KS Tools 911.5123 screwdriver bit

The KS Tools 911.5123 screwdriver bit is a Pozidriv bit designed for precise fastening tasks. Manufactured from durable nickel material, this 30 mm bit combines compact size and reliable strength to work with compatible drivers that accept a 5/16" (127/16 mm) hexagonal shank. Weighing approximately 10 g, it is intended for repeatable engagement with Pozidriv screws where a secure fit and controlled torque transfer are required.

Advantages

The nickel construction provides corrosion resistance and maintains dimensional stability under normal workshop conditions. The Pozidriv profile ensures reduced cam-out compared with plain Phillips profiles, delivering improved engagement with compatible screw heads. Its compact 30 mm length makes it convenient for use in tighter spaces while the hexagonal shank size promotes positive retention in quick-change chucks and bit holders.

Suitable for

• Precision assembly and small appliance repair
• Electronic housings and light mechanical fastening
• Maintenance tasks requiring Pozidriv screwdrivers or bit holders

Key specifications

• Tip type: Pozidriv
• Material: nickel-plated steel
• Length: 30 mm
• Weight: approximately 10 g
• Shank type: hexagonal
• Shank size: 5/16" (hex)

How to use

Insert the hexagonal shank into a compatible screwdriver, bit holder, or quick-change chuck until it seats securely. Align the Pozidriv tip with the corresponding screw head and apply steady axial pressure while turning the driver to avoid slippage. For removal, reverse the rotation while maintaining alignment. Inspect the tip for wear and replace the bit when rounding or deformation of the tip occurs to preserve screw head integrity.

Recommendations

Use the bit with drivers or holders that match the specified hex shank size to ensure secure retention. Avoid excessive torque beyond the bit’s capability and select the correct Pozidriv size to minimize damage to both bit and screw. Store the bit in a dry environment to reduce corrosion despite the nickel plating.
