Product Details
Lock Nut
Jinmao brand U-shaped lock nut
The U-shaped structure anti loosening principal technology has obtained a national invention patent with patent number ZL 2021 1 0487670.0.
We transfer the position of the vibration force by changing the structure of the nut, transmitting the vibration force to the top of the nut, forming a centripetal tightening force, achieving the best anti loosening effect, and creatively achieving:
One nut can prevent loosening
Repeated installation and never loosening
The vibration stronger, the grip tighter

-
Vibration-Proof Locking
The U-shaped bridge deforms elastically when tightened, creating a constant prevailing torque that prevents loosening under shock or vibration. -
Material Excellence
Manufactured from AISI 304/316 stainless steel, ensuring superior corrosion resistance for marine, chemical, and outdoor environments. -
Reusable & Tool-Free
Unlike nylon-insert lock nuts, the all-metal design withstands repeated assembly/disassembly without loss of locking performance. -
Jinmao Brand Assurance
Produced in ISO 9001-certified facilities with full batch traceability and 100% thread gauging; each nut is laser-marked with the Jinmao logo for authenticity. -
Wide Temperature Range
Performs from -80 °C to +300 °C, making it ideal for high-heat exhaust systems or cryogenic piping.
