Metallics JTSS10 – Frequently Asked Questions

1) What driver bit do I need for the Metallics JTSS10 square drive screws?
A #2 square (Robertson) bit. The JTSS10 is specified for driver size 2R, and the recess measures 0.112 in. across flats with a gaging depth of 0.060 to 0.075 in. A worn or undersized bit is the usual cause of cam-out on square drive, so keep a fresh #2 in the gun.
2) Is a Type A tapping screw right for sheet metal boxes and duct, or do I need a self-drilling screw?
Type A is for pre-punched or pre-drilled holes in thin sheet metal, not for drilling its own hole. The JTSS10 has a gimlet point, which is sharp and will start in a pilot hole in light gauge steel, but it has no cutting flute, so a thicker gauge needs a pilot or a self-drilling (Type TEK) screw instead. Metallics lists it for electrical, plumbing, and HVAC work, so panel boxes, straps, and light duct are its normal use.
3) Do these Metallics tapping screws meet Buy American requirements for a government job?
No. The JTSS10 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project carries a domestic-content clause, this is not the screw to submit.
4) What size and thread count is the Metallics JTSS10 tapping screw?
A #8 diameter, 1-1/4 in. long screw with 15 threads per inch. The coarse 15 TPI count is what gives it bite in sheet metal rather than in wood or a tapped hole.
5) How much does the pan head stand off the surface, and will it clear a cover plate?
The pan head on the JTSS10 is 0.306 to 0.322 in. across and 0.105 to 0.115 in. high, so it sits roughly an eighth of an inch above the surface. That is fine under a strap or bracket, but it is not a flush head, so a cover plate seating directly over the screw needs the clearance or you want a flat head instead.
6) How is the Metallics JTSS10 packaged and what is the minimum order?
It ships in a jar of 100, which is the order minimum. Jar weight is 0.66 lbs. Metallics notes other sizes and quantities are available by request.
7) Will these screws snap when I run them in with an impact driver?
Torsional strength is 39 lb-in minimum, with the steel hardened to Rockwell C28-38. That is a case-hardened tapping screw, not a structural fastener, so back the clutch off on an impact driver. Driving a #8 tapping screw past its seating point is what shears heads.
8) Are Metallics JTSS10 screws suitable for outdoor or damp locations?
The JTSS10 is zinc plated carbon steel (AISI 1016-1024). Zinc plating handles indoor and dry-location work and incidental moisture, but it is not stainless. For wet locations, coastal exposure, or direct weather, specify a stainless tapping screw instead.
9) What dimensional standards do these pan head square drive tapping screws conform to?
Head and recess dimensions follow ASME B18.6.3-2013, and the threads follow ASME B18.6.4. Worth noting for anyone standardizing a fastener bin: Metallics states that #9 diameter dimensions fall outside ASME B18.6.4, so the #8 JTSS10 is the on-standard choice in that range.
