| A carriage bolt, coach bolt or round head square neck bolt[1] is a form of bolt.It is distinguished from other Bolts by its head: the shank of the bolt is circular for most of its length, as usual, but the portion immediately beneath the head is formed into a square section.[2] This makes the bolt self-locking when placed through a square hole, or a round hole in most wood. This allows the fastener to be installed with only a single tool, a spanner or Wrench, working from one side. The head of a carriage bolt is usually a shallow dome. The squared section is of the same size as the diameter of the bolt shank, with a plain unthreaded shank | Standard: | DIN,ASTM/ANSI JIS EN ISO,AS,GB | | Material | Stainless Steel: SS201, SS303, SS304, SS316,SS316L,SS904L,F593 | | Steel Grade: DIN: Gr.4.6,4.8,5.6,5.8,8.8,10.9,12.9; SAE: Gr.2,5,8; ASTM: 307A,307B,A325,A394,A490,A449, | | Finishing | Zinc(Yellow,White,Blue,Black),Hop Dip Galvanized(HDG),Black Oxide,
