Metallics JSTPO7 – Frequently Asked Questions
1) What size and type of screw is the Metallics JSTPO7?
The JSTPO7 is a #10 x 1-1/4 inch oval head Phillips sheet metal (tapping) screw in 18-8 stainless steel. The #10 diameter with a 1-1/4 inch length gives enough thread engagement for sheet metal, strap, and light bracket work while staying short enough for shallow backing.
2) Are the Metallics JSTPO7 screws stainless steel and OK for outdoor or damp locations?
They are 18-8 stainless steel, the austenitic grade commonly specified where plated carbon steel would rust. That makes the #10 x 1-1/4 tapping screw a reasonable pick for exterior strut, damp mechanical rooms, and coastal-adjacent work, though 18-8 is not the grade for direct salt immersion.
3) Why choose an oval head Phillips screw instead of a flat or pan head?
An oval head sits partly recessed in a countersunk or dimpled hole and leaves a low, rounded crown above the surface, so it is the choice when you want a finished look without the fully flush seat a flat head needs. A pan head sits entirely on top of the material. The JSTPO7 drives with a Phillips bit.
4) Do I need to drill a pilot hole for a #10 self-tapping sheet metal screw?
Tapping screws like the JSTPO7 cut their own thread but still need a clearance pilot in sheet metal and in any gauge that will not deflect. The oval head also wants a countersink or dimple if you want the crown to sit down rather than stand proud.
5) How are the Metallics JSTPO7 screws packaged for a service van?
They ship in a jar of 100. The jar format is what electricians and maintenance techs keep on the shelf or in a van bin, since it reseals and you can pour out a handful without losing the rest of the count.
6) Will stainless steel screws react with aluminum or dissimilar metal strut?
18-8 stainless fasteners in aluminum create a galvanic pair, and in wet or exterior locations that favors corrosion of the aluminum around the hole. For dry interior runs it is routine practice; outdoors, isolate the joint or stay with a matched-material fastener.
