BOLT DISC TO HUB TRIUMPH T140/150 - 3/8-24 unf 4 1/2 UH (14-0243)
3/8-24 UNF bolt, 4 1/2 in., for mounting the front brake disc to the hub on Triumph T140/T150 models.
This is the bolt that secures the front brake disc to the wheel hub on Triumph T140 and T150 machines, showing up in the front wheel section of the parts book for the 1979 model year. It's a 3/8-24 UNF bolt, 4 1/2 inches under the head, the size you need to clamp the disc solidly to the hub flange without stacking up thread or length problems.

This part also carries the older 14-0243 number, so if you're working from an earlier parts book or have a bolt in hand stamped with that reference, it's the same physical bolt as 21-2207.
These bolts take real clamping load holding the disc flat against the hub, so it's worth checking condition and thread before reusing an old one. Give us a call if you want to confirm this is the right one for the disc and hub combination you're working with.
