ASTM A194 Grade 6 Hexagonal nuts, manufactured from low-carbon steel and normalized, are fasteners that offer reliable connections at low temperatures with moderate mechanical strength. They are particularly preferred in applications where low-temperature and impact resistance are important. They are commonly used in pressure vessels, piping systems, and valve connections.

Grade 6 nuts are made from low-carbon steel and normalized. At temperatures as low as -50 °C Suitable for use. Provides a secure connection in environments requiring impact resistance.
Grade 6 nuts, low-temperature applications Grade 2H nuts are preferred for applications requiring high strength and higher hardness. Grade 6 has lower hardness and is normalized.
Grade 6 nuts, typically flange connections requiring medium strength, Pressure equipment installations and in statically loaded pile applications is used. Thanks to its normalized structure, it is used in both production and assembly processes. suitable workability and post-source stability provides. In this regard, industrial piping systems stand out as a safe connection element in boiler connections and compressor lines.
