Product Information

Full details

The Facom 75.5/16 is a professional-grade angled open socket wrench engineered for mechanics and technicians who require high-torque performance in confined spaces. Its unique design features a 6-point head and a tubular handle that provides superior leverage for unlocking stubborn fasteners, making it an essential tool for automotive and industrial maintenance. While it offers exceptional durability and access for threaded rods, users should note that its specialized design is optimized for specific 5/16 inch (12.5 mm) fasteners, limiting its versatility for general-purpose metric-only toolkits.

Extended Product Information

FAQs

Is this tool suitable for metric bolts?

This tool is sized for 5/16 inch fasteners, which corresponds to 12.5 mm. It is intended for specific imperial-sized hardware.

Can I use an extension bar for more leverage?

The wrench is designed for manual use. Adding an external cheater bar or extension may exceed the rated torque limits of the tool and is not recommended.

Why is the head open?

The open-head design allows the wrench to pass over threaded rods, providing reach that standard closed-socket wrenches cannot achieve.

How do I prevent the chrome finish from peeling?

Avoid using the wrench as a hammer and keep it away from harsh acidic cleaners. Regular wiping with a clean cloth keeps it in top condition.

What is the weight of this tool?

The Facom 75.5/16 weighs approximately 60 grams.

Does the 5-degree offset help with clearance?

Yes, the offset is specifically designed to lift the handle away from the work surface, providing enough room for your hand during operation.

Troubleshooting

Wrench slipping on the fastener

Ensure the wrench is fully seated on the nut and that the nut size is exactly 5/16 inch; check for rounded corners on the fastener.

Difficult to access the nut in deep spaces

Verify that there is sufficient clearance for the handle offset; if the handle hits an obstruction, try rotating the wrench 180 degrees to change the orientation.

Pros and Cons

Pros

  • Excellent for accessing nuts on long threaded rods
  • Provides high leverage for unlocking tight fasteners
  • Durable satin chrome finish resists corrosion
  • Lightweight construction for easier handling
  • High-quality chrome alloy steel provides long life

Cons

  • Specific 5/16 inch size limits multi-purpose utility
  • Not suitable for fasteners outside the 12.5mm/5/16" range
  • Requires enough clearance for the handle offset

Setup, Compatibility & Care

To ensure the longevity of your Facom 75.5/16 wrench, verify the fastener size is exactly 5/16 inch (12.5 mm) before application. Using the tool on incorrectly sized fasteners can cause rounding of the nut corners.

Care Instructions:

  • Cleaning: Wipe the tool with a dry, clean cloth after each use to remove oil, grease, and metal shavings.
  • Storage: Store in a dry toolbox or on a wall rack to prevent environmental moisture exposure.
  • Inspection: Periodically inspect the 6-point inner walls for signs of metal fatigue or excessive wear.
  • Maintenance: Apply a light coat of machine oil if the tool will be stored for extended periods in humid climates.
