Frequently Asked Questions

Q: What is the difference between a standard hex bolt and a heavy hex structural bolt?

Heavy hex bolts have a larger head size compared to standard hex bolts, providing a larger bearing surface and allowing for higher tightening torque, which is critical for structural stability in heavy-duty industrial applications.

Q: Why is Hot Dip Galvanizing (HDG) preferred for these bolts?

HDG provides a thicker, more durable protective layer of zinc compared to electroplating, making these bolts exceptionally resistant to rust and corrosion in outdoor or chemically aggressive environments.

Q: Can these bolts be used for woodworking and t-track jigs?

Yes, their precision machining and strength make them excellent for high-end woodworking projects, especially when creating heavy-duty jigs or anchoring fixtures that require absolute stability.

Q: What diameter sizes are available in this structural series?

This specific series covers a range from M12 to M36, catering to a wide variety of industrial requirements from medium to heavy-duty structural loads.

Q: Are these bolts fully threaded or partially threaded?

These bolts feature a fully threaded fastener style, which is essential when the shaft needs to be inserted completely into a threaded hole for a secure finish.

Q: How do I ensure the correct grade for my structural project?

We recommend contacting our technical team with your load requirements and environment details; we can then help you select the appropriate carbon steel grade and coating to ensure safety and compliance.
