  • Nice Looking High Quality Carriage Bolts
Size: 1/4-20 x 1-1/4" (10 Sets)
Needed these carriage bolts + hex nuts for my renovation project for my deteriorating side gate. Couldn't find the right length ones at the local hardware stores. Was so happy to find these on Amazon. Not only they are the right size and fit but they are also high quality and good looking. Added the nice look to the finished project (see before and after pictures). Since they are made of stainless steel they should last me a long time and not all rust up like the old ones. ... show more

I opened the box and, oops; closed it back up and sent it back, immediately ordered 2 more boxes of the correct size. This is very nice looking hardware. It took forever to get here, both times; I am still waiting for the refund on the return, 29 days so far...
