Metallics TP504SBC – Frequently Asked Questions
1) What size and type of screw is the Metallics TP504SBC?
The TP504SBC is a #8 x 1/2 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) What driver do I need for the pin-in hex head on these tamper resistant screws?
You need a pin-in hex (tamper resistant Allen) bit, not a standard hex key. The head has a center pin, so a solid hex driver will not seat. Size the bit to a #8 button head pin-hex screw and keep a couple in the van, since these are not a bit you will find in a general driver set.
3) Are these Metallics screws okay for outdoor or damp electrical enclosures?
They are 18-8 stainless, which is the common austenitic stainless used for corrosion resistance in wet and outdoor conditions, so they hold up far better than plain or zinc plated sheet metal screws on exterior enclosures, covers, and damp locations. For coastal salt spray, a 316 stainless fastener is the stronger choice.
4) Will a 1/2 inch long #8 sheet metal screw hold in sheet steel enclosure covers?
Yes, for sheet metal work that is what the 1/2 inch length is for. Sheet metal screw threads are coarse and cut their own hold in thin gauge steel, and 1/2 inch is enough engagement for cover plates, panels, and enclosure trim. If you are going through thick stock or need to pull up a gasket plus a cover, step up to a longer screw instead.
5) Why use tamper resistant screws instead of standard sheet metal screws on an electrical cover?
The point is deterrence in public or shared spaces. Pin-in hex heads cannot be removed with a screwdriver or ordinary Allen key, so panel covers, junction box lids, and device plates in corridors, schools, transit areas, and multi-family common areas stay closed to casual tampering. The tradeoff is that your own techs need the matching pin-hex bit on hand. For locked mechanical rooms, a standard screw is simpler.
6) Will a button head screw sit flush, or does it stand proud of the surface?
Button head means a low, rounded head that sits on top of the material, not flush. It needs a plain clearance hole rather than a countersink, and it leaves a small dome above the surface. If your panel is countersunk and you need the head flat with the face, you want a flat head tamper resistant screw instead of the TP504SBC.
7) How many Metallics TP504SBC screws come in a box?
One hundred pieces per box. That is a practical MRO quantity for standardizing tamper resistant covers across a floor or a building without buying a bulk carton.
