1/2-13 x 5" ソケットキャップスクリュー | ボタンヘッド六角穴付き | 合金鋼熱処理黒色酸化 (25個入り)

I was impressed by the precise hex socket drive on these bolts; they fit my wrench perfectly without any wobble. The 5-inch length was just right for securing a heavy-duty jig I’m building.

The black oxide finish gives them a clean, professional look, and the threads cut smoothly into my steel jig without any binding. I grabbed a pack for a custom tooling project and they’ve held up perfectly under torque — exactly what I needed.

The hex socket drive fits my ratchet set perfectly, and the threads cut cleanly into steel plate without any binding. These bolts are solid for heavy jig work.
