Common questions
What is the difference between a combination wrench and a regular wrench?
A combination wrench has an open end on one side and a box end on the other, offering versatility. Regular wrenches have only one type of end, such as open or box. Combination wrenches are more common in sets.
Are expensive wrench sets worth the money?
For frequent heavy use, premium sets offer better steel, finishes, and warranties, which can save money in the long run. For occasional DIY, a mid-range set may suffice, but you risk rounding bolts if the fit is poor.
What size wrench set should I buy?
A set with sizes from 8mm to 19mm (or 5/16 to 3/4 inch) covers most automotive tasks. If you work on larger industrial equipment, consider sets up to 24mm or 1 inch.
Can I use wrenches on impact tools?
No, standard wrenches are not designed for impact use. They can shatter. Use impact-rated sockets and wrenches for power tools.
How do I prevent rounding bolts?
Use the correct size wrench, ensure it fully engages the fastener, and apply steady pressure. Anti-slip designs help. Avoid using worn or oversized wrenches.
What is the best material for heavy-duty wrenches?
Chrome vanadium steel is the most common for its strength and corrosion resistance. Alloy steel is even stronger but heavier. Some premium wrenches use titanium, but they are costly.
Should I choose metric or SAE wrenches?
It depends on what you work on. Most modern vehicles use metric fasteners, while older cars and some industrial equipment use SAE. Having both sets is ideal, but if you must choose, pick based on your primary use.
How should I care for my wrench set?
Clean them after use with a dry cloth, and store them in a dry place. Apply a light oil if they get wet. Avoid dropping them, as this can damage the edges.
Do wrench sets come with a warranty?
Many reputable brands offer a lifetime warranty, such as Craftsman, TEKTON, and GearWrench. Check the product details for warranty information.
Can I use a wrench on a damaged fastener?
A six-point wrench may grip better on rounded fasteners. Some anti-slip wrenches are designed for this. If the fastener is severely damaged, you may need a bolt extractor.
The bottom line
For most people, the TEKTON 20-Piece Combination Wrench Set offers the best balance of strength, grip, and value. It is an investment that will serve you for years. If you are on a tight budget, the CRAFTSMAN 12-Piece is a reliable alternative, but consider upgrading if you frequently tackle tough jobs.
