Product Description

The IRWIN IWAF243516 is a nut driver power screwdriver bit designed for use with power tools and impact-rated screwdriver handles that accept a 1/4 inch hex shank. The bit drives 5/16 inch hex fasteners and measures 2-9/16 inches in overall length, providing enough reach for standard fastener-driving tasks. Weighing approximately 0.07 pounds, it is a compact, single-piece accessory suited for electrical, HVAC, and general mechanical applications where repetitive nut driving is required. Licensed electricians, HVAC technicians, and plumbers commonly use nut driver bits like this for panel work, equipment installation, and fixture mounting.

This bit fits applications where a 5/16 inch hex nut or bolt head must be driven quickly with a power screwdriver or drill driver. The 1/4 inch drive shank is the industry-standard quick-change size, making it compatible with bit holders, extension bars, and power drills used in residential and light commercial service work. It is sold as a single unit, making it a practical replacement or addition to an existing bit set.
