Brass Heat-Set Threaded Inserts

Brass Heat-Set Threaded Inserts are the gold standard for assembling and securing plastic parts together. When installed, the serrated outer edges grab hold of the plastic that was locally melted around it and make for a reliable and repeatable threaded joint to screw into again and again. Available in the most common sizes for 3D-printed blaster builds (and a few uncommon sizes too). Organized by thread size and length.
