Metallics JTEK7PSS 10 x 1 in. Pan Head Phillips Self-Drilling & Tapping Screws - #2 Drill Point - 410 Stainless Steel - Each

The Metallics JTEK7PSS is rated for panel thickness of 0.035 to 0.110 inch, which covers roughly 20 gauge up through about 12 gauge sheet and light steel studs. The #2 drill point does the drilling, so no pilot hole is needed within that range. Thicker structural steel is outside what this point will handle.

One pass. It is a Type BSD self-drilling and tapping screw with a drill point, so it cuts its own hole and forms the thread as it drives. Drill time runs about 2.5 seconds through a 1 mm plate. Thread count is 16 per inch to SAE J78 - 2013.

Metallics lists the JTEK7PSS as both ARRA compliant and Buy American compliant, with country of origin recorded as multiple. That is the compliance flag procurement departments on government, healthcare, and education work are looking for on the submittal.

410 stainless is a hardenable martensitic grade, which is what lets the point drill its own hole. It gives better corrosion resistance than plain carbon steel for damp interiors and sheltered exterior work, but it is not 300-series stainless and will show surface staining in constant wet or coastal exposure. For salt or chemical exposure, specify a 300-series screw with a hardened carbon point instead.

A #2 Phillips bit. The recess diameter is 0.192 inch with a gaging depth of 0.089 to 0.113 inch, so a #2 seats fully and will not cam out at the rated torque. Keep the drill in low speed with steady pressure so the point cuts rather than work-hardens the panel.

Minimum torsional strength is 61 lb-in, with hardness at Rockwell C38-46. Set your impact or screwgun clutch below that figure. Metallics notes minimum torques are the same for stainless and steel self-drill screws, so there is no derate for choosing the 410 stainless version.

Head height runs 0.122 to 0.133 inch with a head width of 0.357 to 0.373 inch, built to ASME B18.6.3-2010. A pan head sits proud of the surface with a broad bearing face, so it clamps thin sheet well but needs that eighth inch of clearance. If the fastener has to finish flush, use a flat or wafer head instead.

At 1 inch of length with a #10 diameter and 16 threads per inch, there is enough shank to pass through a box flange or strut clip and still leave full thread engagement in sheet up to 0.110 inch thick. If you are stacking thicker brackets or shimming, step up to a longer length rather than counting on partial engagement.

They come in a jar, with an order minimum of 100 count. The packed jar measures 3 in length by 3 in width by 2.15 in height and weighs 0.72 lbs, so it drops into a service van bin or a stocked MRO shelf without repackaging. Other sizes and quantities are available by request.
