Metallics JFW130 6 x 1 in. Flat Head Slotted Wood Screws - Steel Zinc - Each

The JFW130 #6 x 1 inch wood screws ship 100 to a jar, and 100 count is the order minimum. If you need another size or a different count, Metallics offers other sizes and quantities by request.

At a 1 inch nominal length, roughly two thirds of the screw carries thread, at 18 threads per inch with a tapered point. That means about 2/3 inch of bite into the lower member, so plan your pilot depth accordingly. On the shorter screws in the series, where 2/3 would not meet minimum thread length, the thread runs as close to the underside of the head as practical.

Metallics lists the JFW130 as both Buy American compliant and ARRA compliant, with country of origin China. Government, school and healthcare procurement teams working to those clauses can cite that compliance coding when submitting the fastener on a federally funded project.

The JFW130 has a slotted drive, which does not self center on a bit the way Phillips or square drive does. A flat tip walks out of the slot under power, so these are usually set by hand or on a low-speed clutch driver with a flat bit matched to the slot. The slot runs 0.039 to 0.048 inch wide and 0.024 to 0.038 inch deep, so size the bit to the slot width rather than grabbing the biggest flat tip in the box. If you're driving hundreds of fasteners on a production install, a Phillips or square drive wood screw will cost you less time.

Yes, that is what the flat head is for. The JFW130 head measures 0.244 to 0.279 inch across with a head height of 0.083 inch, so in a properly countersunk hole the top of the head finishes level with the surface. Flat head screws need the countersink; drive one into a flat-drilled hole and the head will stand proud and can split thin stock.

It's built to ASME B18.6.1, with threads to ASME B18.6.1-1997. That is the governing standard for slotted wood screws, so head diameter, head height, slot geometry and thread pitch all fall in the published tolerance bands, which is what a submittal reviewer looks for when a drawing calls out a standard wood screw rather than a proprietary fastener.

The JFW130 is steel with a zinc finish, which is a plating for general indoor and dry service. It gives moderate corrosion resistance for interior trim, device mounting and millwork, but it is not a marine or sustained-wet finish. For exterior decking, treated lumber or anywhere that stays damp, move to a stainless or hot dip galvanized wood screw instead.

A jar comes in at 0.37 lbs. Useful if you are batching a stockroom order of several sizes and need to total freight weight.
