Leviton 84020-40 – Frequently Asked Questions
1) What does the Leviton 84020-40 screw actually mount - the wallplate or the device?
It is a device mount screw, the fastener that holds a switch, receptacle, or other wiring device strap to the box. The Leviton 84020-40 is sized for 1-gang device and wallplate mounting hardware. If what you need is the small screw that holds a cover plate face on, that is a separate wallplate screw, not this part.
2) Will a 1-gang Leviton locking device screw work on a 2-gang or 3-gang plate?
It is a 1-gang part. The 84020-40 is sized for single-gang device straps and wallplate hardware, so for 2-gang or larger assemblies you need the screw specified for that gang count rather than this one. Quantity is the other thing to watch: most single devices take two mounting screws, so order accordingly.
3) Why use a locking device mount screw instead of a standard one?
The locking design on the Leviton 84020-40 keeps the device strap and wallplate seated so the assembly does not back off from vibration or from repeated plugging and unplugging. It also makes the mounting less casual to disturb, which is why it gets specified in tamper-resistant installs in schools, healthcare, and other institutional work.
4) Will a stainless device mount screw hold up in a damp or corrosive location?
302 stainless is corrosion resistant, which is why this screw gets used where plated steel would rust out - damp mechanical rooms, kitchens, coastal and wash-down adjacent areas. For a property manager standardizing hardware across a building, it is the same screw you can put in both dry interior and damp locations rather than stocking two.
5) What is the Leviton part number for the 1-gang stainless locking device mount screw?
Order it as Leviton 84020-40. That is the manufacturer part number for the 302 stainless, non-magnetic, 1-gang locking device mount screw, and it is the number to quote if you are matching screws already installed on a job.
