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. ## 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 | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 247,143 in DIY & Tools ( See Top 100 in DIY & Tools ) 315 in Nut Inserts | | Colour | Gold | | Customer Reviews | 4.8 4.8 out of 5 stars (152) | | Date First Available | 25 Nov. 2021 | | Finish | Polished | | Item Package Quantity | 1 | | Item Weight | 110 g | | Item model number | M3-M4-M5 | | Manufacturer | ShineNow | | Material | Brass | | Number of Pieces | 145 | | Part number | M3-M4-M5 | | Product Dimensions | 13 x 9 x 1.9 cm; 110 g | | Size | M3 M4 M5 Kit | ## Product Details - **Brand:** ShineNow - **Colour:** Gold - **Exterior finish:** Brass - **Fastener type:** Insert - **Finish type:** Polished - **Item dimensions L x W x H:** 13 x 9 x 1.9 centimetres - **Item weight:** 110 Grams - **Material:** Brass - **Metal type:** Brass - **Thread size:** M 5 ## 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) ## 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.

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 *by B***G on 11 November 2022* 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! ## Frequently Bought Together - ShineNow M3 M4 M5 Threaded Inserts for Plastic 3D Printing Heat Set Insert Kit 145pcs - HiLetgo 3pcs TP4056 Type-c USB 5V 1A 18650 Lithium Battery Charger Module Charging Board with Dual Protection Functions - HXJNLDC DC 3.7V 3000mAh 974058 Rechargeable Lithium Polymer Replacement Battery for DIY 3.7-5V Electronic Product, Mobile Energy Storage Power Supply --- ## 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.co.uk/products/396935236-m3-m4-m5-threaded-inserts-for-plastic-3d-printing-heat](https://www.desertcart.co.uk/products/396935236-m3-m4-m5-threaded-inserts-for-plastic-3d-printing-heat) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
