Mining equipment operates in highly abrasive, dust-filled, and impact-heavy environments. Standard fasteners will shear or strip quickly. SRG Fasteners produces ultra-high-tensile bolts (Grade 10.9 and 12.9) for rock crushers, ball mills, and conveyor systems.
Our mining fasteners feature specialized anti-galling coatings and are designed for rapid field maintenance under difficult conditions.
Frequently Asked Questions
