While internal hex sockets easily round off under high-torque rotor installations, our Torx T25 star drive provides 100% positive radial engagement. It distributes torque across six symmetrical contact lobes, eliminating driver cam-out and preserving tool interfaces through countless brake pad and wheel swaps.\u003c\/p\u003e\n\n\u003ch3\u003eUltra-Low Profile 9.5mm Flanged Button Head\u003c\/h3\u003e\n\u003cp\u003eWith a low-profile 3.0mm head height and an integrated 9.5mm wide flange, these bolts provide generous clearance against fork lowers, caliper adapters, and quick-release \/ thru-axle dropouts. The wide flange acts as a captive washer, distributing clamping force across the rotor carrier without galling or warping lightweight multi-piece floating disc spiders.\u003c\/p\u003e\n\n\u003ch3\u003eRotating Unsprung Mass Reduction for Faster Wheel Acceleration\u003c\/h3\u003e\n\u003cp\u003eWeight removed from the wheel hub constitutes rotating unsprung mass—the most influential weight reduction on a bicycle. At approximately 1.2–1.8 grams per bolt, a full set of 12 titanium rotor bolts (6 front, 6 rear) cuts hardware weight by ~45% compared to OEM steel screws. This reduction noticeably sharpens rotational acceleration, climbing response, and suspension compliance over rough terrain.\u003c\/p\u003e\n\n\u003ch3\u003eThermal Stability \u0026amp; Severe Weather Immunity\u003c\/h3\u003e\n\u003cp\u003eBicycle disc rotors frequently reach 200°C–300°C during sustained descents. Certified Grade 5 (Ti-6Al-4V) titanium delivers superior thermal stability, retaining its 950+ MPa tensile strength without heat fatigue. The natural self-healing titanium oxide film ensures complete immunity to rust, trail mud, winter road salt, and aggressive bike wash detergents.\u003c\/p\u003e\n\n\u003ch3\u003eRotor \u0026amp; Frame Compatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e6-Bolt Disc Rotors:\u003c\/strong\u003e Direct fit for all standard 6-bolt ISO 44-hole pattern rotors (Shimano, SRAM \/ Avid, Magura, Hope, Formula, TRP, Hayes, Galfer, Campagnolo, Ashima).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBicycle Frame Mounts:\u003c\/strong\u003e Perfect length and profile for water bottle cages, fender mounts, and fork cargo bosses.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications \u0026amp; Dimensions\u003c\/h3\u003e\n\u003cp\u003e\n  \u003cstrong\u003eMaterial:\u003c\/strong\u003e Certified Aerospace Ti-6Al-4V (TC4) Titanium Alloy, Grade 5\u003cbr\u003e\n  \u003cstrong\u003eThread Size:\u003c\/strong\u003e M5\u003cbr\u003e\n  \u003cstrong\u003eThread Pitch:\u003c\/strong\u003e 0.8mm (Standard Metric Coarse)\u003cbr\u003e\n  \u003cstrong\u003eHead Style:\u003c\/strong\u003e Low-Profile Flanged Button Head\u003cbr\u003e\n  \u003cstrong\u003eHead Diameter:\u003c\/strong\u003e 9.5mm\u003cbr\u003e\n  \u003cstrong\u003eHead Height:\u003c\/strong\u003e 3.0mm\u003cbr\u003e\n  \u003cstrong\u003eDrive Type:\u003c\/strong\u003e Torx T25 6-Lobe Star Drive\u003cbr\u003e\n  \u003cstrong\u003eWeight:\u003c\/strong\u003e ~1.2g (10mm), ~1.5g (12mm), ~1.8g (15mm)\u003cbr\u003e\n  \u003cstrong\u003eAvailable Lengths:\u003c\/strong\u003e 10mm (Standard Disc Rotor), 12mm, 15mm\u003cbr\u003e\n  \u003cstrong\u003eAvailable Finishes:\u003c\/strong\u003e Natural Titanium, PVD Vacuum-Coated Gold, Rainbow, Burn Blue, PVD Deep Black\n\u003c\/p\u003e\n\n\u003ch3\u003eInstallation \u0026amp; Torque Guidelines\u003c\/h3\u003e\n\u003cp\u003eClean hub threads thoroughly before installation.
