Grade 8.8 Carriage Coach Mushroom Head Square Neck Bolts M20 X 60 Mm HDG Treatment
1. Descriptions:
 
      Carriage bolts (round head with square neck) are commonly used in wood connections. The square neck under the round head will seat into the hole in the wood to prevent the head from turning. Because they are used with wood, carriage bolts are rarely high strength and virtually always supplied in a standard ASTM A307 specification
 
       Carriage bolts are designed to fasten a wooden face to either a wooden or metal frame during general construction applications. This carriage bolt features a smooth, rounded head for appearance, safety and security. The galvanized finish provides optimal rust prevention against outdoor elements. Recommended for exterior use. The length for carriage bolts is measured from under the head to the end of the bolt, including the square neck.

  • The hot-dipped galvanized coating is designed for use in highly corrosive environments such as coastal areas or heavily polluted atmospheres
  • Common applications include deck and fencing construction as well as outdoor furniture
  • The square underside of the head is self-locking, eliminating the need for a driving tool and prevents the bolt from rotating when tightening nuts
  • Only use galvanized coated nuts and washers with galvanized bolts
  • Conforms to ASTM A153 specifications
  • A carriage bolt, also known as a coach bolt, has a domed or countersunk head, and the shank is topped by a short square section under the head.
  • The square section grips into the part being fixed (typically wood), preventing the bolt from turning when the nut is tightened.
