Index Concrete Bolts in Bright Zinc Plated (BZP) Steel
Concrete bolts, similar to Thunder bolts. These are BZP (bright zinc plated) self tapping anchors, which can be used, not only in concrete, but in brick, marble, stone, wood and hollow core slabs. Concrete bolts are quick and easy to use, requiring no wall plugs and can be unscrewed if needed. As these bolts do not expand or apply expansion stress, they can be used close to the edge of the fixing material.
