Help identifying pieces in ambiguous wall anchor kit
OK, the yellow anchors do not go into the studs. They can be used in drywall, brick, masonry, etc when the proper size hole is drilled. Those big threaded anchors are for drywall. They have a sharp point and you screw them into the wall with a Phillips screwdriver and tighten them up so they indent a little into the drywall. Then one of your smaller silver screws get screwed into the center of the anchor. If you locate the stud, you can screw some of the silver screws directly into the studs after drilling a small pilot hole. The black caps just go over the installed screws to cover the heads for appearance.
