I fly Remote Controlled airplanes and most are made overseas and thus are metric. I now have ordered similiar boxes of screws in 2mm, 3mm and this one of 4mm. These sizes are hard to find in a hardware store and if found, the cost of gas getting there and the price of the screw, to say nothing of your time, makes buying boxes of various sizes a great deal. ## Frequently Bought Together - Kadrick Metric Screws Assortment,1400 Pcs M4 Screws Nuts Washers Assortment M4x6MM-40MM, Hex Socket Button & Cap Head M4 Machine Bolts Kit, 12.9 & 10.9 Grade Black Alloy Steel for 3D Printing - Kadrick 420Pcs M3 M4 M5 Threaded Inserts Assortment Kit for 3D Printing Components, Metric Brass Knurled Nuts, Insert by Heat into Plastic Parts - Heat Set Insert Tool,Tips for Threaded inserts M2 M2.5 M3 M4 M5 M6, Soldering Iron Tips for 3D Printer Users,Compatible with 900M/T18/FX-888D Irons- Press Tool for Plastic 3D Printer Components --- ## 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.ro/products/628669261-1580pcs-m4-hex-socket-cap-head-and-button-head-screws](https://www.desertcart.ro/products/628669261-1580pcs-m4-hex-socket-cap-head-and-button-head-screws) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-09-17*
