Overview

This Grade 8.8 carbon steel hex bolt is engineered for high-strength structural connections in commercial construction, heavy machinery assembly, and industrial fabrication. Its square head design provides superior wrenching capability in tight or recessed spaces where a standard hexagonal head may not fit. The partial thread configuration ensures maximum thread engagement in tapped holes while leaving a smooth shank section to bear shear loads, making it an ideal choice for pivot points and structural joints.

Key Features

Manufactured from medium carbon steel for a tensile strength of 116,000 PSI Black oxide finish provides a durable, corrosion-resistant surface Square head measures 1.38 inches for secure tool engagement Partial thread design optimizes clamping force and shear resistance Fully meets ISO 898-1 and DIN 933 specifications for Grade 8.8 performance
