The Stanley FatMax 0-65-317 is a PH4 Phillips screwdriver, the largest standard Phillips size. PH4 fasteners are found in heavy commercial and industrial applications: large cabinet hardware, industrial machinery covers, and heavy electrical enclosures. Most tradespeople will not need a PH4 daily, but when the application calls for it, using the correct size is the difference between a clean drive and a stripped recess.

The 200mm chrome vanadium steel blade gives the reach needed for recessed fixings and deeper assemblies. The blade is hardened and tempered for durability under the higher torque loads that PH4 fasteners demand. The tip is precision machined to match the PH4 recess geometry, ensuring maximum contact with the fastener walls to reduce cam-out and extend the life of both driver and screw.

The oversized FatMax bi-material handle is proportioned for the PH4 blade, providing enough surface area for a secure two-handed grip when extra torque is needed. The soft outer layer absorbs vibration and prevents slipping, while the rigid core transmits force efficiently to the blade. Chemical resistance in the handle material protects against acetone, solvents, and workshop fluids.
