Metallics JTTS14 6 x 3/4 in. Pan Head Tri-Drive Tapping Screws - Steel Zinc - Each

The JTTS14 pan head takes three drivers: a flat blade in the slot, a Phillips bit, or a square drive bit. That is what tri-drive means here, so whatever is already on your belt or in the impact driver will seat it. Handy on service calls where you are not sure what the last tech used.

They are tapping screws, so they cut their own thread in a pilot or punched hole rather than needing a tapped hole. In sheet metal you still want a correctly sized pilot; in wood and softer stock the #6 thread will take hold directly. Note these are tapping screws, not self-drilling screws with a drill point, so they will not start their own hole in steel.

It is a #6 diameter screw with a 3/4 inch length. That size is the common one for mounting device boxes, straps, clamps, and small enclosures to wood or sheet metal, and the 3/4 inch length keeps it short enough that you are not punching through thin stock or a finished face.

They are steel with a zinc coating, which handles dry interior and generally damp interior work. Zinc plating is not a marine or sustained-wet finish, so for exterior exposure, coastal air, or anything washed down regularly, go to a stainless fastener instead.

A pan head sits on top of the surface with a broad flat bearing face, so it holds down a strap, clamp, or box flange without needing a countersink. A flat head wants a chamfered hole to sit flush. For sheet metal and device-box work where there is no countersink, the pan head on the JTTS14 is the right profile.

They ship in a jar, 100 screws per jar. The jar format is why they end up on a lot of service trucks and shop shelves, since it reseals and does not spill the way a bagged count does.

Yes, the JTTS14 tri-drive tapping screws are made in the USA, which matters on public and institutional jobs carrying domestic-sourcing requirements.
