Milwaukee Tool 49-66-0535 Impact Nut Driver Bit Set 10pc

Product Description

The MILWAUKEE TOOL 49-66-0535 is a 10-piece set of SHOCKWAVE Impact Duty magnetic nut drivers designed for use with 3/8 inch drive impact tools. Each driver measures 2-9/16 inches in overall length and accepts a 1/4 inch hex fastener. The magnetic tip retains nuts and hardware during placement, reducing dropped fasteners on the job. Built to handle the high-torque demands of impact drivers and wrenches, these bits are a standard consumable for HVAC, electrical, and plumbing tradespeople who fasten sheet metal, electrical enclosures, and equipment panels at volume.

This set is suited for residential and light commercial trade work where speed and fastener retention matter. The 1/4 inch hex size is common across HVAC equipment panels, junction boxes, and mechanical room hardware. The 3/8 inch drive shank interfaces directly with standard 3/8 inch impact wrenches and adapters, making this set a straightforward grab for techs already running 3/8 inch drive tools on the truck. Ten pieces per set provides working inventory to rotate through and replace worn bits without downtime.

Installation Notes

Install and replace impact nut driver bits with all tools powered down and trigger locked out. Inspect bits for deformation or wear before each use, as damaged impact bits can slip under load and round fastener heads. These bits are intended for impact-rated tools only and should not be used in standard drill-drivers at sustained high torque. Replacement of worn bits is a routine consumable task requiring no special certifications.
