Stainless Steel 304 Carriage Bolt With Square Neck | GB/T12-1976 DIN 603 Standard Carriage Bolts

Stainless steel carriage bolts, also known as stainless steel square neck bolts, are a type of fastener compliant with GB12, GB14, GB801, and DIN603 standards. These standards cover different head designs, such as small button head (GB12), large button head (GB14, DIN603), and low square neck (GB801), which should be selected according to practical application requirements. This type of bolt is primarily used in marble installation with dry-hanging fixtures. Its square neck structure prevents the bolt shaft from rotating during tightening, facilitating secure and efficient construction.
