What's the difference between SAE and Metric tool sets, and which one should I choose?

SAE (Society of Automotive Engineers) uses inch-based measurements, while Metric uses millimeters. Choosing the right set depends on the fasteners you'll be working with. Many mechanics find it useful to have both SAE and Metric sets, especially when working on a variety of vehicles or equipment.

I need a comprehensive tool set. What should I look for in a 'loaded tool box' or a large, multi-piece set?

When considering a loaded tool box or a large set like a 1000-piece set, pay attention to the quality of the individual tools, not just the quantity. Look for durable materials like chrome vanadium steel, and consider the range of tools included. Brands like NEPROS and GearWrench are known for quality and comprehensive sets.

What are the advantages of different drive sizes (1/4", 3/8", and 1/2") in socket sets?

Smaller drive sizes like 1/4" are ideal for delicate work and tight spaces, while 3/8" offers a good balance of torque and accessibility. Larger 1/2" drives are designed for high-torque applications, such as loosening stubborn bolts. Many sets include all three drive sizes for maximum versatility.

What's the difference between 6-point and 12-point sockets, and when should I use each?

6-point sockets grip the fastener more securely, reducing the risk of rounding off bolts, especially when dealing with high torque. 12-point sockets offer more engagement points, making them easier to use in tight spaces or at awkward angles. Consider a set with both types for different applications.

What should I consider when buying a hex key set, especially a folding one?
