Metallics TXW14114 – Frequently Asked Questions
1) Does the TXW14114 screw come with the sealing washer already on it?
Yes, the bonded sealing washer is already assembled on the screw. The washer measures 0.480 to 0.520 in. outside diameter and 0.030 to 0.050 in. thick, and it compresses under the hex head to form a weather-tight seal at the fastener hole. Nothing separate to order or stack on.
2) Do these Metallics screws meet Buy American and ARRA requirements for a public project?
Yes. The TXW14114 is flagged Buy American compliant and ARRA compliant, with country of origin United States. That is the documentation a government, school, or healthcare procurement officer needs for a federally funded job.
3) What size driver or socket do I need for these 1/4-14 hex head screws?
A 5/16 in. hex driver. The head is a hex drive measuring 0.367 to 0.375 in. across the flats and 0.409 in. across the corners, which is the standard 5/16 socket. A magnetic nutsetter is the practical choice since the screw carries a bonded washer that has to seat square.
4) Can I use these on a roof or exterior wall panel, or will they rust out?
These are built for exposed work. The finish is zinc with an all-weather coating, and the bonded sealing washer seals the hole, which is why the screw is specified for applications needing a weather-tight seal. That combination is what distinguishes it from a plain zinc self-drilling screw used indoors.
5) How much torque will a 1/4-14 Metallics self-drilling screw take before it snaps?
Minimum torsional strength is 150 lb-in, with case hardness at Rockwell C32-40. That is enough to drill and tap through the rated 0.110 to 0.220 in. panel range without shearing, provided you run it at drilling speed and back off the gun once the washer seats. Over-driving crushes the sealing washer and breaks the seal before it breaks the screw.
6) What standards does the 1/4-14 Type BSD self-drilling screw conform to?
Dimensions follow ASME B18.6.3-2010, threads follow SAE J78-2013, and the steel is AISI 1016-1024. If your drawing calls out a Type BSD self-drilling screw to those standards, this is the item.
7) How many TXW14114 screws come in a pack and can I buy just a few?
They ship in a jar, with an order minimum of 100 count. There is no smaller break, so plan the count per opening or panel run before ordering. Metallics offers other sizes and quantities in the TXW series by request.
8) How much grip length do I actually get out of a 1-1/4 in. self-drilling screw with a washer?
The overall screw is 1-1/4 in. long and threads run 14 per inch. Subtract the #3 drill point and the drilled panel (0.110 to 0.220 in.) and you are left with the thread engagement into your substructure, so for thicker stacked assemblies step up in length rather than relying on this one. Head height adds 0.172 to 0.19 in. above the sealed surface.
