Product Information
Full details
The Facom 1/2 inch drive deep thin-wall impact socket (NSB.21) is designed for professional mechanics and automotive technicians who require high-torque performance in restricted spaces. This 21mm socket offers a significant advantage in accessing recessed lug nuts and confined bolts, though users should be aware that the thin-wall profile is intended specifically for impact wrench use with compatible safety accessories to maintain structural integrity.

FAQs
Can I use this socket with a standard hand ratchet?
Yes, it is compatible with any 1/2 inch drive tool, but it is optimized for the power and vibration of impact wrenches.
Is the thin-wall design safe for high torque?
Yes, it is specifically engineered from high-strength alloy steel to handle impact torque while maintaining a thin profile.
What does the 6-point convex design do?
It shifts pressure from the corners of the bolt to the flats, reducing the likelihood of rounding off the fastener.
Does it need a specific pin and ring?
Yes, for safety during high-torque operation, you must use compatible rings and pins to prevent the socket from detaching from the wrench.
Is this socket suitable for non-impact use?
While it can be used for manual tasks, it is built specifically to withstand the rigors of impact wrench use.
How do I prevent rust on the black phosphate finish?
Keep the tool clean and dry after use, and apply a light machine oil wipe-down if stored in a humid environment.
Troubleshooting
Socket feels loose on the fastener
Verify that you are using exactly the 21mm size and that there is no debris or corrosion inside the socket hex profile.
Difficulty attaching to impact wrench
Ensure the locking ring and pin alignment are clear of obstruction and that the square drive of the tool is free of burrs.
Pros and Cons
Pros
- Excellent access for recessed fastener locations
- Reduces risk of rounding fastener corners
- High corrosion resistance for long service life
- Optimized for high-torque applications
Cons
- Requires specific safety pins and rings for secure impact use
- Thin-wall design is more susceptible to cracking if used with non-impact equipment or extreme overload
- Limited to 21mm size fasteners
Setup, Compatibility & Care
To ensure safety and performance, always secure the socket to your impact wrench using the recommended locking rings and pins. The socket is designed for 1/2 inch square drives. After use in wet or greasy conditions, wipe the socket clean with a dry cloth. Although the black phosphate finish is corrosion-resistant, it is a good practice to apply a light coat of machine oil periodically to keep the surface conditioned. Do not use this socket with non-impact grade adapters, as the torque transfer may cause them to shear.
