Minerallac 52416-6 – Frequently Asked Questions
1) Will a Minerallac 52416-6 8-32 screw thread into a standard electrical box or device plate tapped hole?
Yes. The 52416-6 is an 8-32 machine screw with a Class 2A external thread, which is the standard commercial fit for the tapped 8-32 holes in steel outlet boxes, mud rings, and device plates. Because it is a machine screw, it needs a pre-tapped hole, a nut, or a threaded enclosure boss. It will not cut its own thread in sheet metal.
2) Is 1 inch too long for mounting a cover plate on an outlet box?
For a flat cover or device plate, 1 inch is usually more length than the tapped boss needs, and the excess will bottom out or protrude into the box. The 52416-6 measures 1 inch under the head, which suits panel hardware, stacked gaskets, extension rings, or anywhere you are pulling through added thickness. For a plate sitting directly on a mud ring, a shorter 8-32 screw is the better pick.
3) What screwdriver do I need for the Minerallac 52416-6 machine screw?
Either a #2 Phillips or a flat-blade driver. The head is a combination Phillips/slotted drive, so whatever is already on your belt will turn it. The #2 Phillips is the correct size, so don't drop down to a #1 and risk camming out the recess.
4) How much does the round head on the 52416-6 stick up off the surface?
The round head measures 0.298 inch across and stands 0.114 inch tall. That domed profile seats on the surface rather than sinking in, so it is not a substitute where a countersunk flat head is specified, such as a flush device plate prep. Where you need clearance under a panel door or behind a trim, allow for that 0.114 inch of head height.
5) Can I use zinc plated 8-32 machine screws outdoors or in a damp location?
The 52416-6 is zinc plated steel, which handles indoor and generally dry environments well. Zinc plating gives sacrificial corrosion resistance, not the long-term protection of stainless, so for wet locations, washdown areas, coastal exposure, or direct weather, specify a stainless 8-32 machine screw instead.
6) Do these 8-32 screws come with nuts or washers?
No. The 52416-6 ships as the screw only. It is built for pre-tapped holes and threaded enclosures, so if you are through-bolting a panel or bracket you need to order 8-32 nuts and any flat or lock washers separately.
7) What is the Minerallac part number and size offered for this round head machine screw?
Part number 52416-6, in the 1 inch length, 8-32 thread. Silver zinc plated steel with a round head and combo Phillips/slotted drive.
