Metallics JTEKD9M – Frequently Asked Questions
1) Do I need to pre-drill for the Metallics JTEKD9M self-drilling screws?
No pilot hole needed. The JTEKD9M is a Type BSD self-drilling and tapping screw with a #3 drill point, so it drills its own hole and cuts its own thread in one pass through steel. Metallics notes drill time of about 2.5 seconds through a 1 mm thick plate.
2) Does the washer come attached to these screws or do I order it separately?
The washer is part of the screw, nothing to order separately. It measures 0.480 to 0.520 inch outside diameter and 0.030 to 0.050 inch thick, which spreads the clamp load on sheet metal and strut so the head does not pull through thin material.
3) What size driver or socket do I need for these 3/8 indented hex head screws?
A 3/8 inch hex socket or nut driver. The head is an indented hex measuring 0.367 to 0.375 inch across the flats, 0.409 inch across corners, with a head height of 0.172 to 0.19 inch. There is no slotted or Phillips option, the drive is hex only.
4) How are the Metallics JTEKD9M screws packaged and what is the minimum order?
They ship in a jar of 1,000 pieces, and 1,000 is the order minimum. Figure roughly 12.21 lbs for the packed jar.
5) Are these zinc self-drilling screws suitable for outdoor or damp locations?
The JTEKD9M is carbon steel with a zinc finish, silver in appearance. Zinc plating is a mild corrosion coating meant for dry interior and protected work, electrical strut, panel and sheet metal fastening. For sustained exterior exposure or wet locations, use a stainless self-drilling screw instead. Metallics notes that minimum torque values are the same for stainless and steel self-drill screws, so switching to stainless for corrosion resistance does not cost you driving performance.
6) Do these screws meet Buy American or ARRA requirements for a government job?
The JTEKD9M is flagged compliant for both ARRA and Buy American in Metallics' product data, with country of origin listed as multiple. On a federally funded project, pull the origin documentation for the specific lot you receive, since it is a multi-source item.
7) What standards do the Metallics JTEKD self-drilling screws are built to?
Dimensions follow ASME B18.6.3-2010 and the thread form follows SAE J78-2013, with UNC threads at 14 per inch. Worth knowing for spec work: SAE J78 does not cover #7 diameter drill screws, so if a drawing calls out a #7 you will not find a J78 reference for it.
