Metallics SPT300 Screws 6-32 X 1 Ov Tr Span Switch Plt SS (Clam 50)

Yes. The SPT300 is a 6-32 thread screw with 32 threads per inch, which is the standard machine screw thread used on switch and receptacle plates and on the mounting yoke of standard wiring devices. At 1 inch long it reaches deeper than the short screws packed with most plates, so it works where the device sits recessed in the box or behind thicker wall material.

A driver is included. The SPT300 uses a spanner (two-hole) drive, and the clamshell comes with the 00SP6B spanner insert bit, so you do not need to buy a separate tool to install or remove them. The insert bit fits a standard 1/4 inch hex driver or bit holder.

The spanner drive has two small holes rather than a slot or Phillips recess, so a standard screwdriver, coin, or knife blade cannot get purchase on it. That makes the SPT300 a practical deterrent on switch and receptacle plates in schools, detention areas, transit spaces, and public restrooms. Keep the included 00SP6B bit with your maintenance tools, since the plate cannot be removed without it.

Yes on both. The SPT300 is flagged Buy American compliant and ARRA compliant, with country of origin United States. That covers the documentation most federal, state, and institutional procurement packages ask for on fasteners.

They are made of 18-8 stainless steel, so they hold up in damp interior locations like restrooms, kitchens, and locker rooms far better than the plated steel screws that ship with most plates. The head is an oval/pan style that seats into a countersunk plate hole.

The SPT300 ships as a 50-piece clamshell, with 50 each as the order minimum. Other lengths and pack quantities in this tamper-resistant spanner line are available by request.

For a device mounted flush in the box, 1 inch leaves extra thread hanging past the yoke, which is harmless but can bottom out against wiring in a crowded box. The 1 inch length on the SPT300 earns its keep when the device is set back behind tile, panelling, or a thick wall covering, or when you are mounting through a spacer. If your devices all sit flush, a shorter length in the same spanner line can be requested.

The line is intended for the electrical, plumbing, heating and air conditioning trades, so the same 6-32 spanner screw gets used on any cover or access plate tapped 6-32 in those systems, not just switch and receptacle plates.

The clamshell weighs 0.27 lbs and measures 3.75 x 2.75 x 1.5 inches, small enough to drop in a tool pouch or stock on a van shelf for a plate-standardization job.
