ANSI A490 Balck Heavy Hex Bolts are specifically designed for use with heavy hex nuts in the connection of structural members (as opposed to tapped holes). ANSI A490 Balck Heavy Hex Bolts are strong heavy-duty bolts that are typically used for creating structures through steel to steel structural connections such as buildings and bridges. A grade 8 bolt would be one that meets ASTM A490 standards. The high quality steel used to create ANSI A490 Balck Heavy Hex Bolts are designed for strength and durability, allowing ANSI A490 Balck Heavy Hex Bolts to conform to ASTM A325. ANSI A490 Balck Heavy Hex Bolts are often applied alongside structural nuts and washers to metal beams and girders.

DIN127A Lock Single Coil Spring Washer are commonly used metric lock washers, As you tighten a bolt, these DIN127A Lock Single Coil Spring Washer flatten to add tension to the threaded joint and prevent loosening from small amounts of vibration. DIN127A Lock Single Coil Spring Washer meet a DIN or ASME standard for split lock washer dimensions. Standard DIN127A Lock Single Coil Spring Washer have a left-hand helix, which means you can only use them with bolts that have right-hand threads to prevent clockwise rotation from vibration. 

ASTM A307 Grade B Carbon Steel Threaded Rod , also known as a stud, is a relatively long rod that is threaded on both ends; A threaded rod in bar stock form is often called all-thread (ATR); other names include fully-threaded rod, redi-threaded rod, continuously-threaded rod, and TFL rod.

DIN931 Hex Bolt is the most commonly used hex bolt in the metric bolt, DIN931 Hex Bolt common grades are 4.8, 6.8, 8.8, 10.9, 12.9. DIN931 Hex Bolt surface is coated with different coatings for different environments.
