Product Features & Applications
Product Description The equal‑strength damping nut features a hexagonal body, a sealed top cap, and a one‑piece mushroom base. Manufactured from materials with strength matching that of the bolt rod, this single‑cap damping design eliminates the need for a secondary nut, making it compatible with all types of mining roof‑bolt support systems.
Advantages
-
Damping cap instead of double nuts – boosts drivage efficiency: The top damping structure ensures self-locking and vibration resistance, eliminating the auxiliary nut and simplifying site assembly, thus reducing bolting time and speeding up roadway development.
-
Equal-strength material – adequate anchoring capacity: With mechanical properties matching the bolt, the nut resists stripping and thread damage, fully utilizing the bolt's tensile strength for higher support reliability.
-
One-piece mushroom base – improved load distribution: The enlarged base increases contact with the bearing plate, evenly dispersing pre-tension forces and preventing plate crush or collapse.
