Milwaukee 48-22-2051 No. 1 Square Drive Screwdriver

Product Description

The MILWAUKEE 48-22-2051 is a No. 1 square drive screwdriver with a 4-inch blade, built for trade professionals who need a reliable hand tool for fastening and driving square-head fasteners. The square drive tip engages Robertson-style screw heads with positive contact, reducing cam-out during installation. This screwdriver is suited for electricians, HVAC technicians, plumbers, and general trade use wherever square-drive fasteners appear in panel work, equipment installation, and fixture mounting.

The 48-22-2051 fits standard residential and light commercial applications where No. 1 square drive fasteners are specified. It is a practical addition to any trade tool kit and is commonly used during rough-in and finish work across electrical, mechanical, and plumbing trades. The 4-inch blade length provides adequate reach for most fastener access points without excessive bulk.

• 4-inch blade length suited for confined and standard access points

Installation Notes

This tool requires no installation. Ensure the square drive tip is fully seated in the fastener recess before applying torque to avoid tip or fastener damage.
