Product Information
Full details
The Facom NSD.27B is a professional-grade 27mm impact socket designed for mechanics and industrial technicians who require high torque reliability on heavy-duty machinery, trucks, and agricultural equipment. Its primary strength lies in its 12-point bi-hexagonal design and robust steel construction, which minimizes the risk of fastener rounding during intense impact applications. While it is an exceptional tool for demanding environments, users should note that its 1/2-inch square drive is specific to heavy-duty impact wrenches and may be oversized for standard automotive repair tasks.

FAQs
Is this socket compatible with standard hand ratchets?
Yes, it is compatible with any 1/2-inch drive hand tool, though it is specifically hardened for impact use.
Can I use this on 6-point bolts?
Yes, the 12-point design is compatible with 6-point bolts, though 6-point sockets are generally preferred for extremely high-torque applications to minimize fastener wear.
Does the phosphate finish require special cleaning?
No, simply wipe it with a clean rag. Avoid using abrasive steel brushes as they can strip the protective finish.
What is the primary material used?
The NSD.27B is forged from high-strength alloy steel engineered for impact resilience.
Is this safe to use with a torque wrench?
Yes, you can use this socket with a torque wrench, but ensure you account for any extension or socket mass if performing critical calibration work.
Troubleshooting
Socket fits loosely on the fastener
Verify the fastener size is exactly 27mm and check for heavy debris or paint buildup on the bolt head.
Socket keeps falling off the impact wrench
Check the condition of the detent ball on your impact wrench anvil and ensure the retaining ring on the socket is intact.
Pros and Cons
Pros
- High torque capacity for heavy machinery
- Durable phosphate finish prevents rust
- 12-point design allows for easier fastener engagement
- Compact 46mm length fits into tight clearance areas on heavy equipment
Cons
- Not suitable for standard 3/8-inch drive tools
- 12-point profile can cause rounding on extremely soft or rusted bolt heads compared to 6-point sockets
- Heavier than standard chrome hand-tool sockets
Setup, Compatibility & Care
To ensure peak performance, verify your impact wrench has a compatible 1/2-inch square drive output. Always use an impact-rated retaining ring or pin if your wrench is equipped with a locking mechanism to prevent the socket from detaching during operation. For maintenance, wipe the socket clean of grease and debris after use. While the phosphate finish is highly durable, storing the tool in a dry environment will further prevent surface oxidation. Avoid using this socket with chrome-plated hand tools, as the material hardness of impact sockets can potentially cause failure in non-impact-rated accessories.
