The Forgefix Lightning Bolt is a totally removable, rotation setting, medium to heavy-duty, thread forming anchor. It is ideal for either temporary or permanent anchoring into base materials including brick, concrete, hollow brick or block work. The flange head acts as a fixed washer, distributing the load under the bolt head. The Lightning Bolt is particularly well suited for close to edge or fixing, as it does not expand & burst the surrounding base material. It is through fixing, eliminating the need for marking & re-positioning. To use, simply drill through fixture & into the base & simply screw & tighten. The bolts are Zinc Yellow Passivated for increased resistance to corrosion & have Hex heads.
