Metallics JFW138 – Frequently Asked Questions
1) How many screws come in a jar of Metallics JFW138 wood screws?
The JFW138 ships as a jar of 100 screws, and 100 count is the order minimum. Plan quantities in multiples of that jar rather than by the piece.
2) Will a #10 x 1-1/2 in. flat head wood screw sit flush in a countersunk hole?
Yes, that is what the flat head is for. The JFW138 head measures 0.34 to 0.385 inch across with a 0.116 inch head height, so a standard 82 degree countersink for a #10 flat head screw will bring it flush or slightly below the surface. If you are fastening a device bracket or plate with a punched countersink, check the opening is at least 0.385 inch to clear the largest head in tolerance.
3) Does the Metallics JFW138 meet a recognized dimensional standard for government or institutional specs?
Yes. The JFW138 is built to ASME B18.6.1, with threads to ASME B18.6.1-1997, so head, slot, and thread dimensions follow the published inch wood screw standard. It is also flagged ARRA compliant and Buy American compliant, which matters on federally funded work. Country of origin is China.
4) Do these Metallics wood screws need a pilot hole in hardwood?
The JFW138 has a tapered point and 13 threads per inch, which is a traditional wood screw thread rather than a self-drilling one. In softwood framing it will drive without a pilot; in hardwood, trim, or near an edge, drill a pilot so the slotted head does not cam out or the shank does not split the stock.
5) How far up the shank do the threads run on a 1-1/2 inch wood screw?
On lengths over 1 inch the thread covers roughly two thirds of the length, so a 1-1/2 inch JFW138 carries about 1 inch of thread with a plain shank under the head. That unthreaded shank is what lets the top board pull tight against the one beneath it when you are lagging a board or a mounting block in place.
6) Are zinc plated steel wood screws okay for outdoor or damp locations?
The JFW138 is steel with a zinc finish, which is a plating for general indoor and dry-location use. It gives some corrosion resistance but it is not a hot-dip galvanized or stainless screw. For exterior fastening, treated lumber, or wet locations, specify a stainless or hot-dip screw instead.
7) What is a #10 x 1-1/2 in. flat head wood screw typically used for on an electrical job?
This is the general purpose wood screw electricians and maintenance crews keep on the truck for mounting boxes, straps, clamps, and brackets to wood studs, blocking, and backboards. At 1-1/2 inches it reaches through a device bracket or strap and still gets solid bite into framing, and the flat head sits flush so nothing stands proud behind a cover plate or panel.
8) How much does a 100 count jar of these screws weigh for shipping or stocking?
A jar of 100 JFW138 screws comes in at 0.99 lbs, with the jar measuring 3 in by 3 in by 2.15 in. Useful if you are planning cart or van stock for a multi-jar MRO order.
