10 x 100 Concrete Bolt Index Hex Head Flange in A4 Stainless Steel

Concrete bolts, similar to Thunder bolts. Offered in a number of materials and head types, these bolts are 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. This example is provided with a hex flanged head.
