1"-8 × 5" مسامير رأس سداسي ثقيلة | صنع في الولايات المتحدة | فولاذ A307 درجة B مطلي بالزنك | خيط جزئي (30/عبوة)

Zinc plating looks even and uniform across all thirty, and the partial threads bite into the nut without any wobble once torqued down. Used them to bolt a jig frame together and not a single one stripped during install.

The partially threaded design made these perfect for my assembly jig where I needed a firm grip without the bolt bottoming out too soon. Zinc plating looks clean and should hold up fine in my shop environment.

Had to replace some bolts on a piece of equipment and these threaded in perfectly, the zinc coating looks like it'll hold up well. The partial threading is exactly what I needed for the application.
