## Description

Product Description          Carriage Bolts are designed to fasten a wooden face to either a wood or metal frame. Its flat head is designed to eliminate the need for a washer and provide a semi-flush finish to applications. The square underside of the head is self locking to eliminate spinning and the need for a driving tool. The zinc plating is rust resistant and provides a beautiful, consistent finish; but, may not work for all exterior projects.             From the Manufacturer          Carriage Bolts have a smooth, rounded head that has a small square section underneath.

### ⭐⭐⭐⭐⭐ 







  
  
    Fantastic Price compared to local **** store.  Same Quality.
  

*by S***D on Reviewed in the United States on January 7, 2016*

Great bolts!  I have used a half dozen or so for projects and found no flaws in any of them. I am using them with t-nuts which I think are a little more prone to cross threading than regular nut and so far every one of them has threaded without any problems.  I bought a box of them so probably won't be buying any more for while but when I do and/or if I need a different size I will certainly look to Amazon and the Hillman Group to make that purchase.
