Metallics JTEKS5 Screw 10 x 1/2 PN SD-PH TS D-Pt2 St- (Jar 100)

The JTEKS5 is a #10 x 1/2 inch self-drilling screw with a pan head and a Phillips drive. The drill point means it cuts its own pilot in sheet metal as you drive it, so no pre-drilling on light-gauge steel such as studs, strut, raceway, and enclosure walls.

For single-thickness light-gauge steel, yes. A 1/2 inch length on a #10 self-driller leaves enough thread past a sheet metal stud flange or an enclosure wall to hold, but it will not reach through stacked layers, through drywall into steel, or into wood framing. For those, step up to a longer self-driller in the same #10 size.

They ship 100 to a jar. The jar pack is what electricians keep on the van or in the gang box for daily sheet metal work, rather than a bulk carton.

The JTEKS5 carries a drill point, so it bores its own hole in steel before the threads engage. A self-piercing or sharp-point sheet metal screw has no cutting flute and needs either very thin material or a pre-punched hole. If you are fastening to steel studs, strut, or metal enclosures, the drill-point version is the one that goes in without a second step.

They are steel. That suits dry interior electrical work, boxes, straps, raceway, and panel mounting. For exterior or damp locations, specify a stainless or heavily coated self-driller instead, since plain steel will corrode in weather.

A Phillips bit. The head is a pan head with a Phillips recess, so a standard #2 Phillips in a drill or impact driver seats it. Pan heads sit low and broad, which is what you want under a strap, clamp, or box ear where a hex washer head would hold the part off the surface.

Order it as Metallics JTEKS5. That number covers the #10 x 1/2 inch pan head Phillips drill-point steel screw in the 100 count jar, with no further options to specify.
