With a longer shank for deeper access and a design that prevents damage to your prints, this set is a must-have for any serious maker. Compatible with popular soldering iron models, it offers a cost-effective solution without compromising on quality. ## Description Heat set inserts are a great way to improve connection strength between 3D printed parts. If you have tried to set heat-set inserts in your plastic or 3D printed part with your soldering iron, you may have had the frustration of pushing the insert in only to have it come right back out stuck to your soldering iron and ruining your part in the process. Most soldering iron tips can catch on the rim of the insert causing it to stick on the iron when you pull the iron out. If you use the "horizontal method" it's hard to know the insert is straight. Our insert tips have a vertical wall that solves that problem. The iron pulls right out after pressing the hot insert. Because the shoulder is square it's easier to know if the insert is square in the piece, something that's harder to control with a conical soldering tip. The shank is much longer (0.75") and narrower than what you get with insert tips (only 0.25" long), allowing you to set small inserts into corners of parts without melting the side of the part. This is especially useful if you're mounting a circuit board in a 3D printed box or doing a mounting that requires the insert to come close to the edge of the part. Compatibility with 1/4" ST Series Weller tips, insert and set screw style, and internal ceramic heating element units like let you use the iron you already own. These tips are 1.6" (40 mm) long with the tip portion about 0.75" (19mm). There is a 5/32" internal cavity for ceramic heaters. On Weller irons with ST Series tips, the 1/4" shank can be extended as far as the set screw will allow. On Hakko FX888D irons, the 0.75" is the reach with 1/4" clearance. Two tips included, one for #4-40 and M3 and the other for M5 inserts. ## Features - Heat-Set Insert Installation tip better than soldering iron tip,Longer shank than other tips allows you to reach deeper into 3D printed parts and tight corners to install heat-set inserts without touching your iron and melting the plastic - compatible with many 1/4" Weller ST series tip irons internal ceramic heaters of many Hakko models.These installation tips slide over the ceramic heating element of the Hakko irons, just like the soldering iron tip, while still fitting in the 1/4" chamber of ST Series tips Weller irons. - Installation tip works better than soldering iron tip since conical tips can catch on the insert and accidentally pull the insert out while melting the plastic and ruining the part. - Perfect for 3D printing parts,One tip works for #4-40 and M3 and the other tip works for M5 inserts for same price as a single tip from other vendors. More types of inserts and better reach than other installation tips. /M3 tip works - WHY CHOOSE IGREAT?IGREAT Is a professional manufacturer of welding accessories,Can give you a Excellent soldering experience.If you have any questions,please contact us. if you need any soldering iron, just contact us, we accept custom ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | IGREAT | | Part Number | ST-10 | | Item Weight | 1.13 ounces | | Package Dimensions | 5.12 x 4.17 x 0.47 inches | | Is Discontinued By Manufacturer | No | | Color | Yellow | | Material | Iron | | Extension Length | 7 Centimeters | | Batteries Included? | No | | Batteries Required? | No | ## Images ![4pcs Heat-Set Insert Installation tip for Weller ST Series Tips,Work For Connecting 3D Printed Parts - Image 1](https://m.media-amazon.com/images/I/51r-HUUDLUL.jpg) ![4pcs Heat-Set Insert Installation tip for Weller ST Series Tips,Work For Connecting 3D Printed Parts - Image 2](https://m.media-amazon.com/images/I/612nKM9ltRL.jpg) ![4pcs Heat-Set Insert Installation tip for Weller ST Series Tips,Work For Connecting 3D Printed Parts - Image 3](https://m.media-amazon.com/images/I/51FJe31k-ZL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Fits my Hakko 880 and works as described *by C***T on Reviewed in the United States on November 20, 2019* I do a lot of 3d printing and wanted to upgrade bolt connections. So I looked at the thread adapters and wondered how to get them inserted. I saw this and purchased it. They fit my Hakko 880 soldering station and work perfectly with the temperature I have it set for soldering. I put the thread insert on the plastic, position it, then press lightly on the top with these tips in the soldering iron and eventually (within 20-30 seconds) the insert starts sinking in the plastic. Just make sure to predrill the holes appropriately to allow for them the be inserted without too much of the hole being refilled by the plastic being pushed down upon. I usually use a drill bit the side of the insert barrel less the grips. I've inserted several dozen so far and have been happy with the purchase. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Bought for a Voron build. these worked perfectly, & better then the included one from kit! *by A***R on Reviewed in the United States on April 1, 2022* I have only used 2 of the products, but of the 2, both worked flawlessly & allowed to heatset into the plastic more efficient than the one that was supposed to be exact fit from a different kit. Recommended! ### ⭐⭐ 2.0 out of 5 stars 2mm wide, but for M2.5 inserts NOT for M2 inserts *by S***E on Reviewed in the United States on March 4, 2021* I bought these because I needed the M2 insert. Unfortunately, it's not made for M2 screws: the end bit is far too wide to fit inside the insert (it's 2mm wide, while M2 screws are at most 1.9mm across). Luckily it was brass and i have a dremel, so I wound up filing it down to fit. It's not great and sometimes gets stuck due to the rough surface, but I guess that's what I have to deal with.Incidentally, it DOES fit just fine for M2.5 inserts, so I'm guessing this is just a mislabeling / someone not reading specs correctly before throwing it up on Amazon. :\ --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/95438593-4pcs-heat-set-insert-installation-tip-for-weller-st-series](https://www.desertcart.pt/products/95438593-4pcs-heat-set-insert-installation-tip-for-weller-st-series) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-23*
