براغي رأس سداسي 7/16-20 × 4 بوصة | صناعة أمريكية | فولاذ سبائكي درجة L9 زنك أصفر | جزئي الخيط (25/عبوة)

The hex head works perfectly with my socket set, and the yellow zinc finish on these Grade L9 bolts looks like it will hold up well in my shop equipment. For a 25-pack of partially threaded 4-inch screws, the price felt fair for the USA-made quality.

These bolts are exactly what I needed for a heavy-duty machinery repair. The partially threaded shank made alignment much easier than fully threaded bolts would have.

These bolts threaded smoothly into my tractor’s mounting brackets without any binding—the partially threaded shaft made alignment much easier. The yellow zinc finish looks solid and the L9 grade gives me confidence for heavy-duty use.
