The fastener cluster you reach for first when a bike's stopping power, shifting, or cockpit needs adjustment, all on a single Y-handle that spins each size in one rotation.\u003c\/p\u003e\n\u003cp\u003eThe three-way (Y-handle) format puts T10, T15, and T25 at 120-degree spacings around a central pivot. Each tip is on its own dedicated arm, so you're never chasing the right size in a bit holder or hunting for a separate driver. The Y-geometry also gives you a third axis of leverage: pull on two arms while the third sits in the bolt, and the tool rotates without slipping.\u003c\/p\u003e\n\u003cp\u003eThe shanks are chrome-vanadium steel, hardened and tempered, with black-oxide tips for corrosion resistance and a tight fit into Torx recesses. The handle is glass-fibre-reinforced polypropylene, light enough to be quick between fingers and durable enough to live on a workshop bench.\u003c\/p\u003e\n\u003ch2\u003eWhat it's for\u003c\/h2\u003e\n\u003cp\u003eT10 lands on small electronic-shifter fasteners and some derailleur cable-anchor bolts. T15 covers SRAM brake-lever clamps on some models and chainring rivet hardware. T25 is the size that built modern disc-brake maintenance: every 6-bolt rotor in the industry uses six T25 bolts in a hexagonal pattern. If you ride disc brakes, the T25 arm on this tool will see the most use of any single driver in your kit.\u003c\/p\u003e\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eT10, T15, T25 Torx sizes on a three-arm Y-handle\u003c\/li\u003e\n\u003cli\u003eChrome-vanadium steel shanks, hardened and tempered\u003c\/li\u003e\n\u003cli\u003eBlack-oxide tip treatment for corrosion resistance and Torx-recess fit\u003c\/li\u003e\n\u003cli\u003eTrivalent chrome plating to ISO 1456:2009 on the non-tip shank surfaces\u003c\/li\u003e\n\u003cli\u003eGlass-fibre-reinforced polypropylene handle\u003c\/li\u003e\n\u003cli\u003eManufactured in Slovenia\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eBuilt in Zreče, Slovenia\u003c\/h2\u003e\n\u003cp\u003eUnior has been forging hand tools in Zreče since 1919, and sponsors professional road and mountain-bike race teams. The three-way wrench's Y-handle geometry isn't a one-off cosmetic choice; it's the same construction Unior uses across the pro-shop hex and Torx line, with the same chrome-vanadium shank and black-oxide tip treatment. The consumer Y-handle isn't a downgraded version of the shop set; it's the shop set in a Y-handle format.\u003c\/p\u003e\n\u003ch2\u003ePro tip from our mechanics\u003c\/h2\u003e\n\u003cp\u003eWhen you reach for T25, you're almost always on a rotor bolt. The torque spec from rotor manufacturers usually lands at 5–6 Nm, which is tight enough that a Y-handle's leverage will easily overshoot if you crank on it. Snug it down with the Y-handle, then finish with a torque wrench and the matching Torx bit if you want to hit the published spec exactly.\u003c\/p\u003e\n\u003cp\u003eFor more on when T10, T15, and T25 are the right call vs. T30 (which lives on most modern chainring bolts) and the T20 \/ T27 \/ T30 sizes that show up less often: \u003ca href=\"\/blogs\/tech-tips\/hex-and-torx-wrenches-how-to-pick\"\u003eHex and Torx wrenches: how to pick the right tool for the job →\u003c\/a\u003e.\u003c\/p\u003e","brand":"Unior","offers":[{"title":"T10, T15, T25 Torx","offer_id":44140758630444,"sku":"624911","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0012\/5786\/5260\/files\/1781_2tx-us_624911_image_1024.jpg?v=1745317777","url":"https:\/\/uniorusa.com\/products\/three-way-wrench-t10-t15-t25-torx","provider":"Unior USA","version":"1.0","type":"link"}
