Product Information

Full details

The Facom Impact Socket (NKD.34L) is designed for professional mechanics and industrial technicians who require high-torque performance and durability from their tools. Featuring a robust 3/4-inch drive and a precise 34mm 12-point bi-hexagon profile, this socket delivers exceptional grip and power transfer during heavy-duty fastening tasks. The primary caveat is that it is strictly intended for use with high-torque impact tools and is not optimized for light-duty manual applications where a standard six-point socket might be preferred to avoid rounding fasteners.

FAQs

Can I use this socket with a hand-operated ratchet?

While it is physically possible if you have a 3/4-inch drive ratchet, this socket is optimized for impact tools and may be heavier than necessary for manual work.

Is the 12-point design safe for high-torque applications?

Yes, Facom impact sockets are engineered to handle high-torque applications; however, for extremely seized fasteners, ensure the socket is seated perfectly straight to avoid rounding.

Does the finish peel over time?

The manganese phosphate finish is a chemical conversion coating, not a paint, so it is designed to wear down slowly without flaking or peeling.

Is this socket compatible with air guns and electric impact wrenches?

Yes, it is compatible with both pneumatic and electric impact tools that utilize a 3/4-inch square drive.

What does the 34mm size refer to?

It refers to the width across the flats of the fastener the socket is intended to drive.

Troubleshooting

Socket feels loose on the fastener

Verify that the fastener is indeed a 34mm metric bolt; ensure there is no buildup of debris or rust inside the socket.

Socket keeps slipping off the impact wrench

Check the drive interface for wear; ensure the retaining pin or ring on your impact wrench is functioning correctly.

Pros and Cons

Pros

  • Extremely durable construction for industrial use
  • Corrosion-resistant manganese phosphate coating
  • Precise 12-point fit reduces fastener damage
  • Optimized for high-torque impact wrenches

Cons

  • Limited to 3/4-inch drive systems
  • 12-point design can be more prone to rounding on extremely seized bolts than 6-point sockets
  • Heavyweight profile not suitable for compact kits

Setup, Compatibility & Care

To ensure the longevity of your Facom impact socket, always pair it with a compatible 3/4-inch drive impact wrench or extension bar. Avoid using this socket with chrome-vanadium manual extensions or ratchets, as they may shatter under impact stress.

Maintenance Tips:

  1. Cleaning: Wipe the socket with a dry cloth after use to remove grease and metal filings.
  2. Storage: Store in a dry place to maintain the integrity of the manganese phosphate finish. If working in extremely wet conditions, apply a light coat of machine oil.
  3. Inspection: Regularly inspect the inner teeth of the 12-point profile for signs of metal fatigue or warping; if the teeth are deformed, the socket should be replaced to prevent damaging your fasteners.
