Reviewing the bolts I bought, I'd like to see the length of threads or the length of un-threaded portion of the bolt shaft listed alongside other bolt specs on the website, but otherwise, these are exactly what I was hoping for. Great products, great company. Second time purchasing through them. Tough to find square-headed bolts affordably these days, especially in quantities available here. The products I bought also arrived sorted into a handy section-sealed plastic roll, with sections labeled individually for easy identification. These folks go the extra mile.
