• Minimises locknut damage
• Designed to fit a number of different nut sizes
• Spanners with zinc coating, corrosion resistant handle

The TMFN impact spanners are designed for safely tightening and loosening larger locknuts, especially after driving up a large bearing onto a tapered seating. Made of spheroidal graphite cast iron, they have a special impact surface allowing for optimum transmission of impact energy to the nut.
