Apex AM-3MM-6 Hex Bit 3mm 6 Inch 25 Piece Set

Product Description

The APEX AM-3MM-6 is a 3mm hex bit designed for use with power screwdrivers, impact drivers, and hand drivers requiring a 0.25 inch drive. The overall length measures 6 inches, giving the technician added reach in confined or deep fastener locations. Each package includes 25 bits, making it a practical bulk option for shops and field crews with high-cycle fastening work. APEX manufactures these bits for industrial and trade use, with the hex geometry providing positive engagement and reduced cam-out compared to slotted or Phillips profiles.

This bit is suited for assembly work, equipment installation, and maintenance tasks across commercial and light industrial environments. Electricians, HVAC technicians, and mechanical contractors commonly use metric hex bits when working with imported equipment, panel hardware, and access covers fastened with 3mm hex socket screws. The 6 inch length accommodates recessed fastener applications where a standard-length bit would not reach.

Key Features

• 3mm hex size for metric fastener compatibility
• 0.25 inch drive fits standard power and hand driver chucks
• 6 inch overall length provides extended reach in tight or deep locations
• 25 pieces per package for high-volume or multi-tech use
• Industrial-grade hex geometry reduces cam-out during high-torque driving

Compatibility

Designed as a replacement-style hex bit for use with any 0.25 inch drive power screwdriver, impact driver, or hand driver chuck that accepts standard hex shank bits.

Installation Notes

Hex bits are installed and replaced by hand with no tools required. Confirm the driver chuck is fully seated and locked onto the bit shank before applying torque to prevent slipping. Inspect bits regularly for rounding or wear, and replace worn bits before use to avoid fastener damage. Dispose of worn bits in accordance with applicable shop safety practices.
