Metallics JDS86 – Frequently Asked Questions
1) What is a Type A tapping screw and what material should I be driving the Metallics JDS86 into?
Type A is a sharp gimlet point thread-forming screw. It cuts its own thread as it goes, so it is driven into sheet metal, thin steel, and wood-type substrates without a tapped hole. The JDS86 is a #12 diameter, 2-1/2 inch long screw with 11 threads per inch, so the coarse thread and long shank suit anchoring into framing, strut, or sheet metal hangers rather than into thick structural steel plate.
2) Will these screws snap if I run them in with an impact driver?
The JDS86 is heat treated to Rockwell C28-38 with a minimum torsional strength of 83 lb-in. That is the published breaking torque, so set an impact or clutch driver below it. The material is AISI 1016 to 1024 steel. Running a high-torque impact flat out into dense substrate is the usual cause of twisted-off heads on a #12 tapping screw.
3) Are the Metallics JDS86 screws OK for a Buy American or ARRA funded job?
Both the ARRA and Buy American fields on the JDS86 are flagged compliant. Country of origin is listed as multiple, so if your specification requires a single named origin on the submittal, have that confirmed for the lot you receive before you install.
4) Does the Metallics JDS86 tapping screw come with an integral washer under the head?
Yes. The indented hex head carries a washer face measuring 0.398 to 0.432 inch outside diameter and 0.022 to 0.039 inch thick. That spreads the bearing load over sheet metal and keeps the head from pulling through thin gauge material, so you do not need to stack a separate flat washer for most hanger and box work.
5) How thick a stack can a 2-1/2 inch tapping screw actually hold together?
At 2-1/2 inches overall length, the JDS86 gives you the full shank minus head to work with, and a Type A gimlet point needs several threads of engagement past the stack to hold. Practically, that means a fastened thickness well under 2 inches if you want solid thread engagement in the base material. For thin sheet-to-sheet work the 2-1/2 inch length is longer than needed, and a shorter screw in the same series is the better call.
6) How do the JDS86 screws ship and is there a minimum order quantity?
They ship as a jar of 100, which is also the order minimum (100 count). The packed jar weighs 2.05 lbs. Metallics lists other sizes and quantities in this family on request if a #12 by 2-1/2 inch is not the length you need.
