Metallics JDS152V – Frequently Asked Questions
1) Will a 1/4 inch nut driver fit the Metallics JDS152V hex head tapping screw?
Yes. The JDS152V has an indented hex head measuring 0.244 to 0.250 inch across the flats, so a standard 1/4 inch nut driver or magnetic hex bit seats on it. Across corners it runs 0.272 inch. It also has a slotted drive, so you can back it out with a flat blade screwdriver when a driver will not reach, with a slot 0.045 to 0.054 inch wide and 0.052 to 0.066 inch deep.
2) Can I use the Metallics JDS152V sheet metal screw without drilling a pilot hole?
The JDS152V is a Type A tapping screw with a gimlet (sharp) point, which is the point style meant to start in thin sheet metal and form its own thread as it drives. In thin gauge stock it will self-start; in heavier material a pilot hole is still the right practice. Thread pitch is 15 threads per inch to ASME B18.6.4.
3) Is this #8 x 1/2 in. hex head screw strong enough to drive into steel studs or metal boxes without snapping?
Torsional strength on the JDS152V is rated 39 lb-in minimum, and the screw is heat treated to Rockwell C28-38 from AISI 1016-1024 carbon steel. That is the hardness range needed to cut thread in sheet steel without the point rolling over. Drive it with a clutch or a nut driver rather than full impact torque.
4) Are Metallics JDS152V tapping screws okay for a federally funded or Buy American job?
The JDS152V is flagged compliant for both ARRA and Buy American requirements. Country of origin is listed as multiple, so if your spec requires a single named origin on the submittal, that is the detail to pin down with the order.
5) Does the Metallics JDS152V have a built in washer under the head?
The head is an indented hex with an integral washer face, 0.322 to 0.348 inch outside diameter and 0.019 to 0.031 inch thick, with head height 0.096 to 0.110 inch. That bearing surface spreads load on thin sheet and spans a slightly oversized hole, so a separate washer usually is not needed.
6) Can zinc plated steel tapping screws like the JDS152V be used outdoors or in a wet location?
Finish on the JDS152V is zinc plating over carbon steel. Zinc plate is a mild indoor corrosion coating, so it suits dry interior work such as panel boxes, raceway, strut accessories and sheet metal enclosures. For exterior, damp or washdown locations, specify a stainless or hot dip galvanized fastener instead.
7) What dimensional standard do Metallics JDS indented hex head slotted screws meet?
Head and body dimensions follow ASME B18.6.3-2010, and the thread form follows ASME B18.6.4. Worth noting for anyone standardizing across sizes: dimensions for the #9 diameter in the JDS line fall outside ASME B18.6.4.
8) How much does a 500 count jar of #8 x 1/2 in. tapping screws weigh for shipping?
A jar of JDS152V screws comes in at 1.85 lbs, in a container measuring 3 x 3 x 3.6 inches. Light enough to carry several jars on the truck for service calls.
