Metallics JTSF60 Screws 14 x 1-1/4 Fh Ph SMA Zn (Jar 100)

The JTSF60 is a #14 by 1-1/4 inch sheet metal screw with a flat head and a Phillips drive, zinc plated. It ships 100 screws to a jar.

Yes, as long as the hole is countersunk or the material is soft enough for the head to seat. The JTSF60 has a flat (countersunk) head, so it pulls down into the hole rather than standing proud like a pan or hex washer head. If you need the head to bear on the surface of sheet metal without countersinking, choose a pan head or hex washer head screw instead.

Zinc plating is a mild corrosion coating meant for dry indoor use. For exterior, damp, or wash-down locations, step up to stainless or hot-dip galvanized fasteners. The JTSF60 is zinc plated sheet metal screw stock for interior electrical work.

With 1-1/4 inches of total length under the flat head, the JTSF60 gives you roughly an inch of thread engagement after passing through a typical strap or bracket. That is enough for sheet metal, studs, or blocking, but it is not a masonry fastener and it is too long for thin trim where the point would protrude.

In sheet metal and thin steel, yes. A sheet metal screw like the JTSF60 cuts its own thread but needs a pilot hole sized to the screw's root diameter; in thin gauge sheet a punched or drilled pilot keeps the head from spinning out the material. In wood or plastic anchors it can be driven directly.

100 screws per jar. The jar packaging is handy for a van or shop bin where a bulk box would spill, and it keeps the #14 x 1-1/4 size separated from the other lengths on the truck.
