E-Z LOK 400-3-CR Threaded Inserts for Wood, Installation Kit, Stainless Steel, Includes 10-24 Knife Thread Inserts (6), Drill, Installation Tool

I recently built myself a custom Stratocaster with a black limba body and solid rosewood neck from Warmoth. These guitars are referred to as having bolt on necks when they actually use wood screws. That term has always bothered me. For a better, more solid connection these inserts are perfect and the guitar will actually have a bolt on neck. A solid neck to body connection is crucial for tone transfer and this method is considered superior to just using wood screws. It's a little tricky getting everything aligned properly before drilling the holes for the inserts but measure twice and drill once is the way. Clamp the neck to the body and use the e strings as alignment guides and you can't go wrong whej pre-drilling the holes for the inserts. I recommend gluing these inserts in with a good marine epoxy for maximum hold.

I was using these for river table legs, to insert into VERY hard hickory wood. The 25/64 bit was VERY snug. Had to open it up to 13/32nds in some spots. What I found worked best was a stainless steel 1/2" inch bolt to put them into the wood. Save the special proprietary tool for when you mess up and need to pull one out. The brass inserts are very prone to chipping with too much torque on the EZ Lok insertion tool, but the 1/2" 1/4" 20 bolt worked well to insert. I would buy again now that I know how to use.

Bought this to install SS threaded 8-32 inserts for a project. Easily installed inserts in Yellow Birch and Yellow Poplar. Would definately buy again.

Good kit for adding threaded inserts. Steel insert is nice and strong. Accompanied drillbit takes out the guess work for right size to drill.

The kit is not worth the money. The installation tool broke the first time I used it and almost got permanently lodged into the threaded insert. Additionally the 25/64 drill bit is not big enough for hard wood (bamboo in my case). I assume 25/64 would be fine for softer woods.Instead just go buy a stainless steel machine screw ($2 for 4 — avoid using nickel or brass) and use that to insert the threaded inserts into the wood. For hardwood use a 27/64 drill bit.The stainless steel threaded inserts are VERY GOOD, so just go buy the 10 pack for half the price.

If you need to install threaded insets in hardwood this is your answer. Nothing works as well as this does!

These worked great for the project I had. They went into cherry and ash just fine. Definitely recommend this kit if it's your first time. The driver is a lot easier than using a screw driver bit.

I bought a used Tele and someone had installed an oversized Sheetmetal screw in the neck mount. Stupid-head! Anyway after installing these my guitar looks and functions perfectly.

Used on a wooden deck to secure a canopy.Easy to use but you must be careful to get the insert straight.

The insert driver works very well.VRB
