While you can likely use a HEX key that came with your Ikea shelf and has been in a junk drawer for years, we'd like to point out that a better tool fit creates a better tool feel and more confidence for the mechanic. This significantly reduces the chances of damaging fasteners on high-end parts. The #SILCA HX-One hex keys are made from the finest S2 tool steel for the optimal balance of strength, hardness, shock resistance, and dimensional control. Our keys are then coated with thin-dense chrome and a high-grip, high-visibility textured polymer finish for maximum grip and control. Organized nicely in a wooden CNC'ed box. Plus, you can use these for your Ikea furniture too. Photos: @garethwinter
