Metallics JDS152M – Frequently Asked Questions

1) What size pilot hole do I drill for a #8 Type A tapping screw?
A #2 drill point size is specified for the JDS152M. In thin sheet under .050 inch you can often start the gimlet point in a punched or knockout hole without pre-drilling at all; in heavier stock, drill the pilot so the threads cut rather than wedge.
2) Are these screws suitable for a Buy American or ARRA funded project?
The JDS152M is flagged compliant for both ARRA and Buy American. Country of origin is listed as multiple, so if your contract requires documented origin on a specific lot, get that confirmed against the shipment.
3) Can I drive these hex head screws with a nut driver, or do I need a screwdriver?
Either works. The JDS152M has a combination drive: a 1/4 inch indented hex head measuring 0.244 to 0.25 inch across the flats, 0.272 across the corners, so a 1/4 inch nut driver or magnetic hex bit seats on it. It also carries a slot 0.045 to 0.054 inch wide and 0.052 to 0.066 inch deep for a flat blade when you cannot get a driver square to the work.
4) Do these Metallics tapping screws have a built-in washer face, or do I need to add washers?
No separate washer needed. The indented hex head includes an integral washer face with a 0.322 to 0.348 inch outside diameter and a thickness of 0.019 to 0.031 inch, which spreads the clamp load over sheet metal and knockout holes. Head height runs 0.096 to 0.11 inch.
5) How many screws come in a pack of Metallics JDS152M, and can I buy a smaller quantity?
The JDS152M ships in a jar of 1,000 pieces, which is also the order minimum. Other sizes and quantities in the line are available by request. The packed jar weighs 3.11 lbs.
6) Will these screws snap when I run them in with an impact or drill driver?
Torsional strength on the JDS152M is 39 lb-in minimum, with the steel case hardened to Rockwell C28-38 and made from AISI 1016-1024 steel. That is adequate for driving into light-gauge metal with a standard drill driver at moderate speed. High-torque impact drivers on a #8 screw this short are the usual cause of twisted-off heads, so back the torque down.
7) What standards do these indented hex head tapping screws conform to?
Dimensions follow ASME B18.6.3-2010 and the threads follow ASME B18.6.4, with UNC thread form at 15 TPI. One caveat worth knowing if you are specifying across diameters: dimensions for the #9 diameter in this line are independent of ASME B18.6.4.
8) Is a zinc plated steel tapping screw okay outdoors or in a damp mechanical room?
Zinc plating on steel is a dry-location finish. The JDS152M is steel with a zinc finish and a silver head, which handles interior electrical work, panel and enclosure assembly, and conditioned mechanical spaces. For exterior exposure, wet locations, or anywhere in contact with treated lumber, specify stainless or a coated exterior fastener instead.
