Metallics JSTPO1 Screw 6 x 2 OV PH TS 18-8 SS (Jar 100)

18-8 is the standard austenitic stainless grade (roughly 18% chromium, 8% nickel) and it is what gets specified when a plain or zinc plated steel screw would rust. That makes the JSTPO1 a reasonable choice for damp interiors, exterior trim, and coastal-adjacent work where carbon steel fasteners stain or seize. For continuous salt immersion, buyers typically step up to 316 instead.

An oval head seats into a countersunk hole like a flat head but leaves a low domed crown above the surface, so it reads as a finished fastener rather than a flush one. Electricians and trim installers use it where the screw stays visible, often with a finish washer. If you need the head fully flush with the material, use a flat head; if you are fastening to a flat unbored surface, a pan head is the better bearing shape. The JSTPO1 is the oval head Phillips version in #6 x 2 inch.

Order Metallics JSTPO1. That is the manufacturer part number for the #6 x 2 inch oval head Phillips 18-8 stainless screw supplied in a 100 count jar, and it is the only configuration under that number.

It is catalogued by Metallics as an electrical fastener, and a #6 x 2 inch stainless oval head Phillips is the length electricians reach for when a standard device screw is too short, such as reaching through thick wall buildup or fastening cover plates and straps into framing. The 2 inch length means you need adequate backing material behind the finish surface for the threads to bite.
