Metallics TP523SFC – Frequently Asked Questions
1) What size and head style is the Metallics TP523SFC screw?
It's a #8 x 1-1/4 inch flat head sheet metal screw with a hex pin tamper resistant drive. The flat head sits flush when the hole is countersunk, so it won't stand proud of a plate or cover you're fastening down.
2) Do I need a special bit to drive a hex pin tamper resistant screw?
Yes. The TP523SFC uses 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 (spanner-style hex) driver sized to the recess. Order the matching driver bit along with the screws if you don't already carry them, otherwise the fasteners cannot be installed or removed.
3) Why would I use a tamper resistant screw instead of a standard Phillips sheet metal screw?
Tamper resistant drives are used where the public can reach the hardware: panel covers, enclosure doors, restroom accessories, signage, transit and school fixtures. A Phillips or Torx screw comes out with any bit in a pocket; the pin-in-hex recess on the TP523SFC will not. If the fastener is in a locked room or above a ceiling, a standard sheet metal screw is cheaper and easier to service.
4) Will a #8 x 1-1/4 sheet metal screw hold in sheet metal and thin panel material?
Sheet metal screws cut their own thread in metal, so the #8 x 1-1/4 inch length is sized for sheet stock, boxes, covers, and thin panels where the screw can bite through and leave thread engagement. In sheet metal you want a pilot hole close to the screw's minor diameter, and in thicker plate the full 1-1/4 inch length gives you more thread to work with than a short pan head screw. It is not a wood screw and not a machine screw, so it should not be run into a tapped hole.
5) How many Metallics TP523SFC screws come in a pack?
They ship 100 pieces to the box under part number TP523SFC. That is a practical quantity for fitting out a run of enclosure covers or a set of fixtures in one trip, rather than a 10-count retail card. If you are standardizing tamper resistant hardware across a facility, order in multiples of 100 so every opening uses the same drive and the same driver bit.
6) Is the TP523SFC a single part number, or do I have to pick a size or finish?
One configuration only. TP523SFC is the whole order: #8 x 1-1/4 inch, flat head, hex pin tamper resistant sheet metal screw, 100 to the pack. There is no finish or length choice to specify, so distributors and procurement buyers can quote it straight off the part number.
