Eye Bolt
Dayton Superior Tilt-Up Handbook
The F49 Eye Bolt is an F48 Eye Nut supplied with a specified length of coil rod that has been welded in place. In order to develop the F49 eye bolt’s rated load, the shoulder must be tightened securely against the face of the concrete.
The F48 Eye Nut and F49 Eye Bolt are intended for straight tensile loading only; pulling or lifting at an angle drastically reduces the safe working load and is not recommended.

Tilt-up is a job-site form of precast concrete construction. It involves prefabricating concrete wall sections, then lifting or tilting them up. Once they are in position, the panels are temporarily braced until they are tied into the roof and floor system. It is a fast, simple, and economical method of construction, which most recently been adapted successfully to multi-story structures.
Dayton Superior has been instrumental in developing and manufacturing the hardware necessary in the most critical steps for this method of construction — that of lifting the wall panel and placing it without damage. Our product development team continues to strive to provide a complete package for economical and safe construction of tilt-up buildings.
