What does HDG mean for hex bolts?
HDG stands for hot-dip galvanised, a process that coats the bolt with a layer of zinc to protect against corrosion. This makes HDG bolts ideal for outdoor and harsh environments.
How to install hex head bolts correctly?
Hex bolts are installed by inserting them through aligned holes and tightening with a nut using appropriate tools. Proper torque ensures secure fastening and long-term performance.
Are hex head bolts compatible with threaded fastener systems?
Yes, hex head bolts are commonly used with threaded rods, nuts and other fastening components, making them an integral part of complete fastening systems.
What materials and finishes are available for hex bolts?
- Hot-dip galvanised steel for outdoor use
- Zinc plated steel for indoor applications
- Stainless steel for corrosion-sensitive environments
These options ensure durability across different applications.
How to choose the right hex head bolt and nut?
Selection depends on load requirements, environmental conditions and compatibility with other components. For outdoor use, galvanised or stainless steel options are recommended, while zinc-plated bolts are suitable for indoor installations.
What are the advantages of using hex head bolts in structural applications?
