OATEY 33930 1-1/2 in. x 3 in. 18 Gauge Self-Nailing Stud Guard – 2-1/2 in. between points

The Oatey 33930 is a galvanized steel plate that nails over a stud or plate where pipe or wire passes through, so a drywall screw or finish nail driven later hits steel instead of the line behind it. It protects both plumbing and electrical runs. The self-nailing feature means the plate has its own integral points, so you tap it in place without separate fasteners.

The 33930 measures 1-1/2 in. x 3 in., with 2-1/2 in. between the nailing points. The 1-1/2 in. dimension matches the face width of a nominal 2x4 or 2x6 stud, so one plate covers the full stud face at the notch or bore.

The 33930 is made of 18 gauge steel, which is the common nail-plate thickness used to deflect drywall screws and finish nails at notched or bored studs. It is a deflection plate, not armor for structural fasteners.

No extra fasteners. The 33930 has Oatey's self-nailing feature, meaning the points are formed into the plate itself, so you set it over the notch or bore and drive it in with a hammer. That is what keeps it fast when you are plating a whole wall of holes in one pass.

Both. Oatey lists the 33930 as providing protection for pipes and wiring, so it works over NM cable runs as well as copper or PEX lines through a notched or bored stud.

The plate is galvanized steel, so it holds up to the incidental moisture of a wall cavity better than bare steel. It is a construction-grade metal part, not a stainless or coated-for-exposure product, so it is intended for concealed framing rather than open exterior exposure.

One part number covers it: Oatey model 33930, the 1-1/2 in. x 3 in. 18 gauge self-nailing stud guard with 2-1/2 in. between points. There are no finish or size options to specify.

Each 33930 plate weighs 0.059 lb, so even a case quantity for a full rough-in adds very little freight weight. Useful if you are bundling them into a larger plumbing or electrical material order.
