The DEWALT DW2222B is a magnetic socket driver designed for screw driving applications in trade and construction environments. Measuring 5/16 inches by 2-9/16 inches, this driver bit features a magnetic tip that holds fasteners securely during placement, reducing dropped hardware and improving single-hand operation. The compact form factor fits standard hex-shank drill/drivers and impact-ready tools commonly used by electricians, plumbers, HVAC technicians, and general contractors. At 0.07 pounds, it adds virtually no weight to the tool setup. It is sold individually and suited for repetitive fastening tasks where bit retention and consistent drive depth matter.
This socket driver is used across residential and light commercial applications wherever 5/16 inch hex fasteners are required. Common scenarios include panel work, equipment mounting, junction box installation, and sheet metal assembly. The magnetic retention is particularly useful when working overhead or in confined spaces where retrieving a dropped fastener is not practical. Tradespeople who run high volumes of fasteners daily will find the bit length appropriate for standard-depth driving without excessive wobble.
Designed for use with standard hex-shank drill/drivers and power screwdrivers accepting 1/4 inch hex bits, suitable for 5/16 inch socket head fasteners across general trade and construction applications.
Insert the hex shank fully into the tool chuck or bit holder before driving to ensure secure seating. Confirm the fastener is properly seated in the magnetic socket tip before applying torque. For impact driver use, verify the bit is rated for impact use in your specific application. Inspect the magnetic tip periodically for wear or reduced retention strength and replace the bit as needed to maintain consistent drive performance.
