Frequently Asked Questions (FAQs)
1. What is a hex bolt used for?
Hex bolts are commonly used to secure objects together or against other objects, providing a secure and non-loosening hold. They are used in various applications, such as fastening steel to steel, wood to wood, and other materials found in construction projects like buildings, bridges, and highway structures.
2. What are the disadvantages of hex bolts?
One disadvantage of hex bolts is their higher profile compared to other fasteners. The tools used to tighten them, such as wrenches or sockets, can also take up more space. This can be challenging when working in tight spaces or when carrying limited equipment.
3. Are hex bolts strong?
Yes, hex bolts can be strong, particularly grade 9 structural bolts. Grade 9 hex bolts have a tensile strength of 180,000 PSI, making them one of the strongest structural bolts available. They are commonly used in applications that require high strength and reliability.
4. What are the advantages of a hex bolt?
Hex bolts offer several advantages over other fasteners. Their hexagonal shape allows for easy tightening or loosening without the need for additional tools. This makes them convenient for quick adjustments or repairs on-site, eliminating the need to carry bulky equipment.
5. Why are 12 point bolts used instead of hex bolts?
12-point bolts are used in place of hex bolts because they can be tightened with a 12-point socket wrench, allowing for higher torque application. This makes them suitable for applications that require greater tightening force. Additionally, the 12-point head design is advantageous in tight spaces.
6. Which is stronger hex or torx?
Torx bits have a higher surface area for torque application and a 15º drive angle, compared to the hex's 60º angle. This results in increased tolerance, effectiveness, and less tool slippage. Therefore, Torx fasteners can provide a stronger and more secure connection than hex fasteners.
7. Why is Torx better than hex?
Torx fasteners have a higher surface area for torque application and a 15º drive angle, in contrast to the hex's 60º angle. This design allows for increased torque tolerance, improved effectiveness, and reduced tool slippage. Consequently, Torx fasteners are often considered superior to hex fasteners in terms of performance and reliability.
