Metallics TP520SFC – Frequently Asked Questions
1) What size and type of screw is the Metallics TP520SFC?
A #6 x 3/8 inch sheet metal screw with a flat head and a hex pin-in-head tamper resistant drive, made from 18-8 stainless steel. It ships as a 100 piece pack under part number TP520SFC.
2) Do I need a special bit to install the TP520SFC tamper resistant screws?
Yes. The head is a hex socket with a pin in the center, so a standard hex key or hex bit will not seat. You need a pin-in-hex (tamper resistant hex) driver bit sized to the #6 head. Order the driver with the screws if you don't already keep them on the truck.
3) Will 18-8 stainless screws hold up outdoors or in a damp location?
18-8 stainless is an austenitic chrome-nickel grade with good general corrosion resistance, so these #6 x 3/8 screws are suited to damp interior and typical exterior use. For coastal salt spray or chemical exposure, 316 stainless is the better choice.
4) Why use a tamper resistant screw on an electrical cover or enclosure instead of a standard one?
Pin-in-hex heads keep covers, device plates and enclosure panels from being opened with common tools, which is what you want in schools, transit areas, detention, public restrooms and multi-family common areas. The TP520SFC is the electrical-department version of that: a #6 x 3/8 sheet metal screw in stainless, so it serves security and corrosion at once.
5) Is the TP520SFC a flat head screw that will sit flush in a countersunk hole?
It is a flat head, which is the countersunk profile, so it seats flush when the hole is chamfered or the plate is dimpled for it. In a plain punched hole with no countersink the head will stand slightly proud.
6) How many Metallics TP520SFC screws come in a box?
100 pieces per pack. One part number, TP520SFC, no size or finish options to pick.
