Upgrade Weak Plastic Threads to Professional Strength
Plastic threads stripping? Screws loosening over time? HirtuOtter's brass heat-set inserts solve these frustrations with industrial-grade reliability.
Why Our Inserts Stand Out
Durable Brass Build: Resists wear and corrosion, outperforming cheap steel or aluminum alternatives.
Bidirectional Knurling: Angled serrations bite deep into melted plastic, creating a grip 2x stronger than smooth inserts.
Portable & Organized: Includes a reusable storage case to prevent loss—perfect for workshops, makerspaces, or on-the-go repairs.
Real-World Uses
3D Printing: Reinforce enclosures, Voron printer parts, or robotics joints.
DIY Fixes: Repair stripped threads in drones, RC cars, or household gadgets.
Professional Projects: Securely mount cameras, stage lights, or CNC clamps with imperial-standard sizing.
