These M3 & M4 heat press insert tips are a fantastic option for 3D printing with thermoplastics. When the tip is heated and placed in the threaded brass inserts, the surrounding plastic softens and forms around it, creating a strong, secure bond. This keeps the insert firmly in place and strengthens the surrounding material, making the threaded connection more durable and resistant to pull-out compared to other insert types. Shaft outside diameter: 6.5mm Shaft inside hole diameter: 4.75mm Shaft inside hole depth: 25mm Shaft length to screw base: 28mm M3 tip length: 16.5mm M4 tip length: 17.5mm Assembled length w/M3 tip: 44.5mm Assembled length w/M4 tip: 45.5mm
