1-1/4-7 × 2-1/2インチ ソケットキャップスクリュー | 平頭 六角ソケットドライブ | 合金鋼 サーマルブラックオキサイド (5個/パッケージ)

The black oxide finish on these flat head screws is really clean and even, and the hex socket drive makes tightening them into tight spots a breeze. I used them on a small assembly fixture and the alloy steel feels solid enough to handle repeated torque without stripping.

I needed stronger hardware for a jig I’m building, and these 11/4-7 x 2-1/2” socket cap screws fit perfectly with no wobble. The hex socket drives smoothly without stripping, and the black oxide finish looks clean.

The black oxide finish on these screws looks professional and resisted wear when I tightened them into a jig fixture. They seated perfectly flush with the material, and the hex drive held firm without stripping. Exactly what I needed for precision assembly work.
