Frequently Asked Questions

What are Lindstrom carriage bolts used for?

Lindstrom Grade 5 steel square neck carriage bolts are used in wood-to-metal or metal-to-metal fastening where a smooth, rounded head is desired.

These Lindstrom carriage bolts have a 1/4"-20 thread size, 1 1/2 in length, Grade 5 steel construction, and a zinc-plated finish. They come in a pack of 10. The square neck design locks into place during installation, providing secure fastening without the need for a wrench on the head.
