Metallics TM82 6-32 x 1-1/2 in. Truss Head Combo Receptacle Screws - Steel Zinc - Each

At 1-1/2 inches of length, the Metallics TM82 screw is the long version electricians keep on the van for exactly that situation: deep boxes, plaster or mud rings, and setups where a standard short device screw bottoms out before the yoke pulls tight. It threads 6-32, which is the standard device mounting thread used on receptacle and switch yokes, so it drops into the tapped ears of the box or ring without any adapter.

Any device with the usual 6-32 tapped mounting holes takes them, which covers standard duplex receptacles, toggle and decorator switches, and most device rings from any manufacturer. The 6-32 thread is the common device standard, so brand is not the deciding factor; length is. Use the 1-1/2 inch TM82 where the shorter screw that shipped with the device is too short.

Both. The TM82 has a combo head, slotted and Phillips in the same recess, so whichever driver is already in your hand works. That matters on device work where you are switching between screw types on the same box and do not want to swap bits.

The TM82 is steel with a zinc plating, which handles normal indoor and dry commercial interior work, including garages and unheated spaces. Zinc plating is a sacrificial coating, not stainless, so for wet, coastal, or corrosive environments spec a stainless device screw instead.

The truss head on the TM82 is wide and low, so it spreads bearing across the slotted mounting ears of a receptacle or switch yoke and sits shallow enough that the wall plate still seats flat over it. A tall head can interfere with the plate on a tight device.

Order it as Metallics TM82. That designation covers the 6-32 x 1-1/2 inch truss head combo drive receptacle screw in zinc plated steel.
