M12 × 120mm ソケットショルダースクリュー | ソケットヘッド | ソケットドライブ | 合金鋼 (25 / パッケージ)

The shoulder on these M12 screws is machined beautifully smooth, making them perfect as axle pins for my project. They slid into my bearing mounts with zero slop and a satisfying precision fit.

These screws came out of the pack with perfectly smooth, uniform shoulders that slide into my jig like a dream. Using them as axle pins for a heavy pivot arm, and the alloy steel has held up through constant use without a hint of wear.

The precision-ground shoulder on these screws gave my project a perfectly smooth bearing surface. They fit snugly into the hex socket and the 120mm length was just right for my axle assembly.
