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.

Questions about this item
Should I choose the 25-pack or a different quantity for my project?
The DV-316-TH-PK25 is supplied as a 25-piece pack of 3/8"-16 brass heat-set inserts, each 5/8 in long with a 9/16 in insert diameter.
What does the 3/8"-16 thread size mean when the insert is installed in plastic?
It provides a 3/8 in coarse right-hand thread in thermoplastic, requiring a 0.488 in drilled hole and at least 19/64 in material thickness for full engagement.
How does the heat-set installation process limit the maximum hole size?
The tapered shank and two vanes are designed for a 0.488 in drill bit; the maximum hole diameter is 0.54 in to ensure pull-out resistance in compatible thermoplastics.
