Colt says recommended drill size is "LISTED" as 11/32". Where might an inquisitive person find th...

Asked by Bee March 17, 2021

Answer

It is not listed on the website, since different wood application will require different drill sizes. However for soft wood application and a 1/4 insert nut, 11/32" is the industry recommended drill size.

Answer

You can make a 1/4 in. pilot hole for hard wood, or a 15/64 in. pilot hole for soft wood.

What are these made out of? The description says: steel construction, zinc plated. Then why won't a magnet stick to it?

True. I suspect the "steel" is "potted metal" and. as such, is weak in tension [a load not applied]

IS THESE WORK ON CONCRET

Asked by TAVIO January 7, 2016

Answers

Nothing I read mentioned concrete. Looks like they are designed for wood, plastic and other soft materials because the inserts are soft. There are concrete anchors to use for concrete.

I am having trouble finding bolts that fit these insert nuts. Any specific suggestions?

They are designed for 1/4 inch - 20 threads per inch SAE bolts. Normal designation is 1/4-20 SAE. They are not metric.

1/4 in. - 20 tpi x 20 mm Zinc-Plated Steel Type-D Insert Nuts These look very well made and the teeth are sharp. I have not used them yet but have a project planned for them. There is a good tight 6mm hex key socket for driving them in and if you only have inch keys a 7/16" will work but it loose. Length is a full 3/4" and the head is 15/32" diameter.. Use the recommended drill size and insert will drive in fairly easy and the teeth will have a full 1/32" bite providing plenty of hold. I tried an assortment of 1/4 -20 SAE bolts and they all turned easily with minimal play. HINT: take your time drilling square and inserting them square.

The 1/4 inch - 20 TPI by 20 millimeter Zinc-Plated Steel Type- D Insert Nut is what I needed to replace the cheap pot metal insert nuts that came with my dining room Chairs. The Zinc - Plated nuts firmly hold the legs to the seat base after removing the broken pot metal Insert used by the chair manufacturer. Being made of steel, the replacement nuts should last a long time.

bad information
I used these on birch plywood. I drilled a 5/16 hole and used a 6mm Allen wrench and they worked fine. I tried a 1/4 in wrench and it stripped the drive right away. These instructions should be written on the pack and not have to be figured out by the purchaser. Do your job Home Depot!!!

perfect fix for my car brake cable bracket
My old car’ parking brake cable broken and the hold down bracket bolt rusted and broken ofcourse during removing,. There is only a bolt hole in the underneath the car and I could not find a good way to attach the bracket to that hole. This insert is a life saver, I just hammer it into that hole, and use a bolt to attach the bracket. Since the brake cable is quite light, this should work and hope to last many years

This insert nut works quite well for light duty applications. I used it and needed to pre-drill the hole to insert it. You must take care in installing it to be square to the finish or your bolt will be off by a particularly unacceptable degree angle. Using a hex key in a drill or a t-handle or those hex key bits for ratchets is ideal for leverage apart from small hand held hex key wrenches.

These are great anchors for wood projects. Just make sure you drill the correct size hole for them to work correctly.. When inserting them into the wood I put a bolt with a nut all the way to the head and then seated that in the anchor. Then used a socket to turn it into the wood. I used these when building a bunkbed for my granddaughters. These made it easier to disassemble and reassemble.

This is a review of Everbilt's #608576 insert nuts [four to the package]. These inserts are primarily used for building or repairing knock-down furniture/assemblies and, quite honestly, not those that will take repeated abuse [for which you might opt for t-nuts]. But that limitation is inherent in the design, which is somewhat generic. [I last used to reattach a leg on an ottoman that had snapped off.] The directions are clear and should be followed. I wouldn't use these in MDF; they can be used in pine, but they'll be strongest in hard woods [poplar, oak]. While I said the design is somewhat generic, there are some unique features that I like and one feature that could prove problematic. First, the barrel is tapered to allow for ease in centering, call it 'self-aligning'; you'll meet growing resistance as it's driven deeper as the upper portion of the barrel will exert lateral/compressive forces on the hole you've drilled [more pronounced in hardwood]. Second, the cutting grooves around the barrel are [unlike the illustration] not continuous but 'skip toothed' ... which may help in clearing the grooves being made. Lastly, and what I don't like ... the top is flanged; it'll require a lot of force to drive it flush to the surface. Note: the illustration of Step #2 seems to imply you can hammer in these; you cannot. These nuts can only be driven by a 6 mm hex key; and to make life simplier, use a straight t-handle hex key and not a bent hex key; for perfect alignment you may want to chuck up a kex key but move slowly. There is no screwdriver slot in these nuts.

I've built two different quilt racks with these. I amazingly only had one strip out the wood around it while building the first. I thought it was just user error. Upon building the second quilt rack, I stripped out two insert nuts right away. I had to stop to figure out what was wrong. Essentially, some of the insert nuts are well made and bolts thread easily through. However, on about half, while holding the insert nut by hand and trying to screw in several different bolts, each locks up, causing the nut to chew through wood that has been precisely measured and made to create furniture. Very disappointed. I'm glad I bought an extra pack because each 4 pack contained half duds and half good insert nuts. Will not buy again.
