Socket bit 1/4" 5.5 mm Hartsson 6-point model 17A1055Z

Hartsson 6-point socket bit with a 1/4" drive and 5.5 mm size is a compact hexagonal socket designed for precision fastening in confined spaces. Suitable for use with ratchets, bit holders and compact driver sets, this socket bit provides a secure fit on 6-point fasteners found in appliances, interior automotive trim and light maintenance tasks. The short, robust profile helps transfer torque accurately while reducing the risk of rounding fastener heads.

Advantages

The 6-point geometry ensures full contact with fastener flats for improved grip and reduced cam-out. The 1/4" drive makes the bit compatible with a wide range of ratchets and bit adapters, while the 5.5 mm size covers common small fasteners used in household and vehicle applications. Durable construction offers resistance to wear under repeated use and maintains a precise fit for consistent torque transfer.

Suitable for

• Tightening and loosening 6-point bolts and nuts in household appliances
• Interior and trim fasteners in automotive repair
• General maintenance tasks in workshops and hobby projects

Key specifications

• Drive type: 1/4" (6.35 mm) square drive
• Socket size: 5.5 mm
• Point design: 6-point hex geometry
• Profile: Short/compact for access in confined areas
• Intended use: Manual ratchets, bit holders and driver sets

How to use

Attach the socket bit to a compatible 1/4" drive ratchet or bit holder by pushing it onto the square drive until it seats securely. Position the 6-point socket fully onto the fastener, ensuring even contact with the flats before applying torque. For tightening, turn steadily until the desired torque is reached; for loosening, apply controlled reverse rotation to avoid slipping. Inspect the bit regularly for wear and replace if rounding or deformation is visible.

Usage recommendations

Use with matching 6-point fasteners to minimize rounding; avoid using excessive impact tools unless the bit is explicitly rated for impact use. Store in a dry toolbox or bit organizer to prevent corrosion and keep the fit precise for future use.
