Stanley 66-176-A Slotted Screwdriver 5/16 in Square Shank

Product Description

The STANLEY 66-176-A is a standard slotted screwdriver built for general-purpose fastener work across trades and job sites. The blade measures 5/16 inches in width and 6 inches in length, with an overall length of 11 inches for extended reach in tight or deep access points. A square shank design allows a wrench to be applied directly to the shank when extra torque is needed on stubborn fasteners. The acetate handle provides a firm grip and resists common shop solvents. This screwdriver is suited for electricians, HVAC technicians, plumbers, and general service professionals who need a reliable hand tool for panel work, equipment access covers, and field service tasks.

The 66-176-A is intended for standard slotted screw driving in residential and light commercial applications. The 6-inch blade gives adequate reach for recessed fasteners inside electrical enclosures, HVAC equipment cabinets, and plumbing access panels. The square shank makes it particularly useful when fasteners are corroded or overtightened and additional mechanical advantage is required. It is appropriate for any trade professional who regularly works with slotted-head fasteners as part of routine installation or service work.

Installation Notes

Power down or de-energize any equipment before using a screwdriver inside electrical panels or control enclosures, in accordance with applicable NEC lockout/tagout procedures. Inspect the blade tip for wear or deformation before use, as a damaged tip can slip and damage fastener heads or surrounding components. When applying a wrench to the square shank for added torque, use only an appropriately sized open-end or adjustable wrench and apply force steadily to avoid slipping.
