Metallics JTEKDHH6M – Frequently Asked Questions

1) What standard do these Metallics self-drilling screws meet, and are they Buy American compliant?
Threads are made to SAE J78 - 2013, and the steel is AISI 1016 to 1024 case hardened to Rockwell C32-40. Both Buy American and ARRA compliance are flagged on the JTEKDHH6M, which matters on federally funded work. Country of origin is listed as multiple.
2) How much bearing surface does the high hat washer head give, and will it pull through sheet metal?
The integral washer head has an outside diameter of 0.364 to 0.414 in., noticeably wider than the 0.305 to 0.312 in. hex, so the load spreads over more sheet than a plain hex head would. Head height is 0.125 to 0.13 in. That extra bearing area is the reason these get used for hanging and panel work where a bare hex head would dimple or pull through.
3) Will these screws snap if I drive them with an impact driver?
Torsional strength on the JTEKDHH6M is 61 lb-in minimum. That is the twisting load the screw takes before it shears, and an impact driver can exceed it easily once the head seats. Use a screw gun with a depth-sensing nose or a clutch, back off the torque setting on an impact, and stop driving as soon as the washer head beds down.
4) Can zinc plated self-drilling screws be used outdoors or in a damp mechanical room?
Finish is zinc plating over steel. That handles indoor and protected conditions, dry mechanical rooms, interior panel and duct work. For sustained exterior exposure, washdown areas, or anywhere near coastal air, zinc plating is not the right corrosion protection and you want a stainless or coated fastener instead.
5) Are these #10 screws fine thread or coarse, and what thread count?
16 threads per inch on the #10 diameter, which is the standard self-drilling thread pitch for metal-to-metal work under SAE J78. Thread length covers the 3/4 in. screw length.
6) How are the Metallics JTEKDHH6M screws packaged and what is the minimum order?
They ship in a jar of 1,000, and 1,000 is the order minimum, so this is bought by the jar rather than by the piece. Shipping weight on the jar is 6.5 lbs. Good buy for a shop that goes through drill screws; if you only need a handful, a jar is more than you will use.
