Metallics JTRM80 6-32 x 1/2 in. Round Head Tri-Drive Machine Screws - Steel Zinc - Each

6-32 is the standard thread for electrical device plates, switches and receptacles, and the Metallics JTRM80 is a 6-32 x 1/2 inch machine screw in steel with a zinc finish. The 1/2 inch length is the common replacement length for standard wall plates and device mounting; longer screws are needed only when you are reaching through spacers or a deep-set box.

The head takes three drivers. It is a round head with a slotted, Phillips and square drive recess combined, so a flat blade, a Phillips bit, or a square (Robertson) bit all engage it. That is useful on service work where you are not carrying a full bit set.

Raised. It is a round head, meaning the top is domed and sits on the surface rather than countersinking flush. If you need the fastener to sit flush in a countersunk hole, a round head is the wrong choice and you want a flat head machine screw instead.

The JTRM80 is zinc plated steel, which is a mild corrosion coating meant for dry interior use. For wet locations, exterior enclosures or washdown areas, use a stainless steel machine screw instead, since zinc plating will eventually rust through in standing moisture.

They come in a jar, packed 100 to the jar. That is a shop or truck-stock pack rather than a bulk carton, which suits an electrician or maintenance tech keeping a count of common device screws on hand.

Yes, the JTRM80 6-32 x 1/2 inch tri-drive machine screw is made in the USA. That matters on public and institutional jobs carrying domestic-content requirements on materials.
