What’s the difference between 6-point and 12-point sockets? Which should I use?
6-point sockets grip the flat sides of a bolt or nut, not the corners. That means less chance of rounding off stubborn, rusted, or high-torque fasteners. If you’re breaking loose suspension bolts or engine hardware, 6-point is the safe bet for max grip and strength.
12-point sockets fit both hex and double-hex fasteners. They’re easier to position in tight spots since they engage every 30° instead of every 60°.
For most jobs, 6-point is stronger and more slip-resistant, but 12-point can save time in cramped spaces or for lighter-duty, clean fasteners.
What’s the difference between 1/4", 3/8", and 1/2" drive tools?
1/4" drive: Small, lightweight, and perfect for tight spaces and small fasteners: think interior panels, electronics, or lawn equipment.
3/8" drive: The all-purpose workhorse. Handles most automotive and household fasteners. If you’re starting out, this is the size you’ll use most.
1/2" drive: Built for big jobs: suspension, lug nuts, axle bolts, or anything that needs real torque. Heavier, but handles the tough stuff.
It's common to build sets around 3/8" and add 1/4" for precision or 1/2" for muscle as needed.
When do I need deep sockets instead of standard sockets?
Standard (shallow) sockets are great for most nuts and bolts. Deep sockets are made for jobs where the bolt or stud sticks out past the nut, like shock mounts, exhaust hangers, or spark plugs. Deep sockets can reach over long threads where a standard socket bottoms out.
What’s the difference between chrome and impact sockets? Can I use them interchangeably?
Chrome sockets are made for hand tools. They’re strong, shiny, and resist corrosion, but they’re brittle compared to impact sockets. Use them with ratchets or breaker bars, never with an impact gun.
Impact sockets are made from tougher steel and have a black oxide finish. They’re built to handle the pounding from impact wrenches without shattering. They’re thicker walled, so they absorb shock and reduce the risk of splitting.
Never use a chrome socket on an impact gun. It can crack or shatter, sending metal flying. You can use impact sockets with hand tools, they’re just bulkier, but not the other way around.
Should I get metric or SAE? Do I really need both?
If you’re working on anything made in the last 30 years, especially cars, motorcycles, and power tools, you’ll need metric. SAE is still common on older American vehicles, lawn equipment, and some plumbing.
“Close enough” isn’t good enough. Using the wrong size can round off fasteners. If you work on a mix of vehicles and equipment, having both saves time and headaches.
How do I keep my tool set organized and avoid losing sockets. Especially the 10mm?
Always return sockets to their tray or rail after use
Use labeled organizers or magnetic trays, especially for smaller sizes
Clean and dry tools before putting them away to prevent rust
If you’re working on a project, keep a small parts tray nearby for fasteners and sockets
For the 10mm sockets, honestly just consider it a donation to the socket gods.
