What are ASTM A320 L7 Bolts?
Bolts are devices that are utilized to efficiently connect different materials. ASTM A320 L7 Bolts are designed with a chemical composition of nickel, chromium, molybdenum, vanadium, and other alloys. The L7 bolts are intended for use in higher temperature bolting applications. These bolt have enhanced tolerance to corrosive and harsh media. The versatile a320 L7 bolt are available in a range of sizes and can be customized as per requirements.
The A320 bolt is designed in property classes A, B, C, and D. These bolt have excellent mechanical properties that set them apart from other bolt. The A320 L7 Hex Bolt are designed with a minimum tensile strength of 895mpa and a minimum yield strength of 585Mpa. The class D A320 L7 Heavy Hex Bolt have higher yield strength compared to the class A, B, and C class grades. The bolt have a Rockwell hardness of a minimum of 24 HRC. The A320 L7 Anchor Bolt can be elongated by a minimum of 15% and have a reduction area of 18%. To increase the hardness of the A320 L7 U Bolt, they can be heat-treated at temperatures of 1100 degrees F.

What does UNF stand for in threading of A320 L7 bolts?
The UNF threads ASTM A320 L7 carbon steel Bolt are of the Unified National Fine Thread. These threads have higher load capacity compared to UNC grades. The A320 Gr L7 Machine Bolt have lesser thread depth and smaller helix angles and better toughness. The threads are more conductive and have good self-locking capacity. The UNF SA 320 Gr L7 Eye Bolt can be easily assembled and later dissembled.

Are L7 bolts threads rolled or cut? How are rolled threads formed?
The threads on the ASTM A320 Grade L7 Carriage Bolt are generally thread rolled. These bolts can, however, in some cases be formed using cut threads. The process of roll threading SA 320 L7 Hex Cap Screws follows a cold forming process. Here hardened steel dies are used to form the threads onto the screws. The die protrudes into the outer diameter of the SA 320 Grade L7 Heavy Hex Head Bolt to create threads. As the bolt is under high pressure, the steel grain flows in multiple directions, causing it to be stronger. The rolled ASTM A320 Bolt are smoother for installation and resistant to damage when they are hardened or compressed.
