Metallics TP505SBC – Frequently Asked Questions
1) What size and type of screw is the Metallics TP505SBC?
The TP505SBC is a #8 x 3/4 inch sheet metal screw with a button head and a pin-in-hex tamper resistant drive, made from 18-8 stainless steel. It ships 100 pieces to the box.
2) Do I need a special bit to drive the TP505SBC tamper resistant screw?
Yes. The drive is a button head pin-in-hex, meaning there is a post in the center of the hex recess, so a standard hex key or hex bit will not seat. You need a pin-in-hex (hole hex) driver bit sized to the recess. Order the bit alongside the screws if you don't already carry one.
3) Will 18-8 stainless screws hold up outdoors or in a damp location?
18-8 stainless (the 300 series austenitic grade used on the TP505SBC) resists rust in wet and outdoor service far better than plated carbon steel, which is why it gets specified for exterior enclosures, pool and wash-down areas, and coastal jobs. For direct salt spray immersion, 316 is the step up.
4) Why use a tamper resistant screw instead of a standard Phillips sheet metal screw?
Pin-in-hex screws like the TP505SBC are used where the public can reach the hardware: panel covers, junction box covers, signage, restroom and transit fixtures, and anything in a school or correctional setting. The center pin blocks a common hex key, so a passer-by with a multi-tool cannot open the cover. If access control is not a concern, a standard Phillips sheet metal screw is cheaper and faster to drive.
5) Does the button head on the TP505SBC sit flush or stand proud of the surface?
Button head means a low domed head that bears on the surface, not a countersunk flush head. It needs no countersink or dimpled hole, but it does stand slightly above the panel face. If you need a flush finish, specify a flat head tamper resistant screw instead.
6) How many Metallics TP505SBC screws come in a box?
One hundred pieces per box. That quantity suits a property maintenance shop or an electrical contractor standardizing tamper resistant fasteners across a building's covers and plates, so one bit services every opening.
7) What is the manufacturer part number for this Metallics tamper resistant stainless screw?
Metallics part number TP505SBC. Call that out on a purchase order to get the #8 x 3/4 inch button head pin-in-hex 18-8 stainless sheet metal screw rather than one of the other lengths in the series.
8) Do I need to pre-drill for these sheet metal screws?
Sheet metal screws thread into a pilot hole rather than cutting their own in steel, so yes, drill a pilot sized for a #8 thread in the gauge you are fastening. In thin sheet you can often use an existing factory hole in the cover or plate.
