Carriage Bolt: 3/8-16, 1-1/2" Length Under Head, Square Neck MPN:215499MSC

Carriage bolts have a square neck which offers more strength than standard round neck bolts and also prevents the nut from turning after being tightened, ensuring the bolt stays securely fastened in place. Its #36 thread diameter ensures compatibility with structural materials such as wood, steel or metals while an under head length of 1-1/2 provides additional support during load bearing activities. Furthermore, a sharp point enables easy penetration into material surfaces when assembling constructions while the zinc plated finish prevents rust and corrosion ensuring longevity in various environments where resistance to elements is paramount. The square neck adds extra tensile strength providing superior holding power that can resist shearing loads more effectively, hence making these bolts popular amongst construction and manufacturing industries where strong fastening methods are essential for durability.
