Metallics JDS154 – Frequently Asked Questions

1) What metal thickness will a #8 x 1 inch Type A tapping screw self-start in?
The Metallics JDS154 is made to self-start in thin metal from 0.015 to 0.050 inch thick, or in resin-filled plywood. Thicker steel needs a different screw type, since the gimlet point and the wide 15 threads per inch spacing rely on thin material to form their own thread.
2) Are Metallics JDS154 screws Buy American or ARRA compliant for a federal job?
No. The JDS154 is not Buy American compliant and is not ARRA compliant. Country of origin is listed as multiple. If your project carries domestic sourcing requirements, this screw will not satisfy them.
3) Can I drive the JDS154 with a nut driver, or do I need a screwdriver?
Either. The JDS154 has a combination hex and slotted drive, with an indented hex head measuring 0.244 to 0.25 inch across the flats and 0.272 across the corners, so a 1/4 inch nut driver seats on it. The slot runs 0.045 to 0.054 inch wide and 0.052 to 0.066 inch deep for a flat blade.
4) What is the difference between a Type A and a Type AB tapping screw?
A Type A screw like the JDS154 has wider spaced threads than a Type AB and a gimlet point. The coarse pitch (15 threads per inch at #8) grabs fast in very thin sheet, 0.015 to 0.050 inch. Type AB runs a finer pitch and is the better pick when you are going into heavier gauge or want more holding threads engaged in the same material depth.
5) Are these the screws for mounting electrical outlet boxes and sheet metal framing?
Yes. The JDS154 is specified for light metal assembly such as electrical outlets, framing and other sheet metal work. It is a #8 diameter, 1 inch long steel screw with a zinc finish.
6) How many screws come in a jar, and can I order a smaller quantity?
The JDS154 ships as a jar of 100, and 100 (one jar) is the order minimum. Other sizes and quantities are available by request.
7) Will these Metallics screws snap when driven with an impact driver?
The JDS154 is case hardened to Rockwell C28-38 with a minimum torsional strength of 39 lb-in. That is the failure torque to respect: a cordless impact can easily exceed it in thin sheet, so clutch down or use a driver with torque control. Material is AISI 1016-1024 steel.
8) Do these screws meet a published dimensional spec for submittals?
Yes. Head and drive dimensions on the JDS154 conform to ASME B18.6.3-2010, and the thread conforms to ASME B18.6.4. One caveat worth noting across the JDS line: dimensions for #9 diameter screws are independent of ASME B18.6.4.
9) Does the JDS154 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. That spreads the bearing load on thin sheet, so you generally do not need to add a separate washer. Head height is 0.096 to 0.11 inch.
10) Is a zinc plated steel tapping screw suitable for outdoor or damp locations?
The JDS154 is steel with a zinc finish, which is a dry-location coating. It is intended for interior light metal assembly such as outlet boxes, framing and sheet metal. For exterior or wet exposure, choose a stainless or coated exterior-rated fastener instead.
