Frequently Asked Questions (FAQs)
1. Is a double hex socket safe to use on an impact gun?
No, it is not safe to use a regular hand tool socket on an impact gun. Regular sockets are not designed to withstand the high torque and impact forces generated by power tools. They may shatter due to their thinner wall design and material. It is important to use impact sockets specifically designed for use with impact guns to ensure safety.
2. What is the use of impact hex socket?
Impact hex sockets, also known as hex bit sockets or allen sockets, are used for tightening socket cap screws and bolts with pneumatic or hydraulic impact wrenches. They provide precision and accuracy in securing locking pins and O-rings onto the impact wrench, making them an essential tool for various applications.
3. What are the two types of hex keys?
There are several types of hex keys available, including L-Style Allen wrenches, T-handle hex keys, P-handle hex keys, folding hex keys, ratcheting drivers, torque wrenches, Allen screwdrivers, and ball hex sets.
4. What size hex bits can you use on an impact driver?
Impact drivers can only be used with 1/4" hex shank accessories. However, it is important to note that not all hex shank drill bits are suitable for use with impact drivers. Some drill bits with hex shanks may not be designed for the high torque and impact forces of an impact driver, and using them may cause them to shatter.
5. When not to use impact sockets?
If you are using a manual ratchet for personal work that does not involve impact work, a regular socket will suffice. Impact sockets are specifically designed to withstand the high torque and impact forces generated by impact tools. If you are not using an impact tool, there is no need to invest in professional impact sockets.
6. Do you really need impact sockets?
Yes, impact sockets are essential when using heavy contact air tools like impact wrenches. Regular sockets may disintegrate under the high impact forces of these tools, posing a safety risk. Impact sockets are designed to withstand the impact and torque generated by impact tools, ensuring safety and preventing injuries.
7. What are the disadvantages of hex screws?
Hex screws have some disadvantages compared to other types of fasteners. They have a higher profile, which means they may not be suitable for tight spaces. The tools used to tighten hex screws, such as wrenches or sockets, can also take up more room. Additionally, accessing and tightening hex screws can be challenging in confined areas.
