Metallics DS1525M – Frequently Asked Questions

1) Is the Metallics DS1525M #8 x 1/2 in. tapping screw sold loose or only by the box?
The DS1525M ships as a box with a 5,000 piece minimum. That box weighs 15.94 lbs, so plan on a case quantity rather than a handful for a single device box.
2) Will a #8 x 1/2 in. Type A sharp point tapping screw bite into sheet metal without a pilot hole?
It is a Type A tapping screw with a gimlet (sharp) point and 15 threads per inch, so it starts itself in thin sheet metal, duct, and light gauge channel. Type A is a thread-forming screw, not a self-drilling one, so for heavier gauge steel you still want a pilot hole.
3) Do these Metallics screws qualify for a Buy American job?
The DS1525M is flagged Buy American compliant and ARRA compliant, which is what a government, school, or healthcare procurement file usually needs. Country of origin is listed as multiple.
4) What driver do I need for the Metallics indented hex head slotted screws?
Two options on the same screw: a 1/4 inch hex driver or socket across the flats (head width 0.244 to 0.25 in., 0.272 across corners), or a flat blade in the slot. The slot runs 0.045 to 0.054 in. wide and 0.052 to 0.066 in. deep, so a cabinet-tip screwdriver seats better than a wide blade. Hex is the faster drive in a tight panel.
5) Will the washer face on these hex head screws cover an oversized hole in a panel?
The integral washer under the indented hex head runs 0.322 to 0.348 in. outside diameter and 0.019 to 0.031 in. thick. That spreads the bearing surface wider than a plain #8 head, but it will not bridge a knockout or a badly oversized hole. For that, add a separate flat washer.
6) How much torque can a #8 Metallics tapping screw take before it snaps off in the hole?
Minimum torsional strength is 39 lb-in, with a case hardness of Rockwell C28-38. That is well inside the range of an impact driver, so dial the clutch back on a drill/driver. Snapping heads on a #8 is almost always over-torque, not a bad screw.
7) Are these zinc plated screws okay for outdoor or damp locations?
Material is zinc plated steel to AISI 1016-1024. Zinc plating handles dry interior and protected locations. For sustained wet exposure, coastal air, or direct ground contact, step up to stainless or a hot dip galvanized fastener instead.
8) What standards do the Metallics DS1525M screws meet, for a submittal package?
Head and body dimensions are to ASME B18.6.3-2010, threads to ASME B18.6.4, and the steel to AISI 1016-1024. Head height is 0.096 to 0.11 in. One note for the file: dimensions for the #9 diameter in this family fall outside ASME B18.6.4.
9) What are these #8 x 1/2 in. hex head tapping screws typically used for?
They are the standard mounting screw for electrical, plumbing, heating, and air conditioning work: device boxes and covers, duct and plenum sheet metal, strut and channel accessories, panel enclosures. The 1/2 inch length keeps the point from protruding far behind thin material.
10) Can I get the same Metallics screw in another diameter or length?
Yes. The DS1525M is the #8 x 1/2 in. configuration in the Metallics JDS indented hex head slotted tapping screw family, and other sizes and pack quantities are available on request.
