براغي سداسية ثقيلة 3/4-10 × 3" | صنع في الولايات المتحدة | فولاذ A307 درجة B غير مطلي | ملولبة جزئيًا (40/عبوة)

The partial threading on these made quick work of aligning my industrial shelving supports without bottoming out. The A307 steel feels solid and the hex head seated perfectly with a standard wrench. They're exactly what I needed for heavy machinery mounting.

Used these on a piece of heavy equipment I was rebuilding, and the coarse threads grabbed perfectly in the existing tapped holes. The partially threaded shaft gave just the right amount of grip without bottoming out. Solid quality for the price.

Finally got these installed on some heavy-duty assembly jigs, and the USA-made A307 Grade B steel feels solid and precise. The 3/4-10 threads cut cleanly with no binding, and the 3" length was perfect for my application.
