Metric Flange Bolts
Metric Flange Bolts have a hex head, protruding flange, either a smooth or serrated bearing surface and coarse machine screw threads. Use serrated to resist loosening. Materials include Class 8.8 and 10.9 steel and stainless steel. Plain finish and zinc plated are available. Also called Frame Bolts and Flange Screws, use with Flange Nuts especially when holes are oversized.
Metric hex flange bolts have good mechanical properties and can withstand high tensile, compressive, torsional and shear strengths.
It belongs to a kind of fastener connection, and it is more convenient to assemble and disassemble than other connection methods, and it is more convenient for us to overhaul. And we can also increase the preload to prevent loosening.
The steel of the metric hex flange bolts is very good in plasticity, and its high strength allows us to use it well in some special places.
Advantage
1. Since the carbon steel flange bolt is made of carbon steel, it can withstand high pressure, and the performances of tensile, compression, torsion and shear are very good.
2. Because of the carbon steel flange bolt, it is a kind of fastener connection, so it has the characteristics of convenient assembly and disassembly, good fastening effect and convenient maintenance.
3, carbon steel flange bolts are well shaped, and it also has good strength, and will not easily deform during use.
Flange bolt installation method
1. When installing the carbon steel flange bolts, we must wait for the steel structure to form a stable frame unit, and after the connection pair and the friction surface are qualified, we can install it.
2. the installation should pay attention to the direction of the bolt, generally similar to the need to circle on the side of the nut, and the side of the washer hole chamfered to be in contact with the nut.
3. When installing, you can use a manual wrench or a heightening bushing for installation.
4. For the installation of carbon steel flange bolts, the requirement to be satisfied is to be able to penetrate the hole freely. If it is not enough, then the reamer is needed to correct the hole until it can be freely penetrated.
We also accept customization order according to your samples and drawings
