Metallics TXV12200D – Frequently Asked Questions
1) What driver do I need for a 12-24 x 2 in. hex head drill screw?
A 5/16 hex driver or socket. The head measures 0.305 to 0.312 in. across the flats, 0.34 in. across corners, with a head height of 0.139 to 0.155 in. There is no Phillips or square recess, so the drive is hex only.
2) Can these drill screws be used outdoors or in a damp mechanical room?
Yes. The TXV12200D carries a zinc plus all-weather coating, which is what Metallics specifies for exposed and weather-contact steel-to-steel work. It is a coated carbon steel screw (AISI 1016-1024), not stainless, so for continuous salt spray or coastal immersion a stainless fastener is the better call.
3) Is there a sealing washer on the Metallics TXV12200D, or do I need to add one?
An integral washer is part of the head: outside diameter 0.398 to 0.432 in. with a thickness of 0.022 to 0.039 in. That spreads the clamp load on sheet steel. It is a metal washer face, not a bonded neoprene seal, so for watertight roof or wall penetrations you still need a separate sealing washer.
4) How tough are these screws, and will the head snap when I drive them into heavy steel?
Case hardness runs Rockwell C32-40 and torsional strength is 92 lb-in minimum, which is what lets the point drill steel without shearing. The usual failure in heavy steel-to-steel work is overdriving once the point breaks through, so back off the clutch as the washer seats.
5) Do these screws meet Buy American requirements on a federal job?
The TXV12200D is made in the United States, but Metallics lists it as not Buy American compliant and not ARRA compliant. If your contract carries a Buy American or ARRA clause, country of origin alone will not satisfy the submittal.
6) Is a 2 inch drill screw the right length for strut, angle iron and steel-to-steel hanging?
The 2 in. length gives you reach through standoffs, clips and stacked members, but the drill capacity is still 0.110 to 0.210 in. of actual steel. Length covers the gap; the panel thickness range governs what it can cut. For thin-gauge deck or light sheet only, a shorter screw with a smaller drill point wastes less drive time.
7) What thread does a 12-24 drill screw have, and will it hold in a tapped hole?
It is a 12-24 machine thread, 24 threads per inch, made to SAE J78 - 2013 with head dimensions to ASME B18.6.3-2010. Because it is a true 12-24 thread, it will also thread into an existing 12-24 tapped hole or nut, not just the hole its own point drills.
8) How are these Metallics TXV screws packaged and what is the smallest quantity I can buy?
They ship in a jar, with a minimum order of 50 each. Metallics notes other sizes and quantities of the Type BSD heavy duty drill screw are available by request.
