Hex Bolt for Pipeline & Structural Fastening

Hex Bolt for Pipeline & Structural Fastening is engineered specifically for fixed connection of industrial pipeline frames and building steel structures, produced in accordance with DIN933 international manufacturing standards. The base material adopts S45C medium carbon steel, with tensile strength reaching 800MPa after integral quenching & tempering heat treatment, meeting the load requirement of medium-heavy load fastening scenarios.

Core Technical Advantages

The surface of Hex Bolt for Pipeline & Structural Fastening chooses Dacromet anti-corrosion coating with finished coating thickness controlled at 6~12μm, neutral salt spray test lasts more than 500 hours without rust, adapting to coastal high humidity and chemical corrosive construction environments. Thread adopts full CNC precision rolling craft, thread tolerance follows 6g standard, the matching clearance is controlled within 0.03mm to avoid loosening under long-term alternating load.

Ningbo Gangtong Zheli Fasteners strictly implements full-process incoming inspection, semi-finished product detection and finished product sampling test, each batch of Hex Bolt for Pipeline & Structural Fastening will complete mechanical performance test before warehousing to stabilize product consistency.

Application Range & Specification Options

This series of bolts covers common specs from M10 to M36, custom length ranges 20mm~300mm, widely deployed in petrochemical pipeline fixing, photovoltaic support installation, factory steel beam connection and municipal infrastructure projects. Different surface options including hot-dip galvanized and black oxide can be customized based on clients’ environmental requirements.
