts. Bolt: A type of fastener consisting of a head and a shaft (a cylinder with external threads), which needs to be matched with a nut to fasten two parts through holes. This connection form is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

Hex Flange Bolts are integral bolts consisting of hexagonal head and flange (the gasket under the hexagon and the hexagon are fixed together) and screw (cylindrical body with external thread), which need to be matched with nuts for fastening a part that connects two through holes.

1. Hexagon head type: One is flat and the other is concave.
2. Finish: According to different needs, the surface has white plating, green, colorful yellow, and corrosion-resistant Dacromet.Black oxide.etc
3. Flange type: According to the different use positions of the flange bolts, the size requirements of the discs are different. There are also flat bottom and serrated, and the serrated ones play an anti-skid role.
4. According to the force bearing mode of the connection:

There are ordinary and reamer bolts, flange reamer bolts should match the size of the hole and be used when the lateral force is applied.

In addition, in order to meet the needs of locking after installation, there are holes in the rods. These holes can prevent the bolts from loosening when they are vibrated. Some flange bolts without threads should be thinner, called thin rod flange bolts. This flange bolt is conducive to the connection of variable force. There are applicable high-strength bolts on the steel structure, and the head will be larger and the size will also change.

Industry use:High-strength Custom Metric Hex Flange Bolts are widely used in automobiles, connectors, electronics, mobile phones, watches and other industries.

Features of Fine thread flange bolts

• Fine-thread flange bolts are divided into full-thread, half-thread, fine-thread and very fine-thread. The head shape is an outer hexagon, and the thread is fine-thread. The distance between adjacent outer diameters is generally closer than that of coarse threads.
• The helix angle of the flange with fine teeth is smaller, which is more conducive to the self-locking of the thread, so the fine teeth are generally used where anti-loosening is required.
• The thread pitch of the fine tooth flange is small. On the same thread length, more threads are screwed in, which can reduce fluid leakage, so it is used in occasions that require sealing.
• The fine-tooth flange thread should also have the advantage of small pitch, which can play a role in fine-tuning.
