Metallics JTEKD143 – Frequently Asked Questions

1) What thickness of steel can a #5 drill point self-drilling screw go through?
The Metallics JTEKD143 carries a #5 drill point, the heaviest of the standard self-drill points, so it is the one you reach for when the substructure is thick steel rather than light gauge. It is built to SAE J78 - 2013 for the thread and drill point and ASME B18.6.3-2010 for head dimensions, with a 150 lb-in minimum torsional strength and Rockwell C32-40 case hardness so the point survives drilling instead of burnishing. Metallics rates drill time at 2.5 seconds through a 1 mm plate.
2) What size driver or socket do I need for the Metallics JTEKD143 hex head screw?
It is a hex drive, indented hex head measuring 0.367 to 0.375 in. across the flats and 0.409 in. across the corners, which is the 3/8 in. hex a 1/4 in. diameter drill screw normally takes. A 3/8 in. magnetic nut setter in an impact or screw gun drives it. Head height runs 0.172 to 0.19 in.
3) Does the JTEKD143 screw come with a sealing washer or just a bonded steel washer?
The washer on the JTEKD143 is an integral part of the head, 0.480 to 0.520 in. outside diameter and 0.030 to 0.050 in. thick. It is steel with a zinc finish, same as the screw, so it spreads bearing load under the head. There is no rubber or EPDM gasket in the spec, so for a weather seal on exterior panel work you would add a separate bonded washer or sealant.
4) Is a zinc plated steel self-drilling screw okay for outdoor or wet locations?
Zinc plated carbon steel to AISI 1016 - 1024 is a dry interior finish. It handles normal indoor industrial and electrical work, strut, hangers, panel and deck attachment inside a building, but sustained moisture, washdown, coastal exposure or contact with dissimilar metals will take the plating down. For those, use a stainless self-drilling screw instead.
5) How many Metallics JTEKD143 screws come in a pack and can I buy just a few?
The JTEKD143 ships in a jar with a 100-count minimum, so 100 pieces is the smallest quantity. Metallics notes other sizes and quantities are available by request. Shipping weight of the jar is 3.41 lbs.
6) Can I use the Metallics JTEKD143 on a federally funded or Buy American job?
The JTEKD143 is flagged compliant for both ARRA and Buy American in the Metallics data, while country of origin is listed as China. If your specification requires domestic melt and manufacture rather than the broader compliance flag, confirm which standard the spec section is calling for before you submit it.
7) Will a stainless self-drilling screw hold more torque than this zinc plated one?
No. Metallics states minimum torques are the same for stainless and steel self-drill screws, and the JTEKD143 is rated at 150 lb-in minimum torsional strength. Choose between the two on corrosion exposure, not on driving strength.
