Silca’s Travel HX-Two Travel Kit May 22, 2018

The thing I use the most in my toolkit is my Silca HX-One home wrench set, yet I never bring it on the road with me because I’m afraid of losing some of the tiny bits in the black hole that is my truck. After the success of the HX-One home kit, Silca announced their HX-Two travel kit. These are not your standard hex wrenches. Not at all. This is Silca after all.

These wrenches are heat treated with a 9 step process, with a high grip polymer coating over high-engagement satin chrome. After over two years of heavy use, my HX-One wrenches still look brand new. The hex keys in the set, which include 10, 8, 6, 5, 4, 3, 2.5, 2, and 1.5mm, and Torx® keys include T30, T27, T25, T20, T15, T10, T9, T8, and T7. See more at Silca.

  • Super into this set over the HX-One, AND a full set of nice Torx keys is something I need to add anyway.

    Most of these tool sets are just rebrands with a different label marked up 500-1000%

      I think they are trying to sell them to the same people looking to spend $120 on a firefly seat clamp.

      • Every mechanic I know that uses Silca’s tools say they have resisted any torsion / wear / tear and swear by their durability. I dunno how much time you spend in a shop, but Park’s tools twist and get ruined pretty easily. So, mechanics either re-buy park tools every year or so, or just buy one set of Silca.

          Thanks John for the kind words! Yes, these are made from fine grain Swiss S2 Tool Steel, custom 9 stage heat treated (takes more than 24 hours) with custom high-friction chrome and custom rubberized polymer finish. The most directly comparable toolset is from PBSwiss… they are the gold standard for professional Hex keys, though I feel our chrome is grippier and our polymer finish is significantly better in hand than their powder coat when your hands are greasy. Also important is that we only use the upper 40% of the ISO tolerance… so a standard 6mm is allowed to be 5.89-5.99 and we only allow for 5.95-5.99 which means our nominal target is 5.97mm compared to 5.94mm for standard hex keys.

          The durability comes from the 9 stage heat treat. We can get our particular S2 up to 62-64 HRC hardness (30-50% harder than normal keys) but at that hardness the steel can become brittle, so we step heat treat in a way that also pushes the yield strength much higher than you find in other materials. Harder stronger keys are less likely to deform and we all know the real damage comes when even mildly deformed keys are used on soft fasteners.

            Here is a comparison from our lab. This is +/-6Nm for 50 cycles in a 6/4 Ti bolt. Both hex keys were new, the black one from a very well known brand and was right ISO nominal which made it 0.3mm smaller than the SILCA. As the fastener hex and tool both begin to deform, they cause escalating damage to each other rather quickly destroying both until the tool cams out of the fastener. Sadly, if you look at the keys in your kit at home, they very likely already look like the one on the top left as it takes surprisingly little use to begin deforming them. During the original HX-One project we received 50 3-way tools from customer bike shops and found all of them to have similar levels of wear/deformation to the one in this test. Meanwhile the SILCA key is relatively unphased.

            Thanks for outlining the qualities that set these tools apart Joshua. While I initially thought these were frivolous, in practice they are a step above. In the interest of accuracy, I take it the competing key was actually 0.03mm smaller than the Silca.

            Nate, sorry, yes, omission of a zero in my post!!

      is this one?

    • Luckily, these are not one of those sets.
