Brass Heat-Set Threaded Inserts are the gold standard for assembling and securing plastic parts together. When installed, the serrated outer edges grab the plastic locally melted around them, creating a reliable, repeatable threaded joint to screw into again and again. Available in a variety of the most common sizes for 3D-printed blaster builds (and a few uncommon sizes too). Organized by thread size and length. Having trouble finding what you’re looking for?
