ive been searching for carriage bolts, but it looks like they dont make any in titanium, cause i just need some really strong ones that hold alot of weight without bending (about 250-300 lbs), i dont know if they make any that will fit my needs but any help would be great, thank you

EDIT: they have to be 1/2 inch thick in diameter and at least 10-12 inches long...

Try McMaster-Carr. They might not have Ti. but they will have the strongest commercially available carriage bolts. Although I've personally lifted Cat diesel engines with 5/16" grade five bolts. As important as the bolt strength is, the back-up washers or plates are also critical, as well as the bearing dimension of the nut. Good luck. I just checked McM./Carr and the best they can do is an 8 in. stainless c.b. in 1/2". You may wind up with long square head bolts and flat washers, unless you can use all-thread.

Grade 5 Carriage Bolts

Most bolt strength charts show tensile strength per square inch. A half inch bolt is not half of a square inch. The tensile (breaking) strength of a 1/2 inch grade five bolt is about 17000 lbs. A grade 8 1/2 inch bolt has a tensile strength of about 21000 pounds. You did not say how the bolts would support the load but grade five and certainly grade eight bolts should do the job for you.

Just going by sheet numbers AISI Carbon Steel - AMS 5046 - Ultimate Tension = 55000 psi AISI 301 Stainless Steel - AMS 5901 - Ultimate Tension = 73000 psi Ti-5Al Titanium - AMS 4901 - Ultimate Tension = 120000 psi There are a lot more versions of Carbon, Stainless, and different Titanium alloys, but those are just a few numbers. I would recommend looking at the MMPDS-02 spec if you want more information.

Try this:

According to this chart, the tensil strength, pulling the direction of the bolt length, are shown per sqaure inch. So a half inch grade five bolt would hold more than you need. Now shearing strength, the sideways strength is much less.
We hung cooling units that our forklift could barely lift with half inch all thread, one on each corner.

I don't have the slightest idea what you'd need a "Titanium" bolt for but, the medical industry uses them. I have 48 "Titanium" screws in my body holding plates and other things together in me.
I don't know where you'd get them though only, they do make them. Contacting a medical supplier may help.
