Metallics TP128SBC – Frequently Asked Questions
1) What kind of driver do I need for a button head hex pin screw like the TP128SBC?
You need a pin-in-hex (hex pin) tamper resistant bit sized for a 5/16-18 button head screw, not a standard hex key. The socket has a post in the center of the hex recess, so a plain Allen wrench will not seat. Order the matching pin-in-hex bit with the screws if your crew does not already carry one, otherwise the fasteners cannot be installed or removed.
2) Will a 1/2 inch long 5/16-18 screw be long enough for my cover plate?
At 1/2 inch of total screw length under the button head, the TP128SBC suits thin material, a sheet metal cover or a flange into a tapped boss, where you need only a few threads of engagement. If your cover plus the tapped part stacks up past about 1/2 inch you will run out of thread before the head seats, and you need a longer 5/16-18 hex pin screw instead. Measure the stack thickness plus the depth you want engaged in the tapped hole before you order.
3) What is the exact part number to order the Metallics 5/16-18 x 1/2 hex pin button head screw?
Order Metallics TP128SBC. That is the manufacturer part number for the 5/16-18 x 1/2 inch button head hex pin tamper resistant machine screw in the 100 piece pack, and it is the number to quote when matching screws already installed on a job so the heads and driver stay consistent.
4) How many screws come in a pack of Metallics TP128SBC?
Each pack is 100 pieces of the 5/16-18 x 1/2 inch button head hex pin screw, which is a bulk count rather than a contractor blister pack. For MRO stock or standardizing all the enclosure covers in a facility on one tamper resistant fastener, one box covers a lot of openings; for a single repair it is more screws than you need.
