The Stanley FatMax FMHT0-62620 is an 8mm flared tip screwdriver with a bolster for additional torque. The 8mm tip handles larger slotted screws found in industrial switchgear, heavy-duty hinges, older lock mechanisms, and marine fittings where flat head screws remain the standard fastener type.

The bolster is a hexagonal collar at the blade base that accepts a spanner or wrench for extra turning force. This is the feature that separates a bolster screwdriver from a standard driver, and it matters most when breaking free corroded or paint-sealed screws where grip alone cannot generate enough torque. The alternative without a bolster is to resort to mole grips on the shaft, which damages the blade finish and provides poor control.

The FatMax bi-material handle has a soft outer grip over a rigid core. The larger 8mm driver has a proportionally larger handle than the 6.5mm version, giving a bigger contact area across the palm for the higher forces this size generates. The handle material resists acetone, solvents, and cleaning agents, so it holds up in industrial and marine environments where chemical exposure is routine.

The chrome vanadium steel blade is hardened, tempered, and finished with a black oxide coating for corrosion resistance. The 175mm blade length gives the extra reach needed for deeper fittings and recessed fixings without sacrificing the rigidity needed for heavy torque application.
