Milwaukee Tool 49-66-0502 Impact Nut Driver Bit Set 10pc

Product Description

The MILWAUKEE TOOL 49-66-0502 is a 10-piece set of SHOCKWAVE 1/4 inch magnetic impact nut drivers designed for use with power impact drivers and impact-rated drills. Each driver measures 1-7/8 inches in overall length and accepts 1/4 inch hex fasteners. The magnetic tip holds nuts and screws securely during driving, reducing dropped hardware on the job. These bits are engineered to handle the high-torque demands of impact tool operation, making them a reliable choice for HVAC techs, electricians, plumbers, and other trade professionals who drive sheet metal screws, hex-head fasteners, and equipment enclosure hardware at volume.

This set is well suited for residential and light commercial service work where 1/4 inch hex-head fasteners are common — including ductwork assembly, electrical panel and junction box cover installation, and equipment access panel fastening. The compact 1-7/8 inch length allows use in tighter clearances compared to longer nut driver formats. Ten identical drivers in a single package means spares are on hand for multi-tech crews or high-volume installs where bit wear is a regular occurrence.

Key Features

• SHOCKWAVE impact-rated construction handles high-torque impact driver output without premature failure
• Magnetic tip retains 1/4 inch hex fasteners during driving and reduces dropped hardware
• 1-7/8 inch overall length suits confined spaces common in HVAC, electrical, and plumbing service
• 1/4 inch hex shank fits standard quick-change impact driver chucks
• 10-piece set provides redundancy for multi-tech jobs or extended service schedules

Compatibility

Designed for use with any 1/4 inch hex quick-change impact driver or impact-rated drill driver. Sized for 1/4 inch hex-head fasteners commonly found in sheet metal, electrical, and mechanical equipment applications.

Installation Notes

Install and remove only with the impact driver powered off and the trigger released before changing bits. Verify the bit is fully seated in the chuck before operating the tool. These are impact-rated bits intended for power tool use only — hand-driver use is not the intended application and may result in reduced service life. Follow applicable NEC, IFGC, or IPC guidelines for fastener requirements in your specific trade application.
