Product Q&A

Q:What material is this carriage bolt made of?

It is made of medium carbon steel with a protective finish. Each shipment can include an EN 10204 3.1 material certificate, and third-party SGS/BV/TUV test reports are available on request.

Q:What standard does this carriage bolt comply with?

Manufactured strictly to DIN 603 / ASME B18.5 (round head square neck). Dimensionally interchangeable with premium European brands. Custom standards (ISO 8677, JIS B1184, ANSI B18.5) available for orders of 10,000 pcs or more.

Q:Why does a carriage bolt have a square neck?

The square neck under the round dome head seats into a square hole or locks into soft material, preventing the bolt from spinning while the nut is tightened - ideal for wood-to-metal and timber connections.
