Metallics JDS182SS – Frequently Asked Questions
1) Can I use these 18-8 stainless screws on aluminum or steel without corrosion problems?
Watch it. Fastening 18-8 stainless parts to aluminum or steel can set up a galvanic couple in some environments, which corrodes the lesser metal around the fastener. Outdoors, in damp mechanical rooms, or in coastal air, that matters. Dry indoor electrical work is where these get used most, and the stainless resists rust where a plated carbon steel screw would bleed.
2) Are these screws Buy American or ARRA compliant for a public works job?
No. The Metallics JDS182SS 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 part will not satisfy them.
3) Do I need to drill a pilot hole for a #10 Type A sharp point tapping screw?
A Type A tapping screw with a gimlet (sharp) point is made to start in thin sheet metal and form its own thread, so a pilot hole is not always required in light gauge stock. In heavier sheet or when you want to avoid dimpling, a pilot sized for a #10 with 12 threads per inch keeps the thread from stripping. Type A is a sheet metal screw, not a thread cutting screw for thick plate.
4) Is the JDS182SS sold loose or do I have to buy a full pack?
These ship as a jar of 100, which is the order minimum on the Metallics JDS182SS. If you only need a handful for one panel, the jar is still the buying unit.
5) Does the JDS182SS have a built-in washer under the head?
Yes, the indented hex head carries an integral washer face with an outside diameter of 0.384 to 0.414 inch and a thickness of 0.019 to 0.031 inch. That gives a wider bearing surface than a plain hex head, which helps when you are pulling down on a sheet metal flange or a thin box wall and do not want the head to pull through.
6) What standards do these Metallics tapping screws meet for head and thread dimensions?
Head geometry on the JDS182SS follows ASME B18.6.3-2010 and the thread follows ASME B18.6.4. That means a submittal calling for a standard #10 Type A tapping screw will take this part. Note that dimensions for #9 diameter screws in this family are independent of ASME B18.6.4.
7) How hard is an 18-8 stainless tapping screw, and will it thread into steel studs or strut?
Hardness runs Rockwell C28-38. That is enough to form threads in light gauge sheet, but stainless tapping screws are softer than case hardened carbon steel self-drillers, so driving into heavy structural steel or thick strut risks twisting the head off. For light gauge sheet metal, boxes, and duct, the 1 inch length with 12 threads per inch does the job.
8) How much does a jar of 100 of these #10 x 1 inch stainless screws weigh?
A jar runs 1.15 lbs, with the container measuring 3 x 2.15 x 3 inches. Useful if you are kitting out service vans or counting weight on a shipment of multiple jars.
