M20-2.5 x 55mm 六角穴付きボルト | クラス8.8 スチール プレーン | 全ねじ (25本/パック)

The hex head seated perfectly with a standard socket, and the 55mm length gave me just the reach I needed for a heavy bracket. These 8.8 steel screws feel solid and held up to a good amount of torque without stripping.

Went straight into the coupling with a torque wrench and the hex head grabbed perfectly, no slipping. The 8.8 steel feels solid and the full threading made alignment a breeze. These are going to hold up fine on the press frame.

The threads are clean and sharp, so they started easily by hand — no binding or cross-threading. I needed 10 of these for a heavy equipment bracket and all 25 engaged perfectly with a wrench. Solid Class 8.8 steel that feels substantial without being brittle.
