Metallics JQK521 – Frequently Asked Questions
1) What size and drive is the Metallics JQK521 screw?
The JQK521 is a #10 x 1-1/4 inch screw with an indented hex washer head taking a 5/16 inch nut driver, and a combo head so it can also be run with a slotted or Phillips bit. That dual drive is handy overhead, where you can seat it with a 5/16 socket instead of fighting a bit.
2) Is the JQK521 a self-drilling screw or do I need to pre-drill?
The JQK521 is a #10 x 1-1/4 sheet metal type screw, not a self-drilling point, so into steel you want a pilot hole. Into wood framing or soft substrates it drives directly.
3) What do electricians use a #10 x 1-1/4 hex washer head screw for?
It is a general electrical mounting fastener: strut and clamp hardware, box and enclosure mounting, strapping EMT, hanging small devices to wood or light-gauge steel. The 5/16 hex washer head spreads the load and lets you run a whole run of them with a nut driver in a drill.
4) What part number do I order for the Metallics 10 x 1-1/4 hex washer head combo screw?
Order Metallics JQK521. That number covers the #10 x 1-1/4 indented hex washer head combo screw in the 100 count jar.
