The RD3 Kit is suitable for use in solid/hollow wall, concrete, block, or brick applications. When used in hollow walls, such as drywall or plywood, the wings will splay out to provide a more secure installation and higher pull-out load. The anchor has a lip to prevent falling into deep holes or hollow walls.For hard wall applications, use the size of the anchor to determine hole size for installation. For drywall or soft applications it is recommended to use the smallest hole that will enable a tight fit of the anchor. These anchors are not recommended for use in overhead applications or where holding values are critical.Kit Contains(100) Conical Anchors(100) #6 x 1'' Phillips/Slotted Sheet Metal Screws(1) 1/4'' Carbide Tipped Masonry Drill BitMain FeaturesAnchor Type ConicalDrive Type Phillips/SlottedHead Type PanScrew Size #8 x 1''Bit Size #2Anchor Diameter 1/4''Anchor Length 1''Material PolyethyleneColor RedNumber of Pieces 201General InformationName: Dottie RD3 #8 Red Conical Anchor Kit with Pan Head Combo Drive Screws, L.H.
