Interestingly, Kevin Rodel uses a stub tenon only 1/2 inch long ( and a 1/2 thick ) for the rail joints using bed bolts. His rails are for a queen bed, they are 7 inches and he uses a 6 inch stub tenon. If your rails are 8 inches, you could easily use a 6 inch tenon. Any reasons that he used 1/2 stub tenons for the rails? The joint relies on the bed bolt to pull it tight so you do not need any real tenon length ( because it is not a glue joint )?
I covered my bed bolt with medallions

The bed rail fasteners in the queen size bed my son and his wife sleep on is more than 20 years old and the bed has been moved several times. It is still solid. My late wife and I slept on it about 20 years and my son and his wife have used it daily 7 or 8 years now. It is made of oak. If you make a good snug mortise for the plates and use 2 inch or longer screws I am pretty sure you will have no issues. I think the main issue is if you use too short a screw into the end grain of the rail. Those screws in particular have to be long because the holding power of the end grain is not great. 3 inch would be good and since the rail is so long there is no reason to use a shorter screw. In the headboard and end board you probably cannot use a 3 inch, I couldn't. In one design I have made three times now (including my son's), the legs are 3 inch so you can use a 2.5 inch screw. Another design I've made twice has only 1 3/4 inch material in the legs so you are limited to about a 1 1/2 inch screw. Those beds are doubles but have held up fine with couples in them occasionally. I sleep on one of these beds when I visit them. It is very solid.
I am not saying this is the only joint that will work. Many will work. But these fasteners are the easiest to use I have found that make a good solid bed. I have no interest in making a bed that will not hold up. The other advantage is they do not show when the bed is assembled.

I was thinking about the hidden bed bolts as pictured above. Or flip the common type around. And I 'thought' Benchcrafted had something like that for their bench kits. But they're the conventional exposed style using a barrel nut.
My personal concern would be with using them with the rails flush with the inside of the post. The notch and pocket for the screw more or less forces you into putting the thread insert 5/8" from the face of the post. Seems kind of close to me. If the rail were set in (out actually, I guess) you'd have more meat there for the insert.
Agree. I'm going with all bed bolts now. and going to mortise/tenon all rails and position them in the center of the 3 3/4" square posts. The headboard bed bolts will pass all the way through the posts, because I don't care if a bolt is exposed on the back of the headboard. The 2 footboard bed bolts will be concealed. If I drill (7/16 hole) it in the center of the tenon, for the bolt, I think I'll have plenty of wood on either side of the bolt.

These are the bed bolts I bought. Bed bolts. But now I'm wondering with the size of the rail (8" x 1 1/4" x 82"), whether I should use 2 bed bolts per connection. Or, would 1 bed bolt be sufficient ? Would the 2 bolts weaken the tenon? I was planning on a stub tenon ( 3/4" thick x 5 1/2" width and length around 1 1/4"). Does that seem too long for a stub tenon ?
I've made a bunch of queen sized beds. I used the hook/plate hardware on the first one and never used it again. (Those beds rack as you move them around and can squeak with "vigorous bouncing".) I now use tenons on the ends of the rails about 1/2" long and the full width of the bed rail (minus a small shoulder). The stub tenon serves to make sure the holes in the leg and rail are registered and makes assembly of the bed easier. I clamp the bed together then drill holes for 2 bed bolts for each rail connection. I either leave the heads exposed or hide them in a counterbore covered with the same wood as the leg. These beds could be dropped out a 2 story window and not rack. They do not squeak regardless of how much vigorous bouncing they are subject to.
Minutiae brings lots of opinions! When I was a kid I worked for an old guy who was still mad about the Great Depression....the one with no
prescription pills. He insisted bed rail stub tenons be 1and 1/8. “Most go shorter, but MY way makes it easier to put the bed together if you
are working alone”.
The problem with the world is that intelligent people are full of doubts, while the stupid ones are full of confidence.

When I built my daughters bed.. bought "bed bolts"... the threads were not standard... if someone took it apart to move it and lost the nut, they were in deep trouble...
Returned the "bed bolts" and used 3/8" x 7" standard galvanized bolts with a flat washer on each end...
2 advantages:...
first is if a nut is lost, it is easily replaced..
second is that you can use any standard socket to install them.. do not need a special wrench..
I used the brass covers on the holes...
