Product Information

Full details

The Facom 1/2-inch Drive Hexagon Bit Socket Set (STM.J9APB) is an essential toolkit designed for professional mechanics and industrial technicians who require precision and durability in heavy-duty fastening tasks. This 9-piece set provides a comprehensive range of sizes from 5mm to 19mm, offering high torque capabilities and a reliable grip on hexagonal fasteners. While the set is built for extreme performance, users should note that the bits are non-removable, meaning the socket and bit function as a single integrated unit rather than interchangeable components.

Extended Product Information

FAQs

Are these bits replaceable if they break?

No, these sockets feature non-removable bits designed for maximum stability; if a tip is damaged, the specific socket unit must be replaced.

Can I use these with an impact wrench?

While these are robust tools, they are primarily designed for manual drive. Using them with high-torque impact guns may void the warranty or accelerate wear.

What sizes are included in the set?

The set includes 5, 6, 7, 8, 10, 12, 14, 17, and 19mm sizes.

Is the case included with the purchase?

Yes, the set is delivered in an empty BP.MBOXS case designed specifically to store these 9 pieces.

What is the benefit of the phosphate-hardened tip?

The phosphate treatment provides a harder, more resilient surface on the tip that resists deformation and helps maintain a secure grip inside the fastener.

Are the sizes marked clearly?

Yes, each socket is laser-etched with the size for easy identification even in low-light conditions.

Troubleshooting

Socket is difficult to remove from the ratchet

Check if the detent ball is stuck or if there is excessive debris inside the square drive hole; clean and apply a thin layer of lubricant.

Bit is slipping inside the bolt head

Verify the bolt size matches the socket exactly; if the bolt head is already rounded, use a bolt extractor instead.

Surface rust appearing on the tip

Use a light abrasive pad to remove surface rust and apply a thin coat of machine oil or anti-corrosion spray before storing.

Pros and Cons

Pros

  • High-durability construction suitable for demanding professional use
  • Phosphate-hardened tips resist stripping and rounding
  • Professional bright chrome finish prevents rust and is easy to clean
  • Integrated bit design increases stability and reliability under load
  • Includes a robust storage case for workspace organization

Cons

  • Non-removable bits mean the entire socket must be replaced if a single tip is damaged
  • Lacks smaller sub-5mm sizes for electronics or fine mechanical work
  • Requires a compatible 1/2-inch drive tool for operation

Setup, Compatibility & Care

To begin, ensure your existing ratchet or torque wrench is a standard 1/2-inch square drive. Simply attach the desired socket size until the detent ball on your ratchet clicks into the socket's locking hole.

Compatibility: This set is fully compatible with any standard 1/2-inch drive manual ratchet, breaker bar, or click-type torque wrench.

Care Instructions:

  • Wipe the sockets with a clean, dry cloth after each use to remove oil, grease, and metal shavings.
  • Store the sockets in their original BP.MBOXS case to prevent moisture buildup and surface oxidation.
  • Avoid using these sockets with pneumatic impact guns unless the tool is specifically rated for impact use, as repeated extreme shock can reduce the lifespan of the bit tips.
