Product Details

This product is a “basic necessity” for steel structure projects. It is an 8.8 grade medium-high strength fully threaded hex bolt, manufactured strictly according to German standard DIN933. It is suitable for non-core load-bearing connection scenarios such as steel structure secondary structures, accessories, railings, and ladders. In steel structure projects, 10.9S high-strength bolts are used for the main frame to ensure safety, while 8.8 grade bolts are used for the secondary structure to control costs. This product meets the strength standards, has stable quality, fully meets the load-bearing requirements of the secondary structure, and is also affordable. It is a basic category for bulk purchases by engineering companies and a frequently replenished item for trading companies. High-precision threads, easy installation, compatible with various steel structure accessories, complete stock specifications, and short delivery cycle.
