Screwdriver Bit Set Makita E-03137 2 pcs PH 2 1/4 Security Hex

The Makita E-03137 screwdriver bit set contains two 25 mm bits: a PH2 Phillips and a 1/4" security hex bit. Designed for use with compatible bit holders, hand drivers and cordless screwdrivers, these bits provide accurate engagement with fasteners and compact length for access in confined spaces. The set is intended to deliver consistent fit and repeatable results across a range of assembly, repair and maintenance tasks.

Advantages

Both bits are manufactured to deliver stable torque transfer and reduced cam‑out when used with matched drivers. The 25 mm length balances reach and control, allowing access to shallow recesses while remaining short enough for controlled operation. The security hex bit features a tamper‑resistant design suitable for fasteners requiring a pin‑in‑hex engagement.

Suitable for

• General assembly and disassembly of household and furniture items
• Electronics and appliance maintenance where short bits improve access
• Installation of fixtures and fittings requiring a PH2 or tamper‑resistant hex
• Workshop and on‑site repair tasks with powered screwdrivers or bit drivers

Key specifications

• Contents: 2 bits (PH2, 1/4" security hex)
• Length: 25 mm each
• Shank type: 1/4" hex shank for quick‑change holders
• Material and finish: hardened steel with industrial surface treatment for wear resistance
• Compatibility: compatible with standard 1/4" bit holders and quick‑change chucks

How to use

Select the correct bit for the fastener head: PH2 for Phillips screws and the 1/4" security hex for tamper‑resistant hex fasteners. Insert the bit into a compatible 1/4" bit holder, quick‑change chuck or screwdriver. Ensure the bit seats fully to avoid slippage, apply steady axial pressure and operate the driver at appropriate speed and torque settings for the material and fastener size. Inspect the bit tip before use and replace if worn or damaged to maintain proper engagement and reduce risk of fastener damage.

Usage recommendations

For extended bit life, avoid excessive side loading and use torque‑controlled drivers when tightening small fasteners. Store the bits in a dry, tool‑organized case and replace any bit showing significant wear or deformation to ensure continued reliable performance.
