Developer: not disclosed
Contractor: Beck Interiors, Chessington
Supplier: Travis Perkins, Woolwich
Project Completion: ongoing (Oct 2016)
Contractor ordered Joyner Bolt after reading about Joyner Bolt and completing online research when seeking a fixing to join new to old timbers throughout the whole building.
1000 plus M12x180mm Joyner Bolts used to date.
Conclusion & Feedback
Contractor impressed by the hole size tolerance provided by the square spiked head of Joyner Bolt. This is proving to be hugely beneficial for speed and time given the awkward working spaces throughout this project. Furthermore the head allows the bolts to be tightened to a much greater torque level than traditional coach bolts creating a stronger framework for the extensive refurbishment in progress.
