Metallics JTEKD11V 14 x 1-1/2 in. 3/8 Indented Hex Head Self-Drilling & Tapping Screws with Washer - #3 Drill Point - Steel Zinc - Each

It takes a 3/8 inch hex socket or nut setter. The head is an indented hex with a hex drive, measuring 0.367 to 0.375 inch across the flats and 0.409 inch across the corners, so a standard 3/8 inch magnetic nut setter in an impact or screw gun seats it cleanly.

No. The JTEKD11V is a Type BSD self-drilling and tapping screw with a #3 drill point, so it cuts its own hole and forms its own thread in one pass. Metallics cites a drill time of 2.5 seconds through a 1 mm thick plate. No pilot hole, no separate tapping step.

Metallics lists the JTEKD11V as both Buy American compliant and ARRA compliant. Country of origin is recorded as multiple, so if your contract requires a single named origin on the submittal, that is the detail to confirm with the mill cert rather than the catalog entry.

Three are published: dimensions to ASME B18.6.3-2010, threads to SAE J78-2013 (UNC form, 14 threads per inch), and steel to AISI 1016-1024 with a case hardness of Rockwell C32-40. Metallics notes that SAE J78 does not cover #7 diameter drill screws, which matters only if you are speccing that size.

The #3 point is the mid-range drill point in the self-drilling family, heavier than a #2 and used for thicker gauge steel rather than light sheet. For this 14 x 1-1/2 inch screw the published drilling reference is 2.5 seconds through a 1 mm plate. Combined total thickness of the materials you fasten plus the drill point length has to stay inside the 1-1/2 inch overall length, so plan your stack-up against that.

The washer is integral to the head, so nothing separate to buy. The washer face runs 0.480 to 0.520 inch outside diameter and 0.030 to 0.050 inch thick, which spreads the clamp load over a wider bearing area than a plain hex head gives you. Head height is 0.172 to 0.190 inch.

The JTEKD11V is carbon steel with a zinc plated finish, silver in appearance. Zinc plating is an indoor and sheltered-use coating; for sustained exterior exposure, salt air, or treated lumber contact, go to a stainless self-drilling screw instead. One note on torque if you are comparing the two: minimum torques are the same for stainless and steel self-drill screws, so the driver setup does not change.

No. The order minimum is 500 count, supplied in a jar. Metallics does note that other sizes and quantities are available by request, so a different length or diameter in a different pack is worth asking about, but 500 is the break on this item.

Metallics lists the packed jar at 8.75 lbs, measuring 7.25 by 6.25 by 6 inches. Useful if you are loading out a truck or working out shipping on a multi-jar order.
