1"-8 X 5-1/2" ヘビーヘックスキャップスクリュー | ASTM A193 B7 合金鋼無処理 | 部分ねじ (25個/パッケージ)

These bolts handled the high-torque job on my press without any sign of stress, and the partial threading made alignment a breeze. The plain finish is exactly what I needed for a clean industrial look, and the 5-1/2" length gave me plenty of grip for my heavy assembly.

The 1"-8 threads match up perfectly with my existing nuts, and the B7 alloy has that solid, industrial heft I want for heavy equipment. These are exactly what my assembly needed.

The threads cut cleanly into the receiver on my press, and the plain finish holds up well under heavy clamping pressure. No wobble at all after cinching them down to torque spec.
