Water-bottle cage bolts shrouded by a rear rack. The bolts on a bike where straight-on access is blocked, on a Y-handle whose ball-tip ends engage the bolt at an angle.\u003c\/p\u003e\n\u003cp\u003eThe ball-tip geometry lets each arm engage the hex recess at up to about 25 degrees off-axis. That's the geometry that makes a ball-end wrench the right tool for \u003cem\u003efinding\u003c\/em\u003e a bolt and breaking it loose when a frame, cage, or component blocks straight-on access. The three sizes on this Y-handle (4, 5, and 6 mm) are the most common medium-hex sizes on a bike, which is why this is the angled-access tool most likely to live on a workbench rather than in a drawer.\u003c\/p\u003e\n\u003cp\u003eThe shanks are chrome-vanadium steel, hardened and tempered, with the ball-tips finished to a precise spherical radius. The polypropylene handle balances the three-way geometry; you can spin a bolt with one arm in the recess and two arms rolling between your fingers, while the ball-tip lets you do that from an angle a straight-tip wrench would refuse.\u003c\/p\u003e\n\u003ch2\u003eWhat it's for\u003c\/h2\u003e\n\u003cp\u003e4 mm hex covers stem face-plate bolts on many bars, brake-lever clamps, and the bottle-cage bolts most road and gravel frames use. 5 mm is the size for stem steerer-clamp bolts, seatpost binders, and saddle-rail bolts on most clamps. 6 mm shows up on disc-brake caliper-mount bolts and some chainring bolts on older designs. The ball-tip format earns its place anywhere the bolt sits behind something the driver can't pass through: behind the bar bend, behind a rear bottle cage, between a frame stay and a crank arm.\u003c\/p\u003e\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e4, 5, 6 mm ball-tip hex 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\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\u003eBall geometry engages bolts at up to about 25 degrees off-axis\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.

It's the wrong tool for the final torque pass. Once the bolt is in the recess and turning freely, switch to a straight-tip Y-handle or a T-handle for the snug-down: the ball-tip's contact patch is small, and concentrated torque on a small patch is exactly the geometry that rounds the recess flats.\u003c\/p\u003e\n\u003cp\u003eFor the line between ball-tip and straight-tip, the working-torque threshold our shop uses to decide between the two, and when the 4 \/ 5 \/ 6 mm cluster needs a torque-wrench bit instead: \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":"4, 5, 6mm Ball-tip Hex","offer_id":44140759384108,"sku":"624910","price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0012\/5786\/5260\/files\/1781_2hxs-us_624910_image_1024.jpg?v=1745317958","url":"https:\/\/uniorusa.com\/products\/three-way-wrench-4-5-6mm-ball-tip-hex","provider":"Unior USA","version":"1.0","type":"link"}
