Metallics JFMN68 Screw 6-32 x 1-1/4 FH SL Switch Plt (Jar 100)

At 1-1/4 inches, the JFMN68 is one of the longer 6-32 options and covers most cases where a box was set deep behind drywall, tile or a mud ring and the factory screw no longer bites. Measure from the face of your plate to the device mounting ear: if that gap plus the thread engagement you need is under 1-1/4 inches, this screw reaches. If the device is buried deeper than that, you want a 6-32 threaded machine screw longer still, or a box extender to bring the device forward.

Flat head with a slotted drive. A flat head is designed to seat into a countersunk or chamfered hole, so it finishes flush rather than standing proud, which is what you want on a finished cover plate. The slot takes a standard flat blade driver, no bit change needed if you are already working with a straight tip electrician's screwdriver.

100 screws per jar. The jar pack is the bulk format a service truck or shop drawer gets stocked with, so you are buying a count rather than a single fastener. For a property maintenance crew replating a run of units, one jar covers a lot of openings.

Both uses are the same 6-32 thread, so a 1-1/4 inch flat head will run into a device yoke or into a plate. In practice the long length is most often used plate side or where extra reach is needed; standard device-to-box mounting usually uses the shorter screw that ships with the device. If you use these to mount a device, make sure the extra length is not bottoming out against the back of the box or against conductors.
