This 1/4″-20×6.4 Short | Camera Thread heat set insert from CNC Kitchen is perfect for adding durable, reusable metal threads to your 3D printed parts. CNC Kitchen heat set inserts are made from high-quality, lead-free and cadmium-free brass, which are engineered specifically for embedding into thermoplastics like PLA, PETG, ABS, and other common filaments – giving you a safer, cleaner material to work with compared to lower-grade alloys.
The 1/4″-20×6.4 Short | Camera Thread is the universal standard for cameras, tripods, and photo and video accessories. This short 6.4mm version works best where the wall is thin or the part is compact. These heat set inserts are perfect for tripod adapters and plates, camera cages and rigs, cold shoe and accessory mounts plus much more!
The 1/4″-20×6.4 Short | Camera Thread heat set insert from CNC Kitchen is sold as a single unit. This allows you the freedom to order exactly how many heat set inserts you would like!
Each 1/4″-20×6.4 Short | Camera Thread heat set insert features a double-knurled outer surface for maximum resistance to pull-out and rotation forces once installed, plus a tapered pilot end that makes alignment and insertion quick and accurate. Simply heat the insert with a soldering iron (roughly 10–20 °C above your printing temperature) and press it into a pre-sized hole – it melts cleanly into the plastic and fuses in place as it cools, creating a strong, low-friction metal thread that can be screwed and unscrewed repeatedly without wearing out the surrounding material.
Compared to printing threads directly into plastic or repeatedly driving self-tapping screws, the 1/4″-20×6.4 Short | Camera Thread heat set insert gives you:
- High-quality brass – Premium-grade material that is lead-free and cadmium-free.
- Enhanced durability – Reinforced threaded holes that dramatically increase the strength and lifespan of the connection.
- Reliable assembly/disassembly – Parts can be screwed together and taken apart many times without wearing out.
- Professional finish – A clean and flush look for both DIY and commercial projects.
- Versatile installation – Melt into thermoplastics with a soldering iron or bond into resin prints with adhesive.
Whether you’re building enclosures, brackets, RC parts, or any project that needs a secure, reusable fastening point, CNC Kitchen heat set inserts deliver a professional-grade result every time.
