Metallics JRWS11V – Frequently Asked Questions
1) What size and length are the Metallics JRWS11V tapping screws?
They're a #8 diameter screw, 1-1/2 inches long, with a sharp point for driving into sheet metal, studs, and wood framing. The combination of that length and the #8 shank suits fastening through strap, box ears, or fixture flanges into framing rather than light sheet-to-sheet work.
2) Can I drive the JRWS11V screws with a square bit instead of Phillips?
Yes. The round washer head is a combo drive, so it takes either a Phillips bit or a square (Robertson) bit. Handy on overhead electrical work where a square bit holds the screw on the driver without a magnet.
3) Why pick a round washer head screw over a flat or pan head for mounting straps and boxes?
The round washer head gives a wider bearing surface than a pan head, so it won't pull through a strap hole, a thin box ear, or a slotted bracket. That's the reason it's the common choice for securing conduit straps, device boxes, and fixture hardware where the hole is larger than the screw shank.
4) Are the Metallics JRWS11V screws OK for outdoor or damp locations?
They're steel with a zinc plating, which handles indoor and normally dry locations fine and gives some protection in damp conditions. Zinc-plated steel is not a substitute for stainless in direct weather exposure, coastal air, or treated-lumber contact, so for those use a stainless fastener instead.
5) Do I need to pre-drill for these sharp point screws?
No pilot hole is needed in wood framing or thin sheet metal, the sharp point taps its own thread. They are not self-drilling, so for thicker steel, heavy angle iron, or masonry they're the wrong fastener. Masonry calls for a screw anchor instead.
6) What is the manufacturer part number for the Metallics #8 x 1-1/2 in. round washer head combo screw?
Order it as Metallics JRWS11V. That number covers the #8 by 1-1/2 inch round washer head combo drive sharp point tapping screw in zinc-plated steel, jar of 500. It's made in the USA.
7) How do the JRWS11V screws come packaged for a jobsite or truck stock?
They're supplied in a jar of 500, which is the format most electricians keep on the van or in a gang box, since it reseals and you can pour a handful into a pouch without a loose box spilling.
