Carriage Bolt: 3/8-16, 1-1/2" Length Under Head, Square Neck MPN:215498MSC

DoALL's carriage bolt is designed for structural materials attachment on wood to steel or metal beams using a #36-16 thread type with an under head length of 1-1/2 and a square neck which adds extra strength as opposed to standard round neck varieties. Its sharp point allows fewer countersinks, hence accelerated assembly speed while a zinc plated finish provides resistance to rust in the long term for prolonged shelf life. These bolts can be employed with many construction, automotive and marine applications demanding strong bolts meeting industry standards of stringency.
