Park Tool THH-1 is a super nice Allen key set with bits that can be slid back and forth, which gives all the keys a wealth of uses.

For example, it can be used both as a regular Allen key and a T-key.

The tool is made of Chrome Vanadium and S-2 steel.

All the keys have a Speedspinner that makes it quick to screw even long bolts in.

The silver-colored end is made like a regular Allen key, while the black end is called a Strip-Gripper and is particularly suitable for bolts where the head has become larger than normal.

The tool holder can be mounted on both the wall, a peg board and the like.

The set contains:

Allen keys: 2 / 2.5 / 3/4/5/6/8 / 10mm

Wall bracket
