The STANLEY 64-104-A is a No. 4 Phillips screwdriver built for heavy-duty fastening tasks where a larger drive size is required. The 8-inch round shank provides the reach and rigidity needed to seat large Phillips-head fasteners in deep or recessed applications. The plastic handle offers a firm grip during installation and removal. This screwdriver is a standard hand tool used by electricians, HVAC technicians, plumbers, and general trades professionals working on equipment panels, junction boxes, access covers, and mechanical assemblies that use No. 4 Phillips fasteners.
The 64-104-A is suited for residential and commercial service work where large-format Phillips screws are common, including equipment enclosures, sheet metal screws on HVAC cabinets, electrical panel covers, and similar fastening points. The 8-inch blade length allows access to recessed fastener locations that shorter drivers cannot reach. It is sold individually and is appropriate as a primary or supplemental hand tool on a service van or job site.
Designed as a standard No. 4 Phillips hand screwdriver compatible with any large-format Phillips-head fastener requiring a No. 4 drive point.
This tool is used by licensed tradespeople across HVAC, electrical, and plumbing disciplines. Always power down or de-energize equipment before removing or installing fasteners on electrical panels, control boards, or equipment enclosures. Inspect the tip for wear before use — a worn Phillips tip can damage fastener heads and slip under torque. Apply steady axial pressure while turning to maintain proper engagement with the fastener recess.
