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. 

DIN912 Hex Socket Head Allen Bolt is a hexagonal head that allows for easy tightening and loosening, and is made from high-quality steel for maximum durability. With its sturdy construction and robust design, DIN912 Hex Socket Head Allen Bolt can withstand high levels of stress and strain, making it an ideal choice for heavy-duty applications. Made from high-quality steel, DIN912 Hex Socket Head Allen Bolt is resistant to corrosion and rust, ensuring reliable performance even in harsh environments. DIN912 Hex Socket Head Allen Bolt With its high strength, ease of use, versatility, and corrosion resistance, it is no wonder that it is a popular choice for a wide range of applications.

SABS 1282 Black Heavy Hex Bolts are specifically designed for use with heavy hex nuts in the connection of structural members (as opposed to tapped holes). SABS 1282 Black 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 SABS 1282 Black Heavy Hex Bolts are designed for strength and durability, allowing SABS 1282 Black Heavy Hex Bolts to conform to ASTM A325. SABS 1282 Black Heavy Hex Bolts are often applied alongside structural nuts and washers to metal beams and girders.
