25 packs of Sleeve Anchors.
Comes in sizes: 8 x 65, 10 x 77, 10 x 97, 12 x 75, 12 x 99, 12 x 129.
This anchor is used with a pre drilled pilot hole and then tightened with a hex nut to spread the wings on the fixing for a very high strength and high pull out rating.
These require a pilot hole for installation. The pilot hole should be the same size as the fixing.
