Wrenches and hex keys for mechanics, millwrights, plumbers and maintenance techs. Choose from combination and open-end wrenches, ratcheting box wrenches, adjustable wrenches, pipe wrenches, flare nut wrenches, torque wrenches, and hex keys in L-style, ball-end, T-handle and folding sets, in inch and metric sizes.

What to check before you order

  • Inch or metric. Confirm the fastener before you buy. Close sizes look alike but can round off a head.
  • Hex keys and socket head screws. Match the key to the screw. A good fit matters most on socket head cap screws and set screws.
  • Ball-end vs straight. Ball ends reach in at an angle for speed; the straight end takes more torque for breaking loose and final tightening.
  • Torque wrenches. Pick a range that puts your target torque in the middle of the scale, not at the ends, and follow the manufacturer's calibration interval.
  • Pipe and adjustable wrenches. Size them to the biggest pipe or nut you'll turn, and keep a pair for back-up holding.

Common questions

What is the difference between a combination wrench and an open-end wrench?

A combination wrench has an open end on one side and a box end of the same size on the other. An open-end wrench has open jaws on both ends, usually in two different sizes. The box end grips all sides of the nut, so it is less likely to round off a tight fastener.

Should a click torque wrench be turned down for storage?

Many makers of click-type torque wrenches recommend turning the setting down to the bottom value on the scale for storage, but not below it, to relieve spring tension. Check the instructions that came with your wrench, since requirements vary.
