Apex 4910-BX Phillips Power Screwdriver Bit 1/4 Hex

Product Description

The APEX 4910-BX is a No. 0 Phillips power screwdriver bit designed for use with 1/4 inch hex drive power tools and bit holders. The bit measures 3.5 inches in overall length, giving technicians and tradespeople added reach in confined spaces or deep fastener applications. With a body diameter of 0.130 inches and a precision-ground Phillips No. 0 tip, it seats securely in small fastener heads and resists cam-out under load. This bit is sold as a single piece and suits any trade professional who drives small-headed fasteners as part of routine equipment installation or service work.

The 4910-BX is appropriate for light-gauge fastener applications encountered in electrical panel work, HVAC equipment assembly, control board mounting, and other trade tasks that involve No. 0 Phillips screws. Its 1/4 inch hex shank is the industry-standard drive size accepted by quick-change bit holders, inline screwdrivers, and impact-rated bit adapters. The 3.5 inch overall length makes it a practical choice when a standard-length bit cannot reach a recessed or obstructed fastener location.

Key Features

• No. 0 Phillips tip for small-headed fasteners common in electrical and HVAC equipment

Compatibility

Designed for use with any 1/4 inch hex drive power screwdriver, drill driver, or quick-change bit holder that accepts standard power screwdriver bits.

Installation Notes

Seat the 1/4 inch hex shank fully into the bit holder before applying torque to avoid bit wobble or premature tip wear. When driving No. 0 Phillips fasteners in sensitive equipment such as control boards or electrical panels, follow applicable NEC or equipment manufacturer guidelines and power down circuits before servicing. Inspect the bit tip for wear before use and replace if the tip shows rounding or deformation that could damage fastener heads.
