Metallics JDS182 – Frequently Asked Questions

1) Will a #10 Type A tapping screw hold in sheet metal without pre-drilling?
Type A tapping screws form their own mating threads in thin material, and the Metallics JDS182 uses a gimlet point to start cleanly in light gauge steel, aluminum, and galvanized stock. No tapped hole is needed, though a center-punch mark keeps the point from walking. At 12 threads per inch the coarse pitch is what gives it grip in thin material; it is a light metal assembly fastener, not a screw for heavy plate.
2) Can I use these #10 x 1 inch tapping screws for mounting outlet boxes and conduit straps?
That is the intended use. The JDS182 is specified for light metal assembly including electrical outlets, framing, and sheet metal work, which covers box mounting, panel and cover fastening, and conduit bracket attachment. Zinc plated steel gives it corrosion protection for interior electrical work.
3) Do Metallics Type A tapping screws meet ASME fastener standards?
Dimensions conform to ASME B18.6.3-2010 and the threads to ASME B18.6.4, with steel in the AISI 1016 to 1024 range. If a spec or submittal calls for a Type A tapping screw to those standards, this one is written to them. Note that it is not Buy American compliant and not ARRA compliant, with multiple countries of origin, so it will not clear a federally funded job with a domestic-sourcing requirement.
4) What size driver do I need for a Metallics indented hex head tapping screw?
A 5/16 inch hex driver or nut setter fits the indented hex head, and the head is also slotted so a flat blade works where a socket will not clear. The slot runs 0.05 to 0.06 inch wide and 0.057 to 0.072 inch deep, so a #2 cabinet tip seats properly; a wide blade will ride up. Head measures 0.305 to 0.312 inch across the flats with 0.34 inch across corners.
5) How much torque can a #10 Metallics tapping screw take before it snaps?
48 lb-in minimum torsional strength, with a Rockwell C28-38 case hardness. That is enough for driving with a screwgun or impact driver on light gauge material, but the number is the twist-off floor, not a target. Overdriving in thin sheet strips the formed threads before the screw breaks, so back the clutch off once the indented head seats.
6) What is the difference between an indented hex washer head and a plain hex head tapping screw?
The indented hex head on the JDS182 carries a washer face, 0.384 to 0.414 inch outside diameter and 0.019 to 0.031 inch thick, which spreads the clamp load over a wider footprint than a plain hex head. That matters in thin sheet, where a small bearing surface pulls through. Head height runs 0.105 to 0.12 inch, so it sits low enough not to foul a cover plate.
7) Should I use a Type A tapping screw or a self-drilling screw for attaching to metal studs?
Type A screws like the JDS182 need the point to pierce the material itself, so they suit thin gauge sheet, outlet boxes, and light framing. Heavier gauge stud or structural steel calls for a self-drilling point that cuts a hole before the threads engage, or a pre-drilled pilot. The gimlet point here starts easily but is a sharp point, not a drill point.
8) Will a 1 inch screw be long enough through a box and into a metal bracket?
One inch of length under the head leaves usable thread once you subtract the material being clamped, which is enough for a box flange or strap into light framing but tight if you are stacking a cover plus a bracket. Type A threads need a few threads of engagement past the far face to hold, so measure your total stack first and step up in length if it is over about half an inch.
9) How many screws come in a jar of Metallics JDS182?
100 screws per jar, and the jar is the minimum order unit. Weight of a full jar is 0.745 lbs. Buyers standardizing a truck stock or an MRO crib order in jar multiples rather than by the piece.
10) Are zinc plated tapping screws OK outdoors or in damp locations?
Zinc plating over steel is a corrosion resistant finish for interior and protected work, which is what the JDS182 is built for. Continuous wet exposure, coastal air, or contact with treated lumber will eventually take zinc plating down; stainless or a heavier coating is the call for those.
