Tradtional Bed Bolt
I have built 3 beds and modified another bed using these bolts and they worked well. I bought 4 bolts from another vendor but the nut was quite larger thus requiring me to drill a deeper hole so that I could use the bolt hole decorative cover plus the nut was too large. I ended up going back to Rockler and purchasing 4 more bolts. Recommend purchasing the T-handle nut driver designed for driving these bolts.

Nice hardware
Worked well. Recommend finish rail thickness of 1.25 as less requires higher skill in match up. A 3/4 forester bit to depth and chisel clearing was my method

Great!
I use the Rockler 3/8 diameter bolt on all the beds I build. The bolt is 6” long with a threaded end of 2-3/4” of that length and a square fastening nut. With careful measurement, this bolt will accommodate any 1 to 1-1/2” width bed rail

A must have if you’re building a bed with rails utiling tenons into mortised bed posts.
Don’t usd any other bolt! I was amazed how well these worked. The pointed bolt tip and the flatteNed corners on the square nuts makes for a tight and secure assembly of each bed rail.

Best thing for wooden bed frames
If your bed frame pieces are thick enough, this method of holding it together is unbeatable. Make a mortise in the leg and a tenon on the side rail. Drill out for the length the bolt, counterbore for the head of the bolt and chop out a slot for the nut. When you tighten the bolt against the nut, the joint between and leg and side rail is very very solid. We have these on all four corners of our kingsize bed and there has been zero wobbling and no need to retighten in over a decade. You cap the counterbore with either a cover made for that purpose or if you have a lathe, make a sort of mushroom shaped piece with a hollow stem to fit into the hole and over the head of the bolt. Ours is made from the same wood as the frame so it is inconspicuous. Leave it loose if the fit is good.

I designed and hand made a custom cherry wood queen bed which I was ready to use bed-rail clips. I read the reviews about bed bolts and spoke with a contact person who wrote a review that had experience. I then spoke with my brother-in-law who delivered furniture for a large manufacturer. I was advised to switch to bed bolts which I am so glad I listened because these are really solid connections that won't loosen up. They look professional and I would recommend them to anyone who has the patience and the skill to install them. I am definitely going to make my next bed project for myself with these bolts! Thanks Rockler for stocking them along with the wrench and coverplates!

I first used the bed bolts when building a massive, oak, queen-sized bed for my daughter and am currently using another set while restoring a 170 year-old Jenny Lind bed that is in very rough shape with no side rails. I'm making new rails and will use the bolts with them. Bed is originally made with walnut and basswood; new rails are basswood. I find power mitering chisel works well in setting the nuts for the bolts.

what size is square head, I have sq. sockets from my mechanic days ,wondering if I need to buy the wrench?
BEST ANSWER: I did not buy the wrench and a standard American socket set will have a socket that will tighten the bolt without any problem. I do not remember which size worked but I can check and let you know if you wish.

I bought these years ago for a beautiful cherry queen size bed. Today I finally tried to put the bed together and found these bolts to be about one inch too short so they do not reach the nut. Any ideas? Thanks.
BEST ANSWER: The nut is captured in a pocket within the bed rails, right? You would need to make a new pocket closer to the leg, or drill a countersunk hole in the outside ofthe leg into which the head of the bed bolt would fit deep enough to get to the nut in its existing pocket and yet still be able to get the end of the bedbolt wrench on it to tighten. That would best be done with a drill press. Hope this helps

I have a super king size metal bed frame that i purchased from Marks and Spencer but the bolts got lost in house move. There are two holes at each end in the bars that connect to the head and foot frames. The holes do not go right through the legs will i be able to fit these bolts to it? Thank you
BEST ANSWER: Hi Margaret,
The question indicates an awareness of how fasteners work. However, the answer to your query is in the details. I do not have the details to answer your question. I bought these bolts for a wood head and foot assembly and wood frame. They worked really well for my case. I suggest you do a wee sketch and go to your local hardware store and get advice and fasteners that will work for your steel frame and head and foot assembly. Maybe even take a piece of the metal frame with you. Good luck.

What is the diameter of the circular portion of the head?
I have a cherry bed I'm putting together it has 3/4 inch side rails will the 3/8 bolt be too big for that thickness?
BEST ANSWER: I think the nut with the 3/8 in will be too wide for 3/4 in side rail. The nut itself is 3/4 inch. I use 5/4 stock and plane it down to 1 and 1/8 inch for side rails and use the 3/8 bed bolt that you are asking about and that works well. It might be possible to get a 3/8 in hex nut that could work with the 3/8 in bed bolt and 3/4 inch rail.
