Product Information

Full details

The Facom R.3/8E is a high-performance, professional-grade 1/4" square drive socket designed for mechanics and technicians who require precision and durability in tight fastening applications. Featuring Facom's proprietary OGV profile and a 12-point design, this tool excels at delivering consistent torque without damaging fastener corners; however, users should note that as a standard socket, it lacks the deep-reach capabilities required for specific automotive engine components.

FAQs

Is this socket compatible with impact drivers?

No, this socket is designed for manual hand-tool use and may fail if used with power impact drivers.

What does OGV stand for?

OGV is Facom's proprietary profile design that moves the contact point from the fastener corners to the faces, reducing wear.

What is the total length of the R.3/8E?

The socket has an overall length of 22 mm.

Does this have a warranty?

Facom tools generally come with a lifetime warranty against manufacturing and material defects under normal use conditions.

Can I use this for metric fasteners?

No, the R.3/8E is sized specifically for 3/8" AF (Across Flats) Imperial fasteners.

Troubleshooting

Socket does not fit on the fastener

Verify that the fastener is indeed a 3/8" AF size and ensure no debris or rust is blocking the socket's internal cavity.

Socket slips under load

Ensure the socket is pushed completely flush against the bolt head. If the bolt is already damaged, consider using a 6-point socket instead.

Pros and Cons

Pros

  • Prevents fastener rounding via OGV profile technology
  • Compact size allows access in extremely tight spaces
  • High-quality material construction ensures long-term durability
  • 12-point design increases indexing options on nuts and bolts

Cons

  • Not suitable for high-clearance fasteners due to standard 22mm length
  • 12-point design can risk slipping on extremely rounded or damaged bolt heads compared to 6-point alternatives
  • Limited to 1/4-inch drive systems

Setup, Compatibility & Care

This socket is compatible with any standard 1/4" square drive handle, breaker bar, or torque wrench. To ensure longevity, always seat the socket fully onto the fastener before applying force. After use in greasy or dirty environments, wipe the socket with a clean rag to remove debris. While the finish is corrosion-resistant, storing the socket in a dry tool chest or drawer will prevent oxidation over time. Do not use this 1/4" socket with high-torque impact guns, as it is designed for manual hand-tool application.
