Socket bit 1/4" 6-point 12 mm Hartsson 17A112Z

Hartsson 1/4" 6-point 12 mm socket bit (model 17A112Z) is a compact socket designed for use with 1/4-inch drive ratchets, T‑handles and bit holders. The 6-point profile fits hexagonal fasteners to reduce rounding and provide positive engagement on bolts and nuts. Its 12 mm size and short, robust construction make it suitable for tight spaces and general mechanical, automotive and assembly work where controlled torque and a slim tool profile are required.

Advantages

The six-point geometry concentrates contact on the flats of fasteners to minimize slipping and rounding. Its 1/4" drive interface ensures compatibility with common ratchets and bit adapters, while the compact length aids access in confined areas. Manufactured for durability, the socket bit resists wear during repeated tightening and loosening operations and provides consistent fit and retention on standard 12 mm hex fasteners.

Suitable for

• Light and medium automotive repairs where a 12 mm hex socket is needed
• General mechanical maintenance and assembly tasks
• Work with 1/4" drive ratchets, T‑handles, and bit holders in confined spaces
• DIY projects requiring precise engagement on hex bolts and nuts

Key specifications

• Drive size: 1/4" (compatible with standard 1/4" ratchets and bit adapters)
• Socket profile: 6-point (hexagonal)
• Nominal size: 12 mm
• Construction: short/compact socket bit for improved access
• Typical applications: tightening and loosening hex bolts and nuts

How to use

Select the 12 mm Hartsson 6-point socket bit and attach it securely to a 1/4" drive ratchet, T‑handle or bit holder. Position the socket squarely onto the hex fastener, applying steady rotational force while keeping axial alignment to avoid rounding the fastener. For assembly tasks, use controlled torque appropriate to the fastener specifications. Remove the socket bit by pulling it off the adapter or ratchet after completing the operation and inspect for wear before further use.

Usage recommendations

Use hand tools and torque-limiting devices where required; avoid excessive impact or over-torquing with air or electric impact tools unless the socket is rated for such use. Store the socket bit in a dedicated organizer or bit holder to retain its shape and ensure fast access.
