M3×3mm Threaded Inserts Brass Heat Insert 100pcs

The brass threaded inserts M3 × 3 × 4.6 mm (Short) are compact embedment nuts for use in 3D-printed components with low wall thickness or shallow holes. The short height of 3 mm with an outer diameter of 4.6 mm makes this variant particularly suitable for applications where little installation depth is available. The knurled outer surface anchors itself into the plasticized plastic when embedding and reliably withstands both pull-out forces and torques.

Recommended accessories:

• C245 Soldering Iron Embedding Aid Threaded Inserts Insert M2-M8
• Soldering Iron Embedding Aid Threaded Inserts Insert M2-M8
• Threaded Insert Press Kit with Soldering Iron and Accessories
• Threaded Insert Press Kit Pro with Soldering Iron and Accessories

Features:

• Short height of 3 mm allows for use in thin-walled printed parts and shallow holes where standard inserts would not fit
• Brass material with high thermal conductivity enables fast, even embedding into all common FDM thermoplastics
• Knurled outer surface anchors itself form-fittingly into the solidifying plastic and reliably withstands pull-out and torque loads
• Assembly with conventional soldering station or embedding press – no threading or reworking required
• Compatible with M3 screws (ISO-Metric), suitable for PLA, PETG, ABS, ASA, PC, and other thermoplastics
• 100 pieces per package for serial applications, prototyping, and repair work

Application examples:

• Thin-walled 3D-printed housings and covers with little available installation depth for M3 screws
• Electronics projects with flat mounts and circuit board attachments with M3 threads
• Repair of plastic parts with damaged M3 threads and low available material strength
• Prototyping where compact height of threaded inserts is structurally specified
