Metallics JTTS14M 6 x 3/4 in. Pan Head Tri-Drive Tapping Screws - Steel Zinc - Each

Three ways into the same head. The JTTS14M pan head is slotted, Phillips and square drive all in one recess, so a flat blade, a #1 or #2 Phillips, or a square bit will all seat it. That is handy on a service call where you only have one driver on the belt, and it keeps the crew from stripping heads swapping bits.

It is a #6 diameter by 3/4 inch long tapping screw. The 3/4 inch shank gives you enough thread to bite through sheet metal boxes, device plates, and light-gauge channel while still leaving the point short enough that it is not punching through finished surfaces behind. For anything thicker than the usual sheet-steel enclosure, step up in length.

Pan head is the general-purpose choice for electrical work: the flat underside bears on the surface and the slightly domed top sits proud, so it clamps straps, clips, ground wires and sheet-metal brackets without needing a countersink. If the hole in your part is countersunk or the head has to sit flush with the surface, you want a flat head screw instead, not this one.

The JTTS14M is zinc plated steel, which is a dry-interior finish. It handles normal indoor humidity fine, but in exterior, wet-location, or washdown work the plating will eventually give up and the screw will rust. For those openings, specify stainless steel fasteners instead.

These are tapping screws, so they cut their own thread in a pre-punched or drilled hole rather than forming it in solid stock. In sheet steel use the existing knockout or punched hole; in solid material drill a pilot sized for the #6 shank. They are not self-drilling, so they will not start their own hole in metal.

They ship in a jar of 1000 pieces. For a shop or facility crib that is a sensible bin item for a common #6 x 3/4 inch fastener, and the jar keeps them from spilling across a drawer the way a bag does.

Yes, the JTTS14M #6 x 3/4 inch tri-drive tapping screw is made in the USA, which matters on public and institutional jobs carrying a domestic-sourcing requirement.
