Metallics TXW1224112 – Frequently Asked Questions

1) Will the bonded washer on these 12-24 screws actually seal a metal roof or wall panel?
Yes. The TXW1224112 carries a bonded sealing washer with an outside diameter of 0.398 to 0.432 inch and a thickness of 0.022 to 0.039 inch, which compresses under the 5/16 hex head to make a weather-tight seal at the fastener hole. Set it just until the washer squeezes out flush; over-driving distorts the seal.
2) Do these Metallics screws qualify for a Buy American or federally funded job?
They do. The TXW1224112 is made in the United States and flagged compliant for both Buy American and ARRA requirements, which is what a government, school district, or healthcare procurement office needs on the submittal.
3) What driver or socket do I need for these hex head self-drilling screws?
A 5/16 hex driver. The head measures 0.305 to 0.312 inch across the flats and 0.34 inch across the corners, with a head height of 0.139 to 0.155 inch. Use a magnetic hex bit holder in a screw gun; the hex drive takes torque better than a Phillips in heavier gauge steel.
4) How tough are these screws, and will they snap in structural steel?
The TXW1224112 is case hardened to Rockwell C32-40 from AISI 1016-1024 carbon steel, with a minimum torsional strength of 92 lb-in. Keep the gun speed up and the pressure steady and stay within the 0.110 to 0.210 inch panel range; driving into steel heavier than that is where self-drillers twist off.
5) Are these screws rated for outdoor and exterior use?
Yes. The TXW series screw is finished in zinc with an all-weather coating, and the bonded sealing washer closes the hole against water. That is what makes it the common choice for exterior metal panel, flashing, and rooftop equipment attachment rather than a plain zinc self-driller.
6) Is a 1-1/2 inch length too long for attaching light gauge panel to purlins?
At 1-1/2 inch overall, the TXW1224112 leaves plenty of thread past a single 0.110 to 0.210 inch panel, so the point will protrude on the back side. That is fine on a purlin or structural member where you want full engagement, but if the back side is exposed or close to wiring, step down to a shorter TXW length rather than running this one.
7) How are these sold, and what is the smallest quantity I can buy?
The TXW1224112 ships in a jar with a 100 count minimum order, and the jar weighs 1.64 lbs. If you need a different length or a bulk count, Metallics offers other sizes and quantities in the TXW line by request.
