Metallics JTEKD32M – Frequently Asked Questions
1) Will the Metallics JTEKD32M meet a Buy American requirement on a federal job?
The JTEKD32M is flagged compliant for both ARRA and Buy American, though country of origin is listed as China. If your specification is written to a domestic-melt-and-manufacture standard rather than the ARRA/Buy American flags, confirm the origin against your contract language.
2) What standards does this #12 self-drilling tapping screw meet?
Threads are made to SAE J78 - 2013 and head dimensions to ASME B18.6.3-2010, with steel per AISI 1016 - 1024 and a case hardness of Rockwell C32-40. Minimum torsional strength is 92 lb-in. Note that SAE J78 does not cover #7 diameter drill screws, so a submittal calling for that size cannot be satisfied to this standard.
3) Does this Metallics screw come with a sealing washer or a plain washer?
It is an integral washer head, not a separate gasket. Washer outside diameter is 0.398 to 0.432 inches with a thickness of 0.022 to 0.039 inches, so it spreads bearing load over the panel but does not seal against water. For weather-exposed work you want a bonded EPDM washer screw instead.
4) How many screws come in a jar of Metallics JTEKD32M, and can I buy fewer?
These ship in jar packaging with an order minimum of 1,000 pieces. If you need a smaller count for a single install, this is not the pack to buy, it is a bulk quantity intended for repeat use.
5) Is a zinc plated self-drilling screw okay for outdoor or damp locations?
These are steel with a zinc finish, which is fine for dry interior work such as strut, panel enclosures, and metal framing. Zinc plating gives limited corrosion protection, so for exterior, coastal, or wash-down areas specify a stainless self-drilling screw instead. Metallics notes minimum torque values are the same for stainless and steel self-drill screws, so switching material does not cost you drive strength.
6) Is a 2 inch long #12 self-drilling screw too long for attaching to 14 gauge strut?
The JTEKD32M is a #12 diameter, 2 inch length screw with 14 threads per inch. Two inches is long for a simple metal-to-metal lap, where excess shank just protrudes behind the panel. Use this length when you are fastening through a thicker standoff, sleeper, or stacked assembly and still need to reach steel in the 0.110 to 0.210 inch range. For a direct panel-to-panel connection, a 3/4 or 1 inch #12 is the usual pick.
7) How much does a 1000-count jar of Metallics JTEKD32M screws weigh?
Product weight is listed at 17.1 lbs, in a container measuring 7.25 x 4.5 x 4.5 inches. Worth knowing if you are staging multiple jars on a cart or a lift.
