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!

All of these items (3/8' Dia. Bed Bolt, Bed Bolt Wrench, Bed Bolt Covers, Sheraton Style Antique brass, Cross Dowels and Connector Bolts) were purchased to build a bed for our youngest daughter a project that is on hold until I recover from Rotator Cuff surgery three days ago. They all are exactly what we were looking for,were well packaged are great value for the cost.

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 Bed is originally made with walnut and basswood; new rails are basswood.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.

My bed was an old (1960's)which was assembled with dowels and glue. The glue was old and brittle, so that the joints were loose. Installation of the bolts solved the problem.

I have used bed bolts on a number of beds I made. They secure better and more rigid than any other means. The wrench tightens well and looks good. I attach it to the headboard so it is always available to tighten or disassemble the bed.

also needed this for a bed project
Lee J on Jun 17, 2018
I purchased these as the bolts for my threaded inserts that I will use to connect the head and foot boards to the side rails. I may use the nut instead of the threaded inserts, but am reluctant to make another cut in the rails as the bed is well over 150 years old and has been restored using several wood patches so to speak. We'll see.

ROBERT B on Aug 14, 2017
I have built several beds, all utilizing these 3/8" diameter bed bolts. When used in conjunction with dowels, these bolts provide a strong assemblage just the way old craftsmen use to build.

I am hoping this will do the trick, as I purchased a very early rope bed that was converted to hold today's mattress and two of the bolts were missing.

I prefer this bolt over all other methods of securing bed rails. Call it "Old school", but this has served me well for years and never failed.

what size is square head, I have sq. sockets from my mechanic days ,wondering if I need to buy the wrench?
A shopper on Aug 27, 2015
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 recently purchased ..n awesome antique bedlooks a little french inspired. got the head and foot boards and wooden side rails, but there a inner grove allowed a stability rod. can just bolt through headboard but fut board has about 3"x1" slot and inside that a rod runming acros as to the rod actually hooking in this end. so far havent seen anything like it
Any idea?
karen b on May 18, 2015
BEST ANSWER: Hi there are so many variations in these beds that have to be considered it would be helpful to have a picture of thisI just did the same thing had to dig out wooden plugs and replace the old nuts as the new bolts had different thread pitch
Where can I just purchase the nuts for the bolt?
A shopper on Apr 17, 2015
BEST ANSWER: You can purchase 3/8" x 116 tpi Square Bolts at many local hardware stores. They are also available from Fastenal.com.
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.
Finster on Jan 9, 2016
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
Margaret L on Jan 31, 2017
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.

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?
Mike P on Jan 24, 2018
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.
what's the physical dimensions of the nut?
ronald c on Sep 5, 2017
BEST ANSWER: Sorry, I don't have it in my possession anymore but it's probably about 3/4".
