Metallics QK520M – Frequently Asked Questions
1) What part number do I order for Metallics 10 x 1/2 hex washer head combo screws?
Order Metallics QK520M. That number covers the #10 x 1/2 inch indented hex washer head combo drive screw in the 1000 piece box, and it is the only configuration under that number, so there is no length or head option to specify.
2) Can I drive the QK520M hex head screw with a nut driver instead of a bit?
Yes. The hex washer head takes a 5/16 inch nut driver or socket, which is how most electricians run these in a panel or on strut. The combo slot in the head gives you a bit option when the nut driver will not clear.
3) Is a 1/2 inch long #10 screw long enough for mounting electrical boxes and plates?
A 1/2 inch length is meant for thin-material fastening, sheet metal, box ears, covers, brackets, and strut accessories, where the screw only needs to pass through one or two layers of sheet. It is too short to anchor into framing lumber or through thick assemblies; for those use a longer fastener. The #10 diameter is the common size for electrical sheet metal work.
4) How many screws come in a box of Metallics QK520M?
One box holds 1000 pieces of the #10 x 1/2 inch hex washer head screw, which is the bulk count electrical contractors and MRO stockrooms buy for repeat panel, box, and bracket work rather than a small job pack.
