Klein Tools 32527 11-in-1 Screwdriver Nut Driver Set

Product Description

The KLEIN TOOLS 32527 is an 11-in-1 screwdriver and nut driver designed for electricians, HVAC technicians, and other trade professionals who need versatile fastening capability in a single tool. At 7.75 inches in overall length with a 3-inch shank, the 32527 packs eleven functions into a compact, cushion-grip handle finished in yellow and black for easy identification in a tool bag. The handle provides a comfortable, high-torque grip suited to both overhead and confined-space work. This multi-bit driver eliminates the need to carry multiple individual drivers on residential and commercial job sites.

The 32527 is well suited for electrical, HVAC, and general mechanical service work where a mix of bit types is routinely required. The included bit assortment covers Phillips, Square, and Slotted drive types, plus three nut driver sizes for common hex fasteners. The added Schrader valve insertion and core removal functions make this tool particularly useful for HVAC and refrigeration technicians servicing refrigerant access ports. It is appropriate for both residential service calls and light commercial applications.
