ASTM A194 Grade 7 Nuts

ASTM A194 Grade 7 Nuts are heavy strength, internally threaded fasteners manufactured for use in high-pressure and high-temperature service where there is a need for more strength than the standard Grade 2H provides. While the term ASTM A194 GR.7 Fasteners is used in the market, please be aware that this specification applies only to nuts.

The main difference between Grade 7 and other common grades is the material. Grade 2H is made with carbon steel; however, A194 Gr.7 nuts are made with a higher grade alloy steel, more specifically AISI 4140/4142 type alloy steel, which is a chromium-molybdenum (chrome-moly) alloy. The combination of the alloy and the requirement for a Q&T (Quench and Temper) heat treatment, provides the A194 7 Nuts with strength and hardness at higher temperatures. Due to the higher loads, these ASTM A194 gr 7 nuts would almost exclusively be supplied as heavy hex nuts for larger bearing surface and higher stripping resistance.
