1. Bolting into steelwork to allow smooth face for overboarding and 2. Bolting mono-pitched double timber rafters beside large skylights to resist twisting of timbers cut and fixed on site and avoid subsequent splitting of plasterboard at a later date.
50 M10x115mm Joyner Bolts used.
Conclusion & Feedback
Joyner Bolt’s square head size allowed increased torque to tighten timbers and prevented timbers from twisting and causing future rework.
