{"product_id":"chroma-12-disc-brake-rotor-bolt-kit","title":"Chroma 12 Disc Brake Rotor Bolt Kit for MTBs and Road Bikes","description":"\u003cp\u003eLooking for replacement disc brake rotor bolts? The NAC Chroma 12 is a twelve-piece set of T25 rotor bolts in M5 × 10mm — the standard size for 6-bolt disc rotors — with enough in the pack to do both wheels. Rotor bolts are the fastener most likely to round out on a home workshop job: they sit torqued tight against a hot rotor, they seize in place over a monsoon, and a worn hex key turns the head to mush. These use a T25 Torx drive, which bites deeper into the head and resists cam-out far better than a hex socket of the same size.\u003c\/p\u003e\n\u003ch4\u003eBest For\u003c\/h4\u003e\n\u003cp\u003eRiders replacing rounded, rusted, or mismatched rotor bolts, and anyone fitting new rotors who wants the hardware to match the rest of the build. Twelve bolts cover two 6-bolt rotors, so one kit does a complete bike front and rear. If your hubs are Centerlock — where the rotor is held by a splined lockring rather than bolts — this kit isn't the right fit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwelve bolts, two rotors\u003c\/strong\u003e — a complete bike front and rear in one pack, rather than buying twice.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eT25 Torx drive\u003c\/strong\u003e — six flat lobes grip the head far better than a hex socket, so the tool is much less likely to slip and round the bolt when you're backing out one that has seized.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreadlock pre-applied\u003c\/strong\u003e — every bolt carries a threadlock patch from the factory, so it resists backing out under braking vibration without you adding anything on first fitting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard M5 × 10mm fitment\u003c\/strong\u003e — the size used by 6-bolt rotors across every major brand.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlloy steel\u003c\/strong\u003e — rotor bolts carry braking load through constant heat cycling, and alloy steel is the standard material for the job because of its tensile strength.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour colours\u003c\/strong\u003e — red, blue, purple, and gold, so your rotor hardware can match your frame decals, your hubs, or the rest of your bolt kit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect replacement\u003c\/strong\u003e — swaps straight in with a T25 key, no adapters and nothing else to change.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eWhat's in the Box\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e12 × NAC Chroma T25 disc brake rotor bolts in your chosen colour\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 12 bolts (6 per rotor, covers two rotors)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e M5 × 10mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive:\u003c\/strong\u003e T25 Torx\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Alloy steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreadlock:\u003c\/strong\u003e Patch pre-applied to every bolt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e 6-bolt disc rotors only — not Centerlock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColours:\u003c\/strong\u003e Red, Blue, Purple, Gold\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eInstallation\u003c\/h4\u003e\n\u003cp\u003eRotor bolts work loose more readily than almost any other fastener on a bike, because braking puts them through constant heat cycling and vibration. Chroma 12 arrives with a threadlock patch already on each bolt, so don't add liquid threadlock on first fitting — the patch does that job, and extra compound over the top can stop the bolt seating properly. Clean the threads in the hub, fit all six loosely before tightening any of them, then work round the rotor in a star pattern, opposite bolt to opposite bolt, bringing them up evenly over two or three passes so the rotor seats flat against the hub flange. Finish to the torque figure specified by your rotor or hub manufacturer — most fall between 2 and 6 Nm, lower than riders expect — and check them again after your first ride or two.\u003c\/p\u003e\n\u003cp\u003eTwelve bolts, two rotors, one bike.
