Apex AM-2.5MM-4 Hex Power Screwdriver Bit 4 in

Product Description

The APEX AM-2.5MM-4 is a hex-drive power screwdriver bit designed for use with power screwdrivers, impact drivers, and drill-driver tools in trade and industrial applications. With an overall length of 4 inches (102 mm) and a 2.50 mm hex size, this bit delivers consistent drive engagement in tight or extended-reach fastening situations. It is supplied as a single piece and is well-suited for electricians, HVAC technicians, plumbers, and other trade professionals who rely on powered fastening tools for panel work, equipment assembly, and fixture installation.

This bit is applicable in residential and commercial service environments wherever a 2.50 mm hex power bit is required. Its 4-inch overall length makes it practical for reaching fasteners in recessed or obstructed locations, such as inside electrical enclosures, HVAC unit cabinets, and equipment access panels. Sold individually, it integrates directly into standard power tool bit holders that accept hex-shank bits.

Key Features

• 2.50 mm hex bit size for precise drive fitment
• 4-inch (102 mm) overall length for extended reach in confined spaces
• 0.2500 inch drive size for compatibility with standard power tool bit holders
• Designed for use with power screwdrivers, drill-drivers, and impact drivers
• Single-piece packaging for individual replacement or addition to a tool kit

Compatibility

Designed as an OEM-style replacement or direct-fit power screwdriver bit for standard hex-shank power tool bit holders accepting a 0.2500 inch drive.

Installation Notes

Insert the bit fully into the tool holder and confirm it is seated and locked before applying torque. Ensure the fastener head is properly aligned with the bit before driving to prevent cam-out or damage to the fastener. Inspect the bit for wear or deformation before each use and replace if the hex geometry shows signs of rounding. No special trade licensing is required, but follow all applicable workplace and jobsite safety guidelines when operating powered hand tools.
