Metallics JQK520V – Frequently Asked Questions
1) What size screw is the Metallics JQK520V, and what head and drive does it have?
The Metallics JQK520V is a #10 x 1/2 inch indented hex washer head screw with a 5/16 inch hex head, a combination drive (hex plus slot/Phillips so you can drive it with a 5/16 driver or a screwdriver), and a sharp point for self-starting into sheet metal. It ships 500 to a jar.
2) Do I need a drill bit or can I drive these self-tapping screws straight in?
The JQK520V has a sharp point rather than a drill point, so it self-starts in light gauge sheet steel, drywall and wood with no pilot hole. It is not a self-drilling screw: into heavier structural steel you will want a pilot hole or a drill point screw instead. The 5/16 inch hex head takes a standard 5/16 magnetic nut setter, and the combination drive gives you a screwdriver as a backup in tight spots.
3) Will a 1/2 inch sheet metal screw work for mounting device boxes and straps to metal studs?
Yes, that is the normal use for a #10 x 1/2 inch sharp point hex washer head screw like the JQK520V. The 1/2 inch length is sized for fastening into light gauge steel studs, box ears, straps and plates where you do not want the point protruding far behind the member. For thicker or doubled steel, or where you need more thread engagement, step up to a longer #10. These are sold as an electrical fastener.
4) What is the difference between an indented hex washer head screw and a pan head for electrical work?
The indented hex washer head on the JQK520V gives you a wide flange that bears on the material, which is what you want when you are clamping a strap, box ear or plate and do not want the head pulling through. It also drives from a 5/16 inch hex socket, so you can run them fast with a nut setter instead of fighting a cam-out. A pan head drives only from the slot or cross recess and has a smaller bearing surface. The combination drive here gives you both options on the same screw.
5) How many screws come in a jar of Metallics JQK520V?
500 screws per jar. The jar pack is what electricians and MRO stockrooms buy for a van or shop shelf, since the #10 x 1/2 hex washer head is a daily consumable on box and strap work rather than a one-job item.
