The Stanley FatMax FMHT0-62623 is a PH3 Phillips tip screwdriver with a hexagonal bolster for high-torque applications. PH3 is the larger Phillips size used in heavy-duty fixings, structural brackets, larger hinges, and industrial equipment where the standard PH2 is too small to fill the screw recess properly.

The bolster accepts a spanner at the blade base, allowing significantly more torque than hand grip alone. This matters on PH3 screws because they are typically used in applications where higher clamping forces are required, and corroded or over-tightened PH3 screws need substantial force to break free. The wrench-on-bolster technique gives controlled torque without the cam-out risk that comes from simply pushing harder on the handle.

The FatMax bi-material handle is sized proportionally for the PH3 blade, giving a larger palm contact area that matches the higher forces this driver is designed to transmit. The soft outer grip absorbs vibration and provides a non-slip surface, while the rigid core maintains the alignment between handle and blade under load. The handle material resists acetone, solvents, and other chemicals encountered on site.

The chrome vanadium steel blade is precision-machined at the PH3 tip for a tight fit in the screw recess. Loose tip engagement is the primary cause of cam-out on Phillips screws, so the machining quality at the tip directly affects how reliably the driver transfers torque. The 150mm blade length provides the reach needed for deeper fixings and recessed fittings.
