Metallics JTEKD18SS – Frequently Asked Questions

1) Will 410 stainless self-drilling screws rust outdoors or on a rooftop unit?
410 stainless is a hardenable martensitic grade, which is what lets a stainless screw drill its own hole at all. It resists corrosion far better than plain carbon steel but is less corrosion resistant than 300 series stainless, so for coastal salt spray or chemical exposure expect some surface staining over time. For typical exterior electrical and HVAC work it holds up.
2) What driver do I need for a 5/16 indented hex head screw?
A 5/16 hex driver or nutsetter in a drill or impact. Head width runs 0.305 to 0.312 in. with 0.34 across corners, and head height is 0.105 to 0.12 in. Keep the gun at moderate speed: drill time is about 2.5 seconds through a 1 mm plate, and torsional strength is 61 lb-in minimum, so overdriving will snap the screw rather than seat it.
3) Does this screw come with a washer built in, or do I add one?
The washer is integral to the head, so nothing extra to buy. Washer OD runs 0.384 to 0.414 in. with a thickness of 0.019 to 0.031 in., which spreads load over sheet metal and helps seat strap, clamp and bracket flanges without pulling through. If you need a sealing washer for weather, that is a bonded EPDM washer screw instead, which this is not.
4) Can I buy these screws in a smaller quantity than a full jar?
No. These Metallics #10 x 1-1/4 in. hex washer head drill screws ship as a jar with an order minimum of 100 count, weighing 0.91 lbs. If you need a different size or a different count, Metallics offers other sizes and quantities by request.
5) Do these screws qualify for a federally funded or Buy American job?
Yes on both counts for the JTEKD18SS drill screw: it is flagged ARRA compliant and Buy American compliant. Country of origin is listed as multiple, so if your specifier needs the origin documented per lot, request it against the specific shipment.
6) What are the thread specs on the Metallics 10 x 1-1/4 self-drilling screw?
It's a #10 diameter, 1-1/4 in. long Type BSD self-drilling and tapping screw with 16 threads per inch in UNC form. Threads conform to SAE J78 - 2013 and head dimensions to ASME B18.6.3-2010. Hardness is Rockwell C38-46, which is the case hardness that lets the point cut steel.
7) Is a stainless self-drilling screw weaker than a carbon steel one for the same job?
Not in drive torque. Minimum torques are the same for stainless and steel self-drilling screws, and this one lists 61 lb-in minimum torsional strength. The reason to pick the 410 stainless version is corrosion exposure, not holding power.
