Modeling an ISO-Accurate M6 Screw & Nut in Blender | Step-by-Step Hard Surface Tutorial

Hello fellow modelers! One of the most common situations you’ll face when stepping into the mechanical world is, without a doubt, dealing with bolts, screws, and nuts. Now, if you ever talk to a serious mechanic, be warned: they will pay extreme attention to terminology. So if you mention a bolt, they’ll immediately assume you’re referring to a specific screw tightened with a nut — and nothing else. And since I wouldn’t dare to test their patience, this tutorial does its best to stick to proper mechanical terminology and ISO standards. That said… if I still make any mistakes (and trust me, I probably will!), please be kind 😄 This is a step-by-step hard surface modeling tutorial where we model a mechanically accurate M6 screw and nut entirely in Blender, focusing on correct proportions, thread geometry, and clean topology. If you enjoyed the tutorial, feel free to leave a comment — and maybe subscribe, so you can join me on this humble (and very nerdy) journey ⚙️
