For the 3/16" bolts, what is the diameter of the bolt heads? Are they 5/16" or less? Asking again since they can't also be 3/16"

Diameter of the head for the bolts included in box it's pretty close to 6/16, I'd say 11/32.

No, they are hex head bolts, standard thread and 5/16" diameter. Longer than 2", probably 3".

3/8" is smaller than 1/2". These fit .22lr rails, or the dovetail underneath old mosin rear sights. I doubt your bolt-on rail is 3/8", but if you posted a link to the mount you bought maybe we could check it out and see.

Mine is 2 1/2"X2 1/2". It has extra holes to accomidate your 3" side, but mine has the 2 1/2" shims that slip over the bolts. So unless you cut them down, I would say no. Hope this helps.

Hello Richard, I purchased this set of fasteners about 2 months ago, the bolt selection goes up to 16mm (5 different lengths of 16mm) it is perfect for my small shop, however, depending your need, this assortment maybe too small for you. Good luck, take care. Wayne

Oh man....i just put them in two months ago. I want to say it was 1/2".... I have a chrysler 8.25" rear and had to open up the hole a wee little bit but for the life of me i cant remember what size bit i used. 80% sure it was half inch.

They are short, threaded, heavy hex head bolts and washers that screw in from the bottom. Not sure of the size, but I'd say appx 1/4" - 3/8ths" diameter maybe?

Well, they are 6.5, but overall is 6.75. Reason why is. They fit into a 6.5 mounting hole/bracket, an there's just a bit of a lip, but that's for mounting purposes. Me & my girlfriend have a pair of these is our vehicles & there great. Hopefully my info helps. Or if you need more info, you can ask :-)

Bolt holes are 1 3/8" center-to-center. Be aware that holes are chamfered so need flat head bolts. Holes are 3/8" dia. at bottom - about 9/16" at top. Blades are 1 3/16" wide x 2 1/4 long. About 1/8" thick. That's probably more than you needed to know, but hope that helps.

A 2 1/2 to 3 in. lag bolt works great. I used a washer as well, but probably not necessary. Have fun!

The ones I received were 3/8-16 threads per inch! I used them on a big stainless steel Bar-B-Que with 3/8-16 nuts and locking washers.

Purchased through Amazon, it appears that they are grade 8.8, which I now understand is equivalent to SAE grade 5 (thanks for the clarification, A. Baldwin!!) The nuts have "|8|" stamped on each of them, and the bolts have "8.8" stamped on the heads. The description should specify "Grade 8.8" instead of simply "Grade 8."

The manual says to use a 3/8" bolt. Not sure if a larger bolt will also work.

They are 3/4". They should fit fine. They are a actually one size too big for My machine. They are still in the box.

They r 2" X 1/4" lag bolts. I did not use them & purchased some 3" self drilling screws that had washer head & star drive.

the bolts are 1/4 size, this is a propriety size slot. The sliding nut is 1/8 thick and 1/2 wide.
