M5 & M6 Genuine Countersunk CSK Thunderbolts with Torx Head

Available in pack sizes of 4, 8, 12, 24, or 50.

Simply drill a hole using the correct masonry drill bit, remove the dust and debris and wind in. No need for plastic plugs.

These bolts are classed as non-expansion anchors which means they won't stress the concrete when fixing.

Countersunk Torx 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

  • Use 5mm Hammer Drill Bit for the M5 Thunderbolt
  • Use 6mm Hammer Drill Bit for the M6 Thunderbolt
