Metallics JTTS31 10 x 2 in. Pan Head Tri-Drive Tapping Screws - Steel Zinc - Each

The JTTS31 pan head takes three drive types in the same recess: slotted, Phillips, and square. That means a flat blade, a Phillips bit, or a square (Robertson) bit will all drive it, so you can run whatever is already in the drill or screwdriver pouch without swapping tips between tasks.

These are zinc plated steel. The plating handles indoor and normally dry conditions and incidental moisture, but it is not a stainless or hot dip galvanized fastener, so for persistent wet exposure, coastal air, or treated lumber contact, pick a stainless or galvanized screw instead.

A pan head sits on top of the surface with a broad flat bearing face and a rounded crown, so it clamps straps, clips, and box ears without needing a countersink. A flat head requires a chamfered hole to seat flush; a truss head spreads wider for oversized or slotted holes. For device boxes, conduit straps, and panel mounting, the pan head on the JTTS31 is the usual choice.

It is a tapping screw, so it cuts its own thread in the material as it drives. In sheet metal and light steel you still want a pilot hole sized to the screw's root so the threads form cleanly rather than stripping or spinning the workpiece; in wood it will drive without one. Tri-drive recess means you can switch to a hand driver to finish the last turns and avoid stripping the head.

They come in a jar, 100 screws per jar. The jar format stacks and labels well in a van bin or shop drawer compared with a loose bag, which is why MRO and electrical stockrooms tend to standardize on it for high-use sizes like #10 x 2.

Yes, the JTTS31 #10 x 2 inch pan head tri-drive tapping screw is made in the USA, which matters on public and institutional jobs carrying domestic sourcing requirements on fasteners.
