Titanium Hexagon Bolts Related Knowledge

Titanium manufacturers: hexagon bolts related knowledge! The so-called hex socket bolt refers to the cylinder head with hex socket shape, which can also be referred to as hex socket bolt, hex socket cylinder head bolt, hex socket bolt. Why do we have six angles instead of four or five? Many people ask, why design a hexagon instead of four corners, five corners, or some other shape? Turn the hex socket bolt 60° to restore the pattern. If the space is small, simply turn the wrench 60 degrees to install the screws. It's a tradeoff between twist Angle and side length.

If it is square, the sides are long enough, but it needs to be twisted 90 degrees to restore the body shape, which is not suitable for small space installation; If it is octagon or decagon, the recovery Angle of the graph is small, but the length of the force edge is also small, easy to round. If the screw has an odd number of lengths, the two sides of the wrench are not parallel. In the early days, there were only fork wrenches. The length of the side of the wrench head is strange, is the horn, not suitable for force.

Titanium standard parts manufacturers introduce the hardness and performance of hex socket bolts:

Generally speaking, the commonly used hex socket bolts are 4.8, 8.8, 10.9, 12.9, etc. Under normal circumstances, different brands of hex socket bolts will be selected according to different needs, which is more conducive to the performance of bolts. Let's take a look at the hardness level of the hexagon socket bolts.

Hexagon socket bolt hardness class:

Hexagon socket bolts are classified according to the hardness, tension and yield strength of the threads. This is the grade of the hex socket bolt, what is the grade of the hex socket bolt? Different product materials need different grades of hexagon bolts to correspond.

Hexagon socket bolts are divided into ordinary bolts and high strength bolts according to strength grade. Normal hex bolts are class 4.8 and high strength hex bolts are class 8.8 or higher, including grades 10.9 and 12.9. Hexagon socket bolt type 12.9 usually refers to natural black oiled hexagon head knurled screw.
