Metallics MWDPZ114K Anchors 1-1/4 Pn Ph Walldog Ancr St-zn (Clam100)

Overall length is 1-1/4 inches, so after the thickness of whatever you are fastening down (a conduit strap, a bracket ear) you have the remainder for embedment. For thin fixtures that is plenty; if you are stacking a thick standoff or plate, step up to a longer Walldog instead.

The MWDPZ114K is a 1-1/4 inch pan head Phillips Walldog anchor in zinc-plated steel. A Walldog is a self-drilling masonry and drywall screw anchor: it drives directly into the base material without a separate plastic sleeve or lead shield, so one fastener does the job. The pan head with Phillips drive gives a flat bearing surface, which is what you want under a conduit strap, device bracket, or box mounting ear.

They ship 100 per clamshell. That is a single counted pack, so if you are mounting straps or boxes across a whole floor, order by the multiple of 100 you need rather than expecting a bulk box.

The anchor is steel with a zinc plating, which is a general indoor and protected-location finish. It resists handling corrosion and dry interior conditions well. For direct weather exposure, wet locations, or coastal work, specify a hot-dip galvanized or stainless fastener instead.

No. A Walldog is a one-piece anchor, so there is no plug, sleeve, or shield to insert first. You drill the pilot hole and drive the anchor. That is the main reason electricians choose them over plastic-anchor-and-screw assemblies for repetitive strap and box mounting.

Order Metallics MWDPZ114K. That number covers the 1-1/4 inch pan head Phillips Walldog anchor in zinc-plated steel, packed 100 to a clamshell. There is one configuration under that part number, so there is no finish or length suffix to add.

It is a Phillips drive pan head, so a standard Phillips bit in a drill or impact driver runs them. No specialty torx or hex bit required, which matters when a crew is setting hundreds of these in a day.

Metallics lists it on the electrical side of the line, and the 1-1/4 inch pan head Walldog is the size electricians reach for on one-hole and two-hole conduit straps, box mounting ears, and small device brackets. Nothing stops a general contractor from using it for the same light-duty fastening, it just happens to be specified from the electrical fastener program.
