Description
The HF-7048 Series U Bolt with Self-gripping Safety Nuts is a fastening solution designed with safety and stability in mind. It combines the classic U-bolt structure with a pair of vibration-resistant locking nuts, which provide additional security over traditional nuts, especially in environments where continuous movement or impact may cause loosening over time.
Self-gripping safety nuts feature internal mechanisms-such as nylon inserts or locking teeth-that engage the bolt threads with increased friction. This prevents unintentional loosening and eliminates the need for secondary locking components such as washers or lock nuts, saving installation time and reducing hardware complexity.
This U bolt set includes a rectangular steel backing plate that ensures force is distributed evenly across the mounting surface. This not only strengthens the connection but also helps avoid damage to the clamped material. The U-bolt's curvature is precision-formed, accommodating pipes, tubing, or rods while providing consistent pressure on both legs.
Available in sizes 8mm, 10mm, and 12mm, the HF-7048 series is especially useful in high-vibration settings such as marine railings, motor mounts, suspension systems, and industrial machinery. It ensures long-term fastening integrity even under thermal expansion, torque shift, or mechanical stress.
For professionals seeking added reliability without overcomplicating assembly, this product offers a balance of mechanical simplicity and operational safety.
FAQ
Q: Can I reuse the self-gripping nuts after disassembly?
A: While reusable, it is recommended to replace them after multiple uses to ensure optimal locking performance.
Q: What is the temperature tolerance of the safety nuts?
A: It depends on the locking mechanism used (e.g., nylon vs. metal teeth), but generally safe up to 120–150°C for nylon inserts.
Q: Does this product require washers?
A: No additional washers are needed, as the locking nuts and backing plate already ensure secure installation.
Q: Is the backing plate removable?
A: Yes, it is detachable and can be repositioned or replaced if necessary.
Q: What type of pipe can this be used with?
A: It is compatible with round pipes, conduit tubes, and even some square-profile rails, provided sizing matches.
