This innovative head design enables pre-fastening to the final fastening of a bolt by increasing the surface contact area to the bolt walls. Increasing the contact area not only enhances the fastening strength but also prevents both the wrench head and the bolt walls from wearing out. *EL/ARMOUR EIGHT TOOL original premium hard plating Superior performance with outstanding abrasion and rust resistance EL/ARMOUR® is a new-generation plating that was developed to advance EIGHT TOOL quality further under environmental awareness.
