E-z Lok TH-124-SV Brass Single Vane Threaded Insert 10-24

Product Description

The E-Z LOK TH-124-SV is a brass single vane tapered hole threaded insert designed to install a durable 10-24 UNC internal thread into plastic assemblies. The tapered body allows the insert to be pressed or driven into a pre-drilled hole, with the single vane locking the insert against rotation once seated. Key dimensions include an insert diameter of 0.296 inches, a pilot diameter of 0.272 inches, and an overall length of 0.225 inches. Minimum wall thickness requirement is 0.159 inches, making it suitable for thin-wall plastic housings. This insert is specified in inch measurements and follows UNC thread standards. Maintenance technicians, assembly technicians, and field service pros working with plastic enclosures or components install this type of hardware.

This insert is intended for use in plastic substrates where a reliable machine-thread anchor is needed. The tapered hole design requires a drilled hole with a small end diameter of 0.267 inches and a large end diameter of 0.277 inches. It is well suited for light-duty fastening applications in plastic enclosures, control housings, and similar components found across HVAC, electrical, and general equipment assemblies where plastic panels or covers require threaded connections.

Installation Notes

Installation is typically performed by assembly technicians or field service personnel using a press or installation tool sized for the 0.296 inch insert diameter. Ensure the receiving hole in the plastic part is drilled to the correct tapered dimensions before driving the insert. Do not over-drive the insert, as this can crack thin-wall plastic housings. Verify the host material wall thickness meets the 0.159 inch minimum before selecting this insert for an application.
