Socket bit (6-point) EPM model E-400-1509 1/2" drive 9 mm long

EPM E-400-1509 is a 6-point socket bit with a 1/2" square drive and a 9 mm internal opening in a long version. It is designed to be used with ratchets and impact wrenches that accept a 1/2" drive, offering firm engagement with hex fasteners and extended reach for recessed or hard-to-access bolts and nuts. The long length improves accessibility in tight engine bays, machinery assemblies, and other confined workspaces where a standard-length socket would not reach.

Advantages

The 6-point profile reduces rounding of fastener corners by providing full contact on flats, while the 1/2" drive ensures compatibility with a wide range of ratchets and impact tools. The long design allows safer and more convenient work on recessed fasteners without the need to disassemble surrounding components. Manufactured to deliver stable torque transfer, the socket bit supports frequent workshop use and automotive repair tasks.

Suitable for

• Automotive repair and maintenance
• Mechanical assembly and disassembly
• Workshop general maintenance and service
• Accessing recessed or hard-to-reach hex fasteners

Key specifications

• Drive size: 1/2" square drive
• Internal size: 9 mm (6-point hex)
• Design: long version for extended reach
• Material and finish: suitable for workshop and automotive use (typical tool steel construction)

How to use

Select a ratchet or impact wrench with a 1/2" drive, attach the 9 mm 6-point socket bit securely to the tool, and engage the fastener ensuring full seating on the hex flats. Apply steady torque appropriate to the fastener specification and tool type. For impact wrench use, verify the socket and fastener are rated for impact applications and inspect the bit for wear before use. After use, store the socket bit in a tool tray or holder to prevent damage and ease future selection.

Usage recommendations

Use the socket bit for tasks requiring extended reach or when working with recessed hex fasteners. Match torque settings to fastener specifications, avoid excessive side loading, and replace the socket if rounding or significant wear appears to maintain safe and effective operation.
