Be cautious though.. just because a Bolt's max torque is higher, does not mean that the thing it's Attached to, or Threaded Into, is suddenly stronger...
Seat Clamps, Steering Stems, Carbon Fiber ANYTHING, and Any part with Threads in Aluminum easily come to mind......

Also note that all Ti bolts are not the same strength. Cheapie bolts from unknown sources can be significantly weaker.

Speaking of titanium, I used to get various titanium fasteners from Toronto Cycles, and was quite happy with their products. Back in the early pandemic (March, 2020) the site shut down operations. Now I see that some pages appear to be working normally, while others are still in "red". Has anyone ordered from this outfit recently?
Stainless steel (L) and titanium (R) chainring hardware. Ti doesn't corrode... nice for winter commuting.

the Ti bolt i've always wanted is a Gooseneck Draw Bolt, paired with an Aluminum Draw Wedge.
the usual Cast iron wedges and steel bolts weigh a LOT.
i'd think Eroica Weight Weenies would be lining up to buy them.

You can actually see some corrosion on the "stainless" bolts.
Besides, I like the look of titanium and don't care about the weight difference.

just looked... by golly, there is now a 150mm draw bolt and aluminum 21.8mm wedge, offered separately by the same seller, in the same listing... with separate Shipping charges.... $54 total.... Weight shaved? 40 grams, 20g per part, roughly.
If the second shipping charge could be dropped, the cost drops to $48.50.... $1.20 or so per gram... that's less than many popular CF weight loss items.
last time i looked, the longest bolt offered was 110mm.

"Unavailable" and "Delayed delivery, A Bespoke item that must be custom made" was what their Cart said....
thanks anyway.
*see my post above this if interested in a Ti drawbolt and aluminum wedge*
now... back to demanding a refund for a poorly machined der. hanger that will need to be custom reshaped to fit my Specialized Enduro...2mm extra material along the front face is NOT acceptable..... i'm just glad the customer didn't have to wait for it to arrive... took 11 days to arrive... and then it 's a non-fit... ! The dirt is PERFECT right now too... nice damp loam, no mud. PERFECT. luckily, i have other options.

also note that for fasters used on bikes, the maximum torque will be limited by what the bolt is threaded into.
Like the stem face bolt or waterbottle bolt. I'd suggest no more than 6-8 Nm on stem face bolts and probably 4-6 on waterbottle bolts.
