The Stanley FatMax Xtreme Anti-Vibe Claw hammers are defined by a 75% larger strike face and narrow curve claw. They have torsion control to prevent twisting and a patented tuning fork design to reduce the effects of harmful vibrations.

The one-piece solid forged head gives a larger sweet spot and better balance. The range also incorporate a magnetic nail starter for hands-free use and a soft-grip handle which reduces fatigue and allows for multiple holding positions.
