Features

• All bits are magnetized - helping the bit grip the screw and prevent cam-out
• Compression forged tip - for an ideal fit and to reduce breakage
• Patented spiral impact zone - to distribute torque evenly
• Full body hardness - for a longer service life
• Premium quality S2 raw material

About What is Impact

• On standard driver bits, the tip absorbs all the concentrated torque.
• High impact loading leads to distorting, rapid tip failure, and breakage.
• Thunder Zone impact driver bits, with an engineered spiral torsion zone, distribute the applied impact evenly throughout the torsion zone, allowing higher impact loads and greatly extended bit life.
