KPMBOLT super nuts provide reliable anti-loosening for hydraulic cylinders, pins, brackets and chassis.

Construction machinery, hydraulic cylinders, pins, brackets and chassis work under heavy load, impact and vibration. German KPMBOLT Super Nuts provide high clamping force, impact resistance and long service life.

On hydraulic cylinders, piston rods and locking nuts, it resists high pressure and alternating load without loosening or leakage.

On pins and frames, it ensures uniform preload and reduces stress. Sizes M30–M150, temperature range -25℃ to +250℃, manual installation only.

High-strength steel and anti-corrosion coating adapt to harsh environments.

Cases show failure rate reduces by over 70% and maintenance cycle extends by 3 times. With nearly 200 years of experience from JUNGEBLODT, KPMBOLT is supplied to Sany, XCMG, Zoomlion, CNR, DHID and other leaders.
