Metallics JSTPO8 – Frequently Asked Questions
1) What size and type of screw is the Metallics JSTPO8?
The JSTPO8 is a #10 by 1-1/2 inch oval head Phillips sheet metal (tapping) screw in 18-8 stainless steel. It comes packed in a jar of 100.
2) Are the Metallics JSTPO8 screws stainless and suitable for damp or outdoor locations?
They're 18-8 stainless steel, which is the austenitic 300-series grade used where corrosion resistance matters, so they hold up in damp interior and general exterior work far better than plain or zinc-plated steel. For salt spray or coastal exposure, 316 stainless is the step up.
3) Will a #10 oval head Phillips screw sit flush, or does it stand proud of the surface?
An oval head is a countersunk head with a rounded crown. The tapered underside pulls into an 82 degree countersunk hole, but the domed top stays slightly above the surface, so it's the head to use with finish washers or where you want a visible rounded profile rather than a fully flush face. If you need dead flush, use a flat head instead.
4) Do I need to drill a pilot hole for these #10 sheet metal screws?
They're tapping screws, so they cut their own thread in a pilot hole but do not self-drill. In sheet metal, light-gauge framing, or wood trim you still want a pilot sized to the screw's root diameter. There's no drill point on these, so for unpunched steel you'd want a self-drilling fastener instead.
5) Is the Metallics JSTPO8 a machine screw or a sheet metal screw?
It's a sheet metal tapping screw, not a machine screw. The #10 size refers to the nominal diameter only, and the thread is a spaced tapping thread meant to form its own mating thread in the material, so it does not run into a #10-24 or #10-32 tapped hole or take a standard machine screw nut.
6) How many Metallics JSTPO8 screws come in a jar?
One hundred per jar. The jar pack is the handy size for a service van or a parts bin rather than a bulk box, so it suits maintenance and trim-out work where you're pulling a handful at a time.
7) Can stainless JSTPO8 screws be used against aluminum or galvanized material?
Yes, 18-8 stainless is commonly run into aluminum and galvanized steel. Keep in mind the galvanic couple: stainless is the noble metal, so in wet exposure the aluminum or zinc coating is the one that sacrifices. For continuously wet joints, isolate or use a sealing washer.
