Tuff Stuff 8 Piece Fold-Up Hex Key Set

This compact set contains eight hex keys ranging from .050 inch to 5/32 inch. Each size is clearly marked on the ergonomic handle for quick identification. The fold-up design keeps the keys organised and ready for use. It is built for mechanics and hobbyists needing a portable selection of small fasteners.

Suited for tight small-fastener work

The range covers common small hex sizes found on precision equipment and bicycles. A flat spring in the case bottom holds each key at any angle during use. Buyers needing larger hex sizes or Torx profiles will not find them in this set. It is not intended for high-torque applications requiring long leverage.

8650 Chrome Nickel Alloy Steel Construction

Keys are drawn to a tolerance of plus .000 minus .001 for precise fit. Sharp, clean hex corners reduce the risk of rounding fastener heads. This material choice supports durability across repeated use. The steel specification is the primary indicator of the set's service life.

Questions about this item

Will the .050" key in this set fit the tiny set screws on my vintage guitar bridge?

The set includes a .050" key along with 1/16", 5/64", 3/32", 7/64", 1/8", 9/64" and 5/32" keys, all made from 8650 chrome nickel alloy steel drawn to a tolerance of plus .000/minus .001 for precise fit in small fasteners.

How can I verify the keys are hardened correctly after I start using them?

The 8650 chrome nickel alloy steel is drawn to a tolerance of plus .000/minus .001 with sharp, clean hex corners that resist rounding; if the keys engage fasteners cleanly without stripping or deforming under normal torque, the heat treatment is performing as intended.

Does the fold-up handle include the flat spring to hold keys at angle, or do I need to buy that separately?

The fold-up handle comes with a flat spring in the case bottom that holds keys at any angle during use; all eight keys are permanently housed in the handle so nothing extra is required.
