Colour Coded Torx & Hex Head Allen Key Set

Grab the right size first go, not the third.

Every key set ends up the same way. Nine identical bits of black steel in a roll, the size stamps polished off years ago, and you are guessing. You try one and it feels loose. You try the next and it feels loose too. Then you lean on it anyway, because the light is going and you want to be finished.

That is where it turns into a real job. A key a hair undersize rounds the socket out. A rounded socket means an extractor, a drill, or a run into town for a fastener you already had in your hand. A two-second identification problem becomes an afternoon.

These sets colour the arms. Every size gets its own colour, and the size is etched into the steel beside a Cr-V mark, so you pick by sight and check by reading rather than by trial and error. Nine keys to a set, sitting in a moulded holder that keeps them in order instead of loose in the bottom of the toolbox.

Pick the set that matches the fasteners you actually deal with: hex or Torx, short arm or long arm, or the folding multi-head that clips onto a belt loop and lives in the crib bag.

What It Does

• Sorts by sight: one colour per size, so you reach for the right arm instead of working down the row.
• Confirms by reading: the size is etched into the steel on every arm, so the colour is not the only thing you are trusting.
• Reaches down a recess: the long-arm sets run to 230 mm on the 10 mm hex and 212 mm on the T50, for counterbored and sunk fasteners.
• Works off the axis: the hex sets carry a ball end on the long arm, so you can drive a bolt you cannot get square to.
• Gets into tight gaps: the short-arm sets swap reach for a stubby profile that fits where a long key will not swing.
• Folds for the pocket: the multi-head set closes into its own body and clips on with a carabiner.

Key Features

• Nine keys per set: every one of the five options is a nine-piece set, not a mixed kit.
• Chromium-vanadium steel: the arms are marked "CR-V" alongside the "FUTE" brand etch and the size.
• Hex range 1.5 to 10 mm: 1.5, 2, 2.5, 3, 4, 5, 6, 8 and 10 mm in both the short and long sets.
• Torx range T10 to T50: T10, T15, T20, T25, T27, T30, T40, T45 and T50 in both the short and long sets.
• Two arm lengths: the long 10 mm hex runs 230 mm against 178 mm on the short set — full lengths for every size are in the Specs tab.
• Ball end on hex: long arm is ball ended, short arm is plain hex for when you want the full flat bearing on the socket.
• Moulded holder: the four L-key sets come in a plastic holder with a hanging hole, so the set stays a set.
• Folding multi-head option: six hex sizes plus Phillips, slotted and a T25, on a carabiner.
• Colour on the arm, not a sticker: the coating is on the shaft, so it is not going to peel off in the first week.

Limits

Straight up about what these are and are not.

• You get one set, not five: the drop-down picks a single nine-piece set. It is not a combined hex-and-Torx kit at that price.
• Hex and Torx do not overlap: the hex sets contain no Torx sizes and the Torx sets contain no millimetre sizes. If you deal with both, that is two sets.
• No ball end on Torx: the star tips drive square to the fastener only. That is how Torx works, not a shortcoming of this set.
• Tamper-proof is unconfirmed: the supplier’s own size icons show solid star tips, which points to standard Torx rather than the drilled type that fits security screws. Nothing in the listing states it in writing and the close-up photograph is too soft to call, so treat these as standard Torx.
• The folding set is the light option: hex 2 to 6 mm only, and a folding body gives you less leverage than a long L-key. It is a carry-it-everywhere set, not a workshop set.
• Hand tools only: these are not made for an impact driver or a drill, and no impact rating is published.
• No hardness or torque figure: the supplier states the steel type but publishes no HRC number and no torque limit. We are not going to invent one.
• No certification sighted: no standard is printed on the tools or the packaging in any photograph, and we have not sighted a test certificate.
• No full colour chart: the supplier does not publish which colour is which size. The largest key in each set is blue; the rest you read off the etch.

Q & A

Which set should I pick?

Look at the fasteners you actually undo. Six-sided socket, pick hex. Six-pointed star, pick Torx. Then choose long arm for reach and leverage down a recess, or short arm for tight spots. If you want something for the crib bag or the bike rather than the shed, take the folding multi-head.

Are the hex sizes metric?

Yes. 1.5, 2, 2.5, 3, 4, 5, 6, 8 and 10 mm. There are no imperial sizes in any of these sets. Torx sizes are T-numbers, which are a fastener designation rather than a measurement, so they do not convert.

Will the Torx set undo security screws with a pin in the middle?

Assume not. A key that fits a pin-in-Torx screw has a hole drilled up the centre of the star, and the supplier does not state that these do. The size icons on the supplier’s own chart show solid tips. If you specifically need tamper-proof keys, this is not the set to bank on.

What is the real difference between the short and long sets?

The long arm. On the 10 mm hex it is 230 mm against 178 mm, and on the T50 it is 212 mm against 159 mm. The short arms are within a millimetre or two of each other across both sets. Longer means more reach and more leverage; shorter means it fits where the long one fouls.

Can I run these in a drill or an impact driver?

No. They are L-keys for hand use. There is no hex drive shank, no impact rating published, and putting a rattle gun on an unrated key is how you snap a tip off inside a fastener.

How long does delivery take?

Allow 10 to 14 days from the day you order, and up to three weeks if you are regional or remote. Delivery is free to Australia and New Zealand.
