Metallics JDS183V – Frequently Asked Questions
1) Can a Type A sharp point tapping screw like this be used in sheet metal without pre-drilling?
Yes. The JDS183V is a Type A tapping screw with a gimlet (sharp) point, which pierces and taps its own thread in thin sheet metal, so light gauge work does not need a pilot hole. In heavier stock, pre-drill, because a Type A point is made for thin material. Threads are 12 per inch to ASME B18.6.4.
2) How many screws come in a jar of Metallics JDS183V and can I buy fewer?
They ship in jars of 500, and 500 count is the order minimum, so that is the smallest quantity you can take. One jar weighs 4.3 lbs.
3) Is the #10 x 1-1/4 inch indented hex head screw long enough for mounting through strut or a box flange?
The screw is #10 diameter by 1-1/4 inch long, which leaves usable thread after passing through a single sheet or flange. Subtract your material thickness plus the head height of 0.105 to 0.12 inch to work out the engagement you get. For a thicker stack-up, step up in length rather than relying on partial thread.
4) How much torque can these tapping screws take before they snap?
Minimum torsional strength is 48 lb-in, with case hardness of Rockwell C28-38 on AISI 1016-1024 steel. That is plenty for driving into sheet metal with a nut driver, but it means a high torque impact driver will twist heads off. Drive with a clutch set low and stop when the washer seats.
5) Do these Metallics tapping screws meet Buy American requirements for a government or institutional job?
They are flagged as both ARRA compliant and Buy American compliant, which is what a public agency or institutional procurement office usually needs to see on a fastener submittal. Country of origin is listed as multiple.
6) Are these zinc plated screws suitable for outdoor or damp locations?
The JDS183V is zinc plated carbon steel. Zinc handles indoor and dry protected work, which is where most electrical sheet metal and enclosure fastening happens. For wet, coastal, or corrosive exposure, specify stainless instead; plated steel will eventually rust in standing moisture.
7) What dimensional standard do these indented hex head slotted screws conform to?
Head dimensions follow ASME B18.6.3-2010 and the threads follow ASME B18.6.4. That matters if a spec sheet calls out a standard hex washer head tapping screw, since the head and washer geometry will match the submittal table. Note that #9 diameter sizes in the JDS family are independent of ASME B18.6.4.
8) I need a different length or diameter in this same hex head slotted tapping screw. Is that available?
Yes. The Metallics JDS series covers other diameters and lengths in the same indented hex head, slotted, sharp point configuration, and other pack quantities can be requested. Model JDS183V is specifically the #10 x 1-1/4 inch with a 5/16 head.
