Avery V. ★★★★★

Had to bolt down a piece of shop equipment and these B7s torqued up without any thread galling, even with the partial thread engaging clean. The 3-1/2" length gave me just enough bite for the heavy flange I was wrestling with. Solid pack for the price, no doubt I'll grab another box when I run low.

Michael K. ★★★★★

The threading cut clean on my first pass, and the partially threaded length gave me plenty of grip for a heavy flange joint. These B7s have that solid, dense feel you want on critical machinery.

Benjamin S. ★★★★★

Installing these on a pump skid and the partially threaded portion made alignment much easier than fully threaded bolts would have. The 3-1/2 inch length was exactly what I needed for a flange connection.
