Best Nut Inserts of 2025

"I found these thread inserts to be the best value for my 3D printing projects. All I needed was my soldering iron and some patience to make everything work together perfectly!"

"These inserts are of top quality for the price and they met my needs perfectly. Plus, the delivery was very quick!"

"Having never used inserts before, I was pleasantly surprised by how easy they were to install. They hold really well in PETG, much better than regular nuts."

"I found these inserts to be beautiful and easy to use. They included the Alan wrench and the perfect size drill bit. Just drill the hole, insert the piece, and drive it in. The connection is very strong with the 1/4" -20 bolts I bought. As a custom furniture builder, I appreciate how they allow for smaller boxes and lower shipping costs. Although the parts aren’t visible in the end, they look professional to the customer assembling it."

"Using these screw-in nuts has really elevated my woodworking skills. They provide a cleaner look for joints, avoiding unsightly nuts and overly long bolts. These are essential for creating movable parts and give space between joints, unlike traditional wood screws that pull everything tight."

"I appreciate that this set includes a drill bit, Allen key, and a case. There’s no need to worry about mismatched drill bits. I used it without any issues, and everything fits neatly back in the case for next time."

“I found these sturdy and well made. I had no issues, but I think the vendor should mention that they work well with fine threaded 8x32 screws.”

“These inserts are machined perfectly and easy to install. Just be cautious, as they can be sharp.”

“I used the inserts to attach 3/4 inch red oak slats to an outdoor bench. After some testing, I found that using a 7/16 drill bit made it much easier to insert straight. Even with the hardwood, they still had plenty of grip.”

"I found that threaded inserts work perfectly. Using a regular soldering iron with the special tool made it straightforward. Just remember to push straight in slowly to avoid any issues."

"I should have purchased these a long time ago! They really enhance the appearance of my 3D prints."

"I haven't tried them yet, but I'm excited to use them in my custom 3D printed boxes. I don't foresee any problems."

"I was very impressed with the quality and value of this large set. It truly surpasses the quality found in box stores. I do wish they offered a single Metric/SAE kit, but I can always purchase the Metric set separately if needed."

"While using these inserts, I noticed the lid was broken off when it arrived. The inserts themselves work great, even in high-stress situations. They are easy to use and durable, but having a damaged container isn't ideal."

"These are definitely better quality than those from big box home stores, and I appreciate the variety container. I used them to create an under-desk keyboard drawer for my wife, and they held securely to the MDF."

"As a hobby woodworker, I recently faced a challenge with a piece of furniture missing a threaded insert. I tried to resolve it with the seller but ended up getting nowhere. Instead, I found these inserts and thought, why not give them a shot? They arrived next day and took just a couple of minutes to install. They worked like a dream! I only needed one for my project, but I ordered a package of 60 since the price was unbeatable. They provide a much stronger joint than regular screws and can be removed without damage. I’m really happy with my purchase and plan to share them with my step-son, who also enjoys building things."

"I found these inserts to be quite effective! Although they aren't stainless steel, that wasn’t a concern for me as my project didn't require it. I used them on a butcher block workbench top, allowing me to remove and reattach it without damaging the holes. After some trial and error, I determined that a 3/8" drill bit worked best for installation. I also made a smaller pilot hole to prevent drifting, and everything went smoothly. I’d definitely recommend these for anyone looking to future-proof their projects!"

"For my garage, I created retainers using 1x4 PVC to keep the attic stairs tight against the weatherstripping. I utilized these 20mm inserts in combination with Powertec knobs, and they performed excellently, maintaining tension without any signs of pull-out after multiple uses. I initially considered the 15 mm inserts, but I opted for the 20 mm for added durability. Highly recommended for similar applications!"

"The price is great and the quality is impressive. These inserts seem to be made from high-quality brass, and the threads are spot on. I will definitely buy them again soon."

"I used these inserts for the first time and they are absolutely fantastic! The tapered end allows them to slide right in and they hold very securely. I'm planning to incorporate these into my building process from now on."

"I found the perfect M2 threaded inserts with a 3mm OD. They fit my needs exactly, and I would prefer to buy them in larger quantities than just 200. Measuring 2.9mm, they're ideal, but I'd also love if they were available in 6mm lengths!"

"I had never used these inserts before, but now, with my hobbies, I can't imagine working without them. Using my 3D Doodle pen to heat and push them in worked great. The packaging is well-organized, and I love that each compartment is clearly labeled. This style is definitely the right choice for me!"

"I do a lot of 3D printing and constantly need metric inserts in various sizes. The brass finish on these is impressive. I tested a few samples, and they held up well without stripping the threads. They heat up quickly and insert easily, holding firmly once cooled. I can't ask for much more!"

"These little inserts heat up quickly with my soldering iron and press in effortlessly. After cooling, they feel secure, and the screws work perfectly. The key is ensuring they are pressed in straight, which I'm still mastering. Overall, they work and look fantastic!"

"I found these inserts to be fantastic when making my kid's bed. I had no issues at all, as long as I drilled the right size pilot hole."

"For my oak workbench, I used these 1-inch steel threaded inserts with 25 of them for stability. They fit perfectly with no damage during installation, and I could even reuse some inserts without any problems."

"When installing locking swivel casters for my router table, I created an installation tool that made the process smooth. The inserts worked great, and I got a fantastic caster installation."

"I got these to repair a chair my wife received for free. I had to replace the wood support, and these inserts attached the legs back to the chair perfectly! Just remember to drill the right-sized holes for installation."

"I used these to fix a wooden table in our kitchen. The table had an MDF board glued to the bottom of a solid wood top. I drilled out the existing undersized inserts and stepped up to a 7/16" drill for the final hole size. The installation was straightforward, and they are holding up strongly. Very satisfied!"

"I bought these for a furniture leg from Ikea. They worked perfectly! It was a square leg, so I had to pay attention to orientation. I could either tighten or loosen the insert to ensure the leg was square. They’re inexpensive, and it was hard to find metric inserts like these locally. Delivery took less than a week!"
