The APEX MDA-12PT is a magnetic nutsetter designed for use with power screwdrivers and impact drivers in trade and industrial fastening applications. It features a 3/8 inch hex drive size and an overall length of 1.75 inches, making it a compact, direct-drive bit suited for repetitive fastening tasks. The integrated magnetic tip holds hex head fasteners securely during placement, reducing dropped hardware on the job. Electricians, HVAC techs, and general contractors reach for this type of bit when driving sheet metal screws, machine screws, and hex head fasteners in confined spaces or overhead work.
This nutsetter fits standard power screwdriver and drill driver chucks that accept hex shank bits. The 1.75 inch overall length suits close-quarters fastening where extended-length nutsetters would interfere with surrounding components. Typical applications include panel assembly, equipment mounting, ductwork fastening, and light structural work. Sold individually as a single-piece unit, it is also a practical replacement bit for worn or lost units in existing sets.
Designed as an OEM-style replacement nutsetter for use in standard 1/4 inch hex shank power screwdrivers and drill drivers accepting 3/8 inch magnetic nutsetters.
Install this bit into a power screwdriver or drill driver with the tool unpowered and the trigger released before inserting or removing any bit. Confirm the chuck or bit holder is fully seated and locked before applying torque. Follow applicable NEC or trade-specific fastener torque requirements for the fastener and material being driven. Inspect the magnetic tip periodically for wear or demagnetization, which can cause fastener drops during overhead or vertical work.
