Cap Nuts for furniture
I have purchased and used these cap nuts and the bolts that go with them many times. They are well made and substantial in their application. I would recommend using this hardware to others.

Cap nuts for connector bolts
Great product. I have used them before in various projects. It makes it easier to build a large project, like an Entertainment center, in two pieces and re-assemble it on site later on.

Woodworking Experience:
a good looking fastener
I use these with the bolts that match . The bolts use a 4 mm hex tool to tighten them and these use a 5 mm hex. They add a lot to a project that needs to be taken apart at some point as the one I am working on .

BEST ANSWER: Yes, the connector bolts and cap nuts are metal.
can i use this with 1/4 #20 threaded rod?
bob w on Dec 6, 2016
BEST ANSWER: Yes=I have used these cap nuts with 1/4 #20 threaded rods on more than one occasion-screw cap nut onto one end of threaded rod, mark rod with a piece of tape, unscrew cap nut = in order to show yourself the correct length of rod up into cap nut = this will ensure you cut the threaded rod to the correct length. Good Luck!
I want to use these bolts and cap nuts to join the side panel of a murphy bed to the adjacent side panel of a set of shelves. Basically joining 2 - 3/4" plywood panels face to face. I'm not sure if the tapered end of the 1 1/8" bolt will reduce the thread engagement at the tip. Can I reach 1 1/2 inches with the 1 1/8" bolt and cap nuts, or will I need to cut down a 2" bolt?

BEST ANSWER: I had a similar issue and ultimately used longer bolts and cut them to the desired length.
I'm wanting to connect a vintage wood headboard and foot board to some shelving units to create a platform bed. The shelving units are made of particle board. The shelving units and bolts will be holding the headboard and foot board upright. The four shelving units will be supporting the bed slats and distributed weight of the mattress and people, but the bolts won't be supporting that weight. I'm thinking of putting two bolts at each joint, one above the other. Do I need to do something to reinforce the particle board at the joints? Do I really need two bolts at each joint?

BEST ANSWER: Martha: I've used the connector bolts on shelving with good success, and would say if you plan on using them to connect your shelving units just to keep them in place, and you have adequate thickness, then you probably wouldn't need to add further support. If the particle board is thin, say less than 1/2", you may want to back up your connections with a plywood washer. good luck
are the black oxide connector bolts suitable for exterior conditions ?
tony s on Jul 8, 2016
BEST ANSWER: I would not use these outdoors. You could paint them with rustoleum or something equivalent.
Do the Cap Nuts have to be epoxied in place to prevent 'spinning'?
Richard D on Apr 9, 2016
BEST ANSWER: I used these for a wood panel I wanted to be able to remove easily. I did not secure these connector bolts with any adhesive and they seem to tighten easily by holding the back side with my hand until they pull tight. After they tighten up they don't slip. To remove I sometimes have to put a little pressure on the back with my hand but generally they just unscrew without much trouble. Note that I am securing two pieces of wood for materials that may be very hard I don't know if they would slip. Also, I have easy access to both sides which makes it convenient to put pressure on the back side if needed.
What is the thread depth of these nuts?
A shopper on Jul 17, 2015
BEST ANSWER: Good evening,History of use: I use Cap Nuts as splice bolts for joining cabinets together with the intent of being able to take the units apart if they have to be relocated. To answer your question, I usually join two three quarter inch sections of plywood (panels) together for most of my cabinet work. Keep in mind when selecting Cap Nuts, you must determine the thickness of the material you are going join together, this determines the length of the nuts as well as thread length. As I have pointed out, I usually bond two three quarter inch sections together therefore, the threaded section is approximately five eights of an inch in depth. One additional thing I need to point out is one Cap Nut section (female) is larger in diameter then the (male) Cap Nut section, therefore, when drilling the pilot holes you need to take this into consideration. I usually use a “Hole Templet Sizing Tool” to choose my drill bit. Selection of which side of the panel for the larger pilot hole doesn’t matter as long as the mating hole (opposite hole (male)) is slightly smaller. As a reminder, the thread depth is determined by the length of the Cap Nuts, you choose. One note that may help you, I use a fostener bit, to make a slight recessed hole on both surfaces for the head of the Cap Nut, in order to be flush with the panel surface. Makes nice detail work and illustrates your professionalism in wood working. I hope this helps.
Black oxide - I want to use them on a exterior handrail. Some people used these on exterior furniture, did it rust on you at all? One person suggested spray painting them, but that adds a lot of labor on 100 fasteners. Thanks!
