Bolt-3/4-10 X 6 1/2" UNC Grade 8

Bolt-3/4-10 X 6 1/2" UNC Grade 8

This 3/4"-10 x 6 1/2" Grade 8 hex bolt is engineered for high-stress fastening applications across various concrete mixer platforms, including McNeilus, Terex, and Con-Tech. Manufactured from quenched and tempered medium carbon alloy steel, it offers a minimum tensile strength of 150,000 PSI, making it ideal for mounting heavy components like gearboxes, drum pedestals, and hydraulic brackets. The coarse UNC thread ensures a secure grip and resists stripping under heavy vibration. Replacing worn or stretched bolts with Grade 8 hardware is essential for maintaining the structural integrity and safety of the mixer equipment.

Key Features

• Grade 8 medium carbon alloy steel construction for superior tensile strength (150,000 PSI minimum)

• 6.5-inch overall length suitable for deep structural mounting
• Hexagonal head designed for standard 1-1/8-inch wrenches or sockets
• High resistance to shearing and stretching under heavy mixer vibration
