Metallics TP226SFC – Frequently Asked Questions
1) Will a standard driver bit work on the TP226SFC, or do I need a special tamper-resistant tool?
You need a tamper-resistant bit. The TP226SFC uses a star pin (6-lobe with a center pin) drive, so a plain Torx bit will not seat, because the pin blocks it. The whole point of the head is that a standard bit set cannot remove it, which is why it gets used on public-facing covers, enclosures and panels. Order the matching pin-in-star bit in the size the screw takes before you go to the job.
2) Are these Metallics screws stainless, and can they be used outdoors or in damp locations?
They are 18-8 stainless steel, an austenitic grade with roughly 18 percent chromium and 8 percent nickel, so they hold up in wet and outdoor conditions far better than plated carbon steel. That makes the TP226SFC a reasonable choice for exterior enclosure covers, wash-down areas and coastal-adjacent work. For direct salt immersion a 316 grade would be the step up.
3) Is the TP226SFC a flat head screw that sits flush in a countersunk hole?
Yes, it is a flat head (FH), which means a conical underside that seats into a countersunk hole and finishes flush with the surface. If your plate or cover is punched with a straight, un-countersunk hole, a flat head will stand proud and clamp on the edge only, so you want a countersunk hole or a different head style for that case.
4) What part number do I order for the Metallics 10-24 x 3/8 pin-in-star tamper screw?
The manufacturer part number is TP226SFC from Metallics. That is the identifier to quote for the 10-24 x 3/8 flat head, star pin tamper-resistant, 18-8 stainless machine screw in a 100-piece pack. Distributors cross-referencing a line item should match on that MPN rather than on the description alone, since the Metallics tamper screw family runs through many thread and length combinations.
5) How many screws come in a pack of Metallics TP226SFC?
One pack of TP226SFC is 100 pieces. For an MRO or facilities crew standardizing on one tamper-resistant fastener across a building, a hundred-count box covers a lot of cover plates and enclosure lids from a single bin location, and keeps the matching pin-in-star bit relevant to every opening you service.
