Clean threads, consistent diameters, great selection of usefull sizes, and I really like the tapered end for starting them in the holes straight. Haven't had a single problem with them. Will definitely buy again. I recommend printing the holes to be a snug fit on the tapered tip and a small chamfer helps eliminate the squeeze out when they melt into the part. Review: Lots of possibilities! - I bought these for a 3d printing project I was doing, and have ended up using them for a few other projects as well. They're surprisingly easy to press into an object, and they hold well. I haven't had any issues with them getting pulled out. I also bought some tips for my soldering iron that fit these inserts, and that likely helped the process. These are great! ## Features - 【Various Sizes to choose from】This is a 145ps heat set inserts assortment kit which includeM3*3*4.2—20PCS,M3*4*4.5—20PCS,M3*5*4.5—20PCS,M3*5.7*4.6—30PCS,M4*6*6—15PS,M4*8.1*6.3—15PCS,M4*10*6—15PCS, M5*9.5*7—10PCS, total 8 sizes of M3 M4 and M5 to meet most of your needs. - 【Designed for 3D printing parts and other plastic parts】 These brass inserts are widely used in 3D printing and other plastic parts such as PLA,PETG,ABS,PPS,PP etc., they can firmly secure two different parts together and make it look professional. - 【Made of H62 Hard Brass】These brass threaded inserts are made of H62 High quality material, hard ,durable and corrosion-resisted at the same time ensures good thermal conductivity. - 【Precise and exquisite】These inserts are made under strict standards, precise and exquisite, the thread is smooth and clean, knurl is deep and the whole piece is polished and shiny - 【Easy to use】The bottom end of these inserts are tapered shape, so it is very easy to put it in place before inserting, once set in the heat set insert in the hole, then heating up your soldering iron at around 392℉（200 ℃）if it is PLA part,wait for a few seconds till the plastic flow around the insert then push it in vertically with a minimum force then it is done ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09MK4X1KQ | | Best Sellers Rank | #56,683 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #78 in Nut Inserts | | Brand | ShineNow | | Color | Gold | | Compatible Groove Diameter | 0.45 Centimeters | | Customer Reviews | 4.8 out of 5 stars 163 Reviews | | Drive Style | Spline | | Exterior Finish | Brass | | Fastener Type | Insert | | Finish Types | Polished | | Grade Rating | industrial | | Inside Thread Size | M3 | | Item Dimensions | 5.12 x 3.54 x 0.75 inches | | Item Weight | 110 Grams | | Manufacturer | ShineNow | | Material | Iron Brass | | Material Type | Iron Brass | | Metal Type | Brass | | Model | M3-M4-M5 | | Number Of Items | 145 | | Number of Pieces | 145 | | Part Number | M3-M4-M5 | | Screw Head Style | Flat | | Size Name | M3 M4 M5 Kit | | Thread Class | General Purpose | | Thread Size | M 5 | | Thread Style | Straight | | Thread Type | Threaded | | UPC | 784848330849 | ## Product Details - **Material:** Iron Brass - **Fastener Type:** Insert - **Thread Size:** M 5 - **Exterior Finish:** Brass - **Color:** Gold ## Images ![M3 M4 M5 Threaded Inserts for Plastic 3D Printing Heat Set Insert Kit 145pcs - Image 1](https://m.media-amazon.com/images/I/714VXkm+0fL.jpg) ![M3 M4 M5 Threaded Inserts for Plastic 3D Printing Heat Set Insert Kit 145pcs - Image 2](https://m.media-amazon.com/images/I/71TiUjtYBAL.jpg) ![M3 M4 M5 Threaded Inserts for Plastic 3D Printing Heat Set Insert Kit 145pcs - Image 3](https://m.media-amazon.com/images/I/61J8iDIvZML.jpg) ![M3 M4 M5 Threaded Inserts for Plastic 3D Printing Heat Set Insert Kit 145pcs - Image 4](https://m.media-amazon.com/images/I/61WM-f5TmqL.jpg) ![M3 M4 M5 Threaded Inserts for Plastic 3D Printing Heat Set Insert Kit 145pcs - Image 5](https://m.media-amazon.com/images/I/610DlBAIgHL.jpg) ## Available Options This product comes in different **Size, Number Of Items** options. ## Questions & Answers **Q: Does this kit provide details as to what size holes are recommended for each size of the inserts to fit into?** A: Unfortunately no it does not.
