(32 mm) Anchor Color: Blue Screw Head Style: Pan Head Phillips Installation Instructions: Drill a pilot hole through the wall at your desired spot. Push the anchor into the hole and tap it lightly with a hammer until it fits snugly and its end is flush with the wall . Use a manual or electric screwdriver to drive the screw into the anchor. Technical Details: The type of anchor that is suitable for your project will be based on the wall material, the weight of the load being hung, and how it can be installed and removed . When trying to choose a wall anchor, consider first and foremost the project load and load conditions for the job. For our anchors the 12 Drywall Shear is 23 lb and Concrete Shear is 250 lb . It is advised to never exceed the weight limit, especially if you're using them to hang valuable items on the wall. For particularly heavy items, you can use multiple anchors to distribute the weight evenly and help prevent the fasteners from pulling out of the wall. Like our product here, larger anchors that accept bigger screws are generally more secure. These are not suitable for use on ceilings as downward pressure could cause the anchor to slip out.
