    SAE J249 Square Neck Carriage Bolt

    SAE J249 grade 8(metric 10.9) black finish square neck dome head carriage bolt

    Carriage bolts are used to fasten wood to wood, wood to metal and metal to metal. They are a member of the round head bolt family and commonly have a "circular head with a low rounded top surface and flat bearing surface, and an integrally formed square neck under the head." Found on chain link fences and often on patio furniture and swing sets made of wood, carriage bolts are also known as: carriage screws, round head square neck bolts, coach bolts; shaker screen bolts (when fully threaded). Since the head is designed not to turn, they are usually tightened by torquing a nut. However, they can be used with an internally threaded (tapped) hole and tightened by turning the carriage bolt's square neck, if accessible.
    Threads are standard right-hand and Unified inch coarse series (UNC, Unified National Coarse). Lengths of 6" and shorter are usually fully threaded; lengths longer than 6" are partially threaded.
