Screwdriver bit KS Tools 911.7854 — Hex metric, nickel, 25 mm, 1/4 inch hex shank (25.4×4 mm)

KS Tools 911.7854 is a 25 mm screwdriver bit with a metric hex tip designed for use in standard 1/4" (25.4×4 mm) hex shank holders. Manufactured from nickel-plated material and produced to DIN 3126 / ISO 1173 - C 6,3 dimensions, this compact bit is intended for precision fastening, maintenance and repair tasks that require a standardized, corrosion-resistant tip and reliable fit in power or manual drivers.

Advantages

The nickel plating provides enhanced surface protection against corrosion and wear while maintaining accurate tip geometry for consistent engagement with hex fasteners. Its 25 mm length offers a balance between access in confined spaces and control during hand or powered operation. Compatibility with 1/4" hex chucks and holders ensures interchangeability with common tool systems used in automotive, machinery and equipment servicing.

Suitable for

• Precision assembly and disassembly of metric hex fasteners
• Maintenance and repair work on machinery, electronics housings and panels
• Use with 1/4" hex bit holders, ratchet drivers and impact-compatible adapters (where appropriate)
• Tasks requiring compact bits for access in tight or recessed areas

How to use

Insert the 1/4" hex shank of the bit into a compatible bit holder, ratchet or power driver until it seats securely. Align the metric hex tip with the fastener and apply controlled torque appropriate to the fastener size and material. For hand-driven operations use steady pressure to avoid slipping; for powered use follow the tool manufacturer's torque and speed recommendations. Remove the bit by withdrawing it from the holder when the task is complete.

Recommendations

Inspect the bit tip before use for signs of rounding or damage and replace if worn. Use the nickel-plated bit in environments where mild corrosion resistance is required; avoid prolonged exposure to aggressive chemicals. Match torque settings to the fastener specification to prevent stripping.
