What's the difference between standard and deep sockets, and when would I use each?

Standard sockets are best for accessing fasteners with plenty of clearance around them. Deep sockets, like some Grey Pneumatic impact sockets, provide extra length to reach recessed fasteners or those on long bolts. Consider a deep socket if you frequently work on engines or suspensions where access is limited. Keep in mind that deep sockets may not fit in tight spaces where a standard socket would work.

What does '6 point' vs. '12 point' refer to in socket design, and which is better?

The terms '6 point' and '12 point' refer to the internal shape of the socket that grips the fastener. A 6-point socket grips the fastener on its six corners, offering a more secure grip and reducing the risk of rounding off the fastener, especially when dealing with stubborn or corroded bolts. A 12-point socket engages the fastener at twice as many points making it faster to engage the fastener. For most high-torque applications, a 6-point socket, like the Grey Pneumatic 3/8 Inch Drive Magnetic 6 Pt Deep Length Impact Socket, is generally preferred.

What does 'SAE' mean, and why is it important when choosing a socket set?

'SAE' stands for Society of Automotive Engineers, and in the context of sockets, it refers to sockets measured in inches. It's crucial to choose the correct measurement system, as SAE and metric sockets are not interchangeable. Using the wrong size can damage the fastener or the socket. If you're working on American-made vehicles or equipment, you'll likely need SAE sockets.

What's the difference between impact and non-impact sockets?

Impact sockets are specifically designed for use with impact wrenches and drivers. They are made from a tougher alloy steel, like chrome-molybdenum (Cr-Mo), and undergo a different heat treatment process to withstand the high torque and repeated impacts. Non-impact sockets, often made from chrome vanadium (Cr-V) steel, are not designed for impact tools and can shatter or crack under high stress. Always use impact-rated sockets with impact tools for safety and tool longevity.

What are 'driver sockets' and what are they used for?

Driver sockets aren't for standard nuts and bolts; instead, they are designed to fit specific types of fasteners like Torx, hex, or spline bolts. For example, Sunex Tools makes a variety of Torx driver sockets. Using the correct driver socket ensures a secure grip and prevents damage to the fastener head. Common applications include automotive repair, machinery maintenance, and electronics assembly.

What are tap sockets used for?

Tap sockets are designed to hold and drive taps, which are tools used to create internal threads in holes. They provide a more secure and efficient way to turn a tap compared to using a wrench directly on the tap's square end. Tap sockets, like those from Lisle, are especially useful in tight spaces where a T-handle tap wrench won't fit. Be sure to select the correct tap socket size for the tap you are using.

What should I consider when choosing a socket set if I work on classic cars?

When working on classic cars, consider the age and origin of the vehicle. Many older American cars use SAE fasteners, so a comprehensive SAE socket set is essential. Also, consider the condition of the fasteners. Older vehicles often have corroded or damaged bolts, so investing in high-quality sockets that provide a secure grip, like 6-point sockets, is crucial to prevent rounding off the fastener heads. Penetrating oil and patience are also your friends.
