LINDSTROM Grade 5 Steel Square Neck Carriage Bolts

These carriage bolts are used for fastening metal to wood or metal in industrial assemblies, such as conveyor systems, machinery guards, and structural frames. The square neck prevents rotation during tightening, making them ideal for applications where a flush or low-profile head is required.

These bolts have a 3/8"-16 thread size, 1 1/4 in length, and are made from Grade 5 steel with a zinc-plated finish. They come in a 5-pack. The square neck design locks into place during installation, providing secure fastening in industrial settings.

Insert the bolt through a pre-drilled hole in the material, ensuring the square neck engages with the hole to prevent spinning. Tighten the nut from the opposite side using a wrench. For best results, use a washer under the nut to distribute load and avoid over-torquing, which can strip the threads.
