براغي ذات رأس أسطوانية 7/8-14 × 9 بوصة | محرك سداسي | ملولبة جزئيًا | فولاذ سبائكي بأكسيد حراري أسود (20 / عبوة)

The black oxide finish on these is evenly applied, no flaking or patchy spots, which makes them look sharp in a fixture I just built. The partial threading at 9 inches gives me plenty of grip for the hardened steel plates I’m clamping together. A solid pack for the price.

The black oxide finish on these held up nicely during assembly without any flaking, and the hex socket drive made torquing them down in tight spots a breeze. Exactly the length and thread pitch I needed for my jig build.

These 9-inch long screws fit perfectly into my jig fixture, and the hex socket drive made installation straightforward. The partially threaded design gave me the grip I needed without any slippage. Really solid hardware for the price.
