Metallics JFW136 10 x 1 in. Flat Head Slotted Wood Screws - Steel Zinc - Each

The JFW136 ships as a jar of 100 screws, and 100 count is the order minimum, so that jar is the smallest unit you can take. Jar packaging keeps them together in a van or on a service cart rather than loose in a bin.

It depends on what you are going through. A 1 inch screw with about 2/3 in. of thread leaves limited penetration once you pass through a box ear or bracket, so it works where you are fastening directly to solid wood blocking or a stud face with minimal material in between. If you are going through drywall first or need deeper hold in framing, step up to a longer length in the same JFW wood screw family.

At 1 inch long, the JFW136 is threaded for roughly two thirds of its length at 13 threads per inch. Screws too short to carry the full minimum thread length run their threads as close to the underside of the head as practical. So on a 1 inch screw you get about 2/3 in. of thread biting the substrate, which is what sets your minimum usable material depth once you subtract the thickness of whatever you are fastening down.

The JFW136 is steel with a zinc finish. Zinc plating is a mild corrosion coating meant for dry interior service, electrical boxes, device plates, trim and wood blocking. For exterior exposure, pressure treated lumber or wet locations, go to stainless or a hot dip galvanized screw instead, since zinc plating will bleed rust in those conditions.

These have a tapered point, which is the traditional wood screw geometry, not a self-drilling or self-tapping tip. In softwood you can often drive them straight with a pilot in thin stock, but in hardwood or near an edge, pre-drill. A tapered point relies on the pilot to avoid splitting, unlike a type 17 auger point screw.

Yes. The JFW136 is built to ASME B18.6.1 for dimensions, with threads to ASME B18.6.1-1997. That is the wood screw standard a drawing or submittal normally calls out, so the head, slot and thread dimensions are interchangeable with any other screw built to the same spec in #10 x 1 in.

The JFW136 is flagged compliant for both ARRA and Buy American in the manufacturer data, with country of origin China. On a federally funded project, verify which clause your contract actually invokes, because Buy American provisions for fasteners are treated differently from job to job.

A jar runs 0.66 lbs and the packaged dimensions are 3 x 3 x 2.15 in., so it drops into a van drawer or a parts bin without taking a shelf. Useful if you are stocking a truck with several sizes at once.
