E-z Lok DV-316-TH Brass Double Vane Threaded Insert 3/8-16

Product Description

The E-Z LOK DV-316-TH is a brass double vane tapered hole threaded insert designed to add durable 3/8-16 UNC inch threads to plastic substrates. The tapered hole design accommodates varying hole dimensions, with a small end hole diameter of 0.488 inches and a large end hole diameter of 0.540 inches. At 0.625 inches overall length with a 0.563 inch insert diameter and a 0.493 inch pilot diameter, this insert installs cleanly into pre-drilled tapered holes. The brass construction offers corrosion resistance and reliable thread engagement in a range of plastic parts. Minimum wall thickness requirement is 0.293 inches. Sold in packages of 25.

This insert is intended for use in plastic components where a strong, reusable threaded connection is required. The double vane design helps anchor the insert against rotation and pullout once seated. Typical applications include threaded repairs, OEM assembly, and field modifications on plastic housings and enclosures. It is well suited for production environments and service work where plastic threads are prone to stripping or where metal threads are specified for structural reasons.

Installation Notes

Installation is typically performed using a press or arbor to seat the insert flush with or below the surface of the plastic host material. Power down any assembly or fixture before installing inserts into live components. Verify that the pre-drilled hole matches the required taper dimensions before pressing to avoid cracking the surrounding material. Follow the host material manufacturer recommendations for minimum wall thickness and hole preparation.
