Quantity
ASTM A453 Gr.660 Fastener is crafted from high-performance A286 material, compliant with ASTM A453 Gr.660 A standards, and designed for extreme low-temperature environments. With a size of M42 and a length of 440mm, it features ISO 261 threads and is paired with ISO 4033 heavy hex nuts to ensure a secure connection. Having passed -196°C impact tests, its low-temperature toughness and impact resistance are guaranteed, making it suitable for applications in liquefied natural gas (LNG), cryogenic equipment, and ultra-low-temperature industrial fields. With its reliability and durability, ASTM A453 Gr.660 Fastener has become an indispensable component in frigid environments.
