Hexagonal six-millimeter bolt specifications analysis
Hexagonal hexagonal six millimeter bolts are a kind of common fasteners, which have an outer diameter of 6 millimeters, a thread diameter of 6 millimeters, a pitch of 1 millimeter, and an inner hexagonal size of 4 millimeters, and they can be used in conjunction with hexagonal wrenches. Hexagonal six millimeter bolts are widely used in machining, construction engineering, furniture manufacturing and other industries.
The material and performance of the bolt
Hexagonal six-millimeter bolts are usually made of carbon steel, alloy steel or stainless steel and other materials. Carbon steel bolts have low strength and are suitable for general mechanical fastening; alloy steel bolts have high strength and are suitable for heavy-duty or high-temperature occasions; stainless steel bolts have corrosion-resistant properties and are suitable for wet or corrosive environments.
The strength grade of bolts refers to the magnitude of their load-bearing capacity, including 4.6, 4.8, 5.8, 6.8, 8.8, 9.8, 10.9, and 12.9 grades, with larger numbers indicating higher strength. When selecting hexagonal six-millimeter bolts, the strength grade should be reasonably selected according to the usage environment and requirements.
Installation Precautions
The following points should be noted when installing hexagonal six-millimeter bolts:
1. Select appropriate torque assembly tools to avoid over or under-tightening;
2. Check the bolts carefully for corrosion, damage, or deformation before installation;
3. Bolts should be coated with a certain amount of lubricant before tightening to reduce friction and improve tightening force;
4. The principle of alternating symmetry should be adopted when tightening nuts to avoid tightening skew;
5. After tightening the nut, the tightening force and spiral state of the bolt should be checked to see if it is normal.
Conclusion
Through the introduction of this article, we can understand some basic specifications and performance characteristics of hexagonal six-millimeter bolts, but also understand the installation of the bolt precautions. We hope that this knowledge can be a reference and guidance to the reader, so as to better select and apply the bolt.
