Heat-Set Inserts for Thermoplastics

Zoro Select DV-316-TH-PK25 inserts are designed for heat installation into thermoplastic components. The brass construction provides corrosion resistance and reliable thread engagement. Each insert features a tapered shank with two vanes that resist pull-out and rotation under load. Suitable for repair, prototyping or low-volume assembly work.

Installation Limits and Hole Preparation

A drill bit of .488 in creates the pilot hole, while the maximum hole diameter is .54 in. Minimum material thickness is 19/64 in to ensure full engagement. The right-hand coarse thread follows a 3/8 in.-16 pattern. Heat-set installation requires controlled temperature to avoid degrading the surrounding plastic.

Brass Build and Flush Mounting

Plain-finish brass offers consistent thermal conductivity during installation. The flush flange sits level with the part surface for a clean profile. Tapered end diameter of .488 in aids alignment when pressing into the heated hole. Pack of 25 supports repeated use across multiple projects.
