HEAVY HEX ROT MILL BOLT

Mill Rotating Screw — Heavy-Duty Fasteners for Grinding Mills

Our mill rotating screws (also known as rot mill bolts) are precision-engineered fasteners designed for use in SAG mills, ball mills, and other heavy-duty grinding equipment. These screws play a critical role in securing liners, shells, and mill components that endure continuous rotation, heavy vibration, and extreme stress in mining, aggregate, and mineral processing operations.

Manufactured from high-strength alloy steel and often featuring heavy hex heads, these rotating screws offer superior fatigue resistance to ensure reliable mill performance. Their robust design meets or exceeds industry specifications, making them ideal replacements or upgrade parts for your milling equipment.

Key Features:

  • Engineered for high fatigue and wear resistance

  • Heavy hex head design for easy installation and removal

  • Made from durable alloy steel

  • Compatible with various SAG and ball mill models

  • Essential for maintaining mill stability and operational safety
