I don't know what you can say about 3/8" stainless steel bolts ? They arrived and they were correct, but in the end shorter than I needed, not the supplier's fault, mins ;)

Heck of a Hex Bolt

By Lambdog on October 7, 2011

Thread Size: 1/4"-28Thread Coverage: Partially ThreadedFastener Size: #10-12Number of Items: 5Overall Length: 3-1/4 Verified Purchase

My expectations for this Stainless Steel 316 Hex Bolt 1/4"-28 3-1/4" Length, were not high when I ordererd this product. I had spent about an hour searching the internets for a hex bolt with the propper threading. I had already visited those big named stores, but they did not carry the thread count in a long enough length. So when I came apon this gem on amazon, I had nothing to loose. The price was fair, so I took the plunge. I quivered at my front window waiting for the package to arrive for what seemed like an lifetime, but in all fairness the shipping time was fast if not regular. Apon recieving the Hex Bolts, I was astonished. They were high above my expectations of what a Hex Bolt could be. Briliant color, sharp lines, it mesmorized me. The engineer who thought up this baby must have been the offspring of a mortal and greek god. I had a hard time deciding to finally use them, they are like fancy art, but in the end my microwave had to be installed under the cabinet. Wrenching in those Hex Bolts was like sitting in a bean bag chair for the first time. Great product, would buy again.

Only last inch has thread

Not much to be critical of - it's a 4" stainless steel bolt. But only the last inch or so has threads.

You get what you pay for

The stainless bolts I bought apparently are all Chinese made. They tend to jam in the nuts when you tighten them. Might be wise to use Never-Seize when assembling. It hard to find decent hardware these days..
