Metallics JQK16WV – Frequently Asked Questions

1) Do I need to pre-drill for the Metallics JQK16WV self-piercing screw?
No pre-drilling. The JQK16WV is a sharp point self-piercing and tapping screw, so it pierces and forms its own thread in sheet metal as you drive it. Twin lead threads cut the driving torque, which is what keeps it from walking or stalling in thin gauge stock.
2) What driver do I need for these 1/4 hex head slotted screws?
Two options on the same screw. The head is a 1/4 inch hex, so a 1/4 inch hex driver or nutsetter in a drill runs them fastest. The head is also slotted, with a slot width of 0.045 to 0.054 in. and slot depth of 0.052 to 0.074 in., so a flat blade screwdriver works where you cannot get a driver onto the head.
3) What size and thread count is the Metallics JQK16WV screw?
It is a #8 diameter, 1-1/4 inch long screw at 15 threads per inch. That thread pitch and the undercut area beneath the head give a longer run of thread engagement than a straight shoulder tapping screw of the same length.
4) How much will the hex head and washer cover around the hole?
The hex head measures 0.244 to 0.25 in. across and 0.096 to 0.11 in. tall, with an integral washer outside diameter of 0.322 to 0.348 in. and washer thickness of 0.019 to 0.031 in. The washer bearing surface is what spreads load over a pierced hole in thin sheet, so plan on roughly a third of an inch of coverage, not more.
5) Are these screws hard enough to pierce steel studs and metal boxes?
The screw is case hardened to Rockwell C28-38 and made from AISI 1018 to 1022 steel. That is the normal hardness range for a self-piercing tapping screw working in sheet metal: hard enough to form its own thread in light gauge steel, not a concrete or hardened-substrate anchor.
6) Will zinc plated screws hold up outdoors or in a damp location?
The JQK16WV is zinc plated carbon steel. Zinc plating is an indoor and sheltered finish, fine for interior electrical work, boxes, duct and strut, but it is not a stainless or hot dip coating. For wet exterior or corrosive environments, specify a stainless or heavier coated fastener instead.
7) How are the JQK16WV screws packaged and what is the minimum order?
They ship in a jar, 500 count, and 500 is the order minimum. Jar weight is 3.1 lbs. Other sizes and quantities are available by request.
8) Do these Metallics screws meet Buy American and ARRA requirements for a public job?
The JQK16WV carries both an ARRA compliant and a Buy American compliant designation in the manufacturer data, with country of origin China. On a federally funded project, verify which standard your contract invokes, since ARRA compliance and domestic-origin Buy America clauses are not always the same test.
9) Can I use published head dimensions for self-piercing screws as an exact spec?
Treat them as a guide. Head dimensions on self-piercing screws differ from standard tapping screws, and there is no single governing standard for self-piercing screw dimensions, so the stated head, washer and slot ranges may deviate. If a drawing calls out a hard head dimension, check the actual screw against it before committing the whole run.
