M8 Genuine Thunderbolts with Hexagonal Head

Hexagonal Head Genuine Thunderbolt
The unique patented concave thread design taps its own thread and provides a rapid, low torque installation with exceptional pull out resistance. It also allows the user to adjust or remove the bolt ensuring a secure and accurate installation. This stress free, non-expansion through fixing is the new solution for medium duty anchoring into concrete, brick, stone, wood and concrete block replacing the need for traditional anchors such as through bolts, shield, sleeve and drop-in anchors
Always 'over drill' the hole by 20mm
The M8 Bolt requires a hole clearance through the fixture of 10mm
Available in pack sizes of 2, 4, 6, 10, 25, 50 or 100.
