Set of hexagon wrenches on plastic clip

The 220/3PH-US is a set of nine Unior L-shaped hex wrenches, 1.5 to 10 mm, held on a black plastic clip. It keeps these nine metric sizes together, in size order, on a home or shop bench. Unior has been forging hand tools in Zreče, Slovenia, since 1919.

What’s on the clip

One wrench in each of nine sizes: 1.5, 2, 2.5, 3, 4, 5, 6, 8 and 10 mm. All nine are Unior article 220/3, the regular hex wrench and not the long type (220/3L), with a plain hexagon end on both the long and the short arm. The 220/3 series also includes 7, 12, 14, 17 and 19 mm, none of which are on this clip. Our single 220/3 hex keys are listed in every size here except the 10 mm.

The clip has a hanging slot, and a size number is molded beside each wrench.

Other Unior hex clip sets

We also carry Unior hex clip sets built from other wrench articles. The long-type set uses article 220/3L, and the long ball-end set uses article 220/3SL.

Care and safe use

Unior’s safety notes for the 220/3 ask you to pick the size that fits the recess exactly and never to tilt the key in the fastener. They also say never to add an extension or other lever, strike a wrench with a hammer or grind it to a new shape, and to keep it away from excessive heat, which can change the steel’s hardness.

Pro tip from our mechanics

Put each key back in its numbered slot when the job is done. An empty slot on the clip tells you which size walked off before you need it again. Our guide to Hex and Torx wrenches: how to pick → covers when an L-key is the right format and when a T-handle or Y-handle suits the job better.

FAQ

Which sizes are on the 220/3PH-US clip, and which are left out? Nine hex wrenches, one each in 1.5, 2, 2.5, 3, 4, 5, 6, 8 and 10 mm. Unior also makes the 220/3 in 7, 12, 14, 17 and 19 mm, but none of those sizes is part of this set.

Are these ball-end or long-type hex keys? Neither. They are Unior article 220/3, the regular hex wrench rather than the long type (220/3L), with a plain hexagon end on both arms. The long arm runs from 46.5 mm on the 1.5 mm key to 122 mm on the 10 mm. The long-type and ball-end clip sets are separate products built from other wrench articles.

Can I replace a single wrench if one goes missing? Our single 220/3 hex keys are listed in 1.5, 2, 2.5, 3, 4, 5, 6 and 8 mm, the same article as the wrenches on this clip. We do not list a single 220/3 in 10 mm.

What steel and finish are the wrenches, and what standard are they made to? Premium chrome vanadium steel, entirely hardened and tempered, with a nickel-plated finish. Unior makes the 220/3 hex wrench to ISO 2936.
