What are the measurements of the shank and threads on the 6" carriage bolts?
Shank 5 7/8Threads 2 1/2
Unfortunately we do not have any 6" ones in stock to measure. I looked at the 4-1/2", 5" and 7" and these sizes have roughly 2.5" of thread, and the rest is shank.

I have a 5" 1/4-20 carriage bolt. The shank is exactly 5" long and thethreaded length is 2.5"? So probably the 6" is 6" length with either 3"or 2.5" threads.
How long is the thread on a 1/4-20 x 8 silicon bronze carriage bolt?
The ones I bought have 2-1/2 inches of thread.
what grade of bolts are these?
As you seem to know, steel nuts and bolts come in various grades or hardnesses that can have safety implications, depending on the use, though I could not explain it beyond that. I've never seen any "grades" noted for bronze or brass. Bronze or silicon bronze is supposedly a bit stronger than brass. I have seen 1/4 x 7 inch bronze or brass carriage bolts deform under stress, as in old style Sunfish rudder tiller assemblies. I'm under the impression people use bronze or brass when corrosion resistence, not great strength, is the goal. If you need both, stainless steel may be a better option. Hope this is helpful.
I don't think that the bronze bolts are graded like steel bolts usually are. I tightened them down pretty good when attaching some frames and they showed more strength than you would think, for 1/4" bronze anyway.
I don't believe bronze bolts are graded as are steel bolts. They are best suited to corrosion resistance around salt water and not hi strength applications.

HOW MANY BOLTS TO A BOX?
You can order individually.No need to order a box if you just need a few.
Better ask Jamestown. Small sizes may be boxed...larger sizes priced EACH. They are not cheap!
PHILIP G RASMUSSEN
It depends on the length of the bolt usually . It should show on the pricing list .
What size washers and nut would I use with a 1/4-20 carriage bolt?
1/4 ". Washer and nut and lock washer if needed.
Well---use 1/4" washer--either flat or lock and for the nut,use 1/4"x20 threads---material should be bronze in both cases.20 is the national course thread and designates 20 threads per inch.
Can i use this bolt with Aluminum ?
Only if you need a power source for your running lights :)
Only if you need a power sore for your running light :)
Short answer: NO. Longer answers: A) Yes, if your assembly will be staying in desert conditions or inside a vacuum. B) Maybe, if you keep the two metals from having any direct or indirect contact. I'm guessing you want to attach an aluminum fitting with this fastener or you are installing a fitting in an aluminum hull. In either case, you might get away with this if you isolate the metals with a rubberized gasket, make sure the connection never gets submerged in water, and ground the pieces seperately(that'll be tricky). Personally, I wouldn't do any of this. Rule number 1: keep all metals the same.
Do the bolt come with nuts or washers?
no bob they do not
BobIn answer to your question - no nuts and washers are sold seperately from carriage bolts.
bolt is naked. no nuts or washers.
No they are bolts only.
No,you must order nuts and washers separately.Word of caution---these will not take the same torque(tightening power) as steel bolts so be very careful or you will break them.You should be able to feel when they are tight.
No - you have to buy them separate.
The bolt do not come with nuts or washers.
Bob,You will need to buy the bronze nuts and washers separately. I would suggest buying the heavy duty nuts as they are more substantial and well worth the extra money. Bryon
Bob,I bought them a while ago and they did not come with washers and nuts. Not sure why they want me (a customer) to tell you this but there you have it. Good luck.-Kevin
I don't remember the nuts or washers being included with the bolts. I used wingnuts for my application, which was an easel made of mahogany.
Pleased to know the source for a product difficult to find.
I used the bolts to fulfill a function in a cabinet I am building, which needed to be decorative.
Where I live getting marine hardware is almost impossible. Jamestown has been for years my choice for quality brass and bronze bolts and screws. As pleased with selection, quality, and price.
Have old 1972 Sunfish sail boat that needs some love. hard to find part locally but Jamestown had a variety of sizes that met my needs.
