The APEX MDA-10 is a magnetic nutsetter bit designed for power screwdrivers and impact drivers used in trade and industrial fastening applications. The magnetic tip holds hex-head fasteners securely during driving, reducing dropped hardware in tight or overhead work. With a 5/16 inch hex size and an overall length of 1-3/4 inches, this bit suits standard hex-head screws, sheet metal screws, and machine bolts commonly encountered in HVAC panel assembly, electrical enclosure work, and equipment installation. It is a single-piece bit sold individually.
This nutsetter fits applications where controlled, repeatable fastening is required on hex-head fasteners. The compact 1-3/4 inch overall length works well in confined spaces typical of equipment cabinets, control panels, and junction boxes. Trade professionals in HVAC, electrical, and plumbing service frequently use magnetic nutsetters like this during equipment installation and preventive maintenance where standard nut drivers are impractical with a power tool.
Designed as an OEM-style replacement or standard accessory for 1/4 inch hex-drive power screwdrivers and impact drivers accepting magnetic nutsetter bits.
Installation requires no special tools beyond a 1/4 inch hex-drive power screwdriver or impact driver. Always ensure the tool is powered off and the bit is fully seated in the tool chuck before use. Inspect the magnetic tip for wear or reduced holding strength before each use, and replace the bit if retention of fasteners becomes unreliable.
