Socket bit 1/4" hex 10 mm Hartsson 17A110Z

Hartsson 1/4" hex socket bit 10 mm (model 17A110Z) is a compact tool insert designed for use with 1/4" drive holders and bit sockets. It provides a precise 10 mm hex interface for fastening and loosening hex-head bolts and screws. The bit is suitable for manual ratchets, bit holders and compatible power drivers that accept 1/4" hex connections, making it a practical choice for light professional and DIY work in automotive, assembly and maintenance applications.

Advantages

The 10 mm hex profile delivers a secure fit on hex fasteners to reduce slipping and rounding. Its 1/4" shank is compatible with a wide range of bit holders and quick-change chucks, enabling fast tool changes and flexible use with both hand tools and powered drivers. The compact length and standardized hex geometry make it easy to access confined spaces while maintaining torque transfer efficiency. The bit is manufactured to provide consistent dimensions for repeatable fastening performance.

Suitable for

• Tightening and loosening 10 mm hex bolts and screws
• Automotive repairs and component assembly
• General maintenance tasks and equipment servicing
• Work with hand ratchets, bit sockets and 1/4" power drivers

Key specifications

• Drive size: 1/4" hex shank
• Bit tip: 10 mm hex
• Compatibility: fits standard 1/4" drive holders and quick-change chucks
• Application type: fastening and loosening hex-head fasteners
• Design: compact length for access in confined spaces

How to use

Insert the 1/4" hex shank of the bit into the appropriate bit holder, ratchet adapter or power driver chuck until it seats securely. Engage the 10 mm hex tip with the hex-head fastener and apply steady torque appropriate for the fastener size and material. Use controlled force to avoid over-torquing; for powered drivers, select a lower speed or torque setting when starting or working on delicate components. After use, remove the bit from the holder and store it in a dedicated bit case or rack to prevent damage and loss.

Usage recommendations

For consistent results, match the 10 mm hex bit to fasteners of the same size and inspect both bit and fastener for wear before use. When working on automotive or precision assemblies, use torque-controlled tools to achieve specified tightening values. Store the bit in a dry place to avoid corrosion and periodically check the tip for rounding or deformation.
