Ruuvauskärki KS Tools 910.2259 Hex ruostumaton teräs 25 mm

The KS Tools 910.2259 Hex Stainless Steel 25mm screwdriver bit is a compact, precision bit designed for use with hex-compatible drivers and bit holders. Manufactured from stainless steel and machined to a hexagonal shank profile, this 25 mm long bit offers corrosion resistance and dimensional stability for repetitive fastening tasks. It is produced to conform with DIN 3126 and ISO 1173 - C 6,3 standards, ensuring compatibility with common bit holders and drivers that accept C 6,3 (1/4") hex shanks.

Advantages

The stainless steel construction provides increased resistance to rust and surface wear compared with standard carbon steel bits, while the hex shank ensures secure fitting in magnetic or mechanical bit holders. Its 25 mm length balances reach and control for precision work, and the light weight supports comfortable handling during extended use. Compliance with recognized DIN and ISO standards promotes interchangeability and predictable fit in customary tool systems.

Suitable for

• Assembly and disassembly of small to medium fasteners using hex-compatible drivers
• Precision electronics and appliance servicing where compact bit length is required
• Maintenance tasks in environments where corrosion resistance is important
• Use with bit holders, quick-change chucks and compact driver tools

Key specifications

• Material: stainless steel
• Shank profile: hexagonal (C 6,3 / 1/4")
• Overall length: 25 mm
• Weight: approximately 4 g
• Standards: manufactured to DIN 3126 and ISO 1173 - C 6,3 dimensional specifications

How to use

Select a compatible hex bit holder or driver that accepts a C 6,3 (1/4") shank, insert the KS Tools hex bit fully into the holder until it seats securely, and engage the driver. Apply steady axial pressure and appropriate torque for the fastener being driven, avoiding excessive lateral force that could deform the bit tip. After use, store the bit in a dry tool case or rack to maintain its corrosion-resistant surface.

Recommendations

For long service life, avoid using the stainless steel bit at torque levels intended for hardened tool steel bits. Match the bit length and type to the fastener and workspace to prevent slippage and rounding. Use appropriate personal protective equipment when working with power drivers.
