Carbon steel、Stainless steel、355 35K 45# 40Cr 35CrMo 42CrMo Name Hexagon Flange Bolts Standard ASME B 18.2.1 GB 5787 DIN 6921 Specification M5～M64 Size 1/4～4 Length 40mm～1500mm Grade 4.8 5.8 6.8 8.8 10.9 12.9 Material Carbon steel、Stainless steel、355 35K 45# 40Cr 35CrMo 42CrMo Surface black, zinc plated, color zinc, hot dipped galvanized, dacromet Scope of application The common bolt head is very thick, difficult to deformation, good after vibration, but also need to tighten; Flange with a thin part, can be slightly deformed, can lock more solid. There is if to the hole, ordinary bolts can not use tools, flange bolt head is small, the flange also plays a fastening role, but can use special tools to go to the hole, and hex bolts about the same principle. Again is the flange top flat pad to use, in the softer, non-wear-resistant material is safer, will not cause perforation Form a complete set of Hexagon flange bolt is a hexagon head and flange plate and screw together composed of fasteners.
