ENGINEER DR-27 Ultra Thin Ratchet Driver Offset Ratcheting Bit Driver

If the inner hole is 2mm, this will fit. The inner hole on an M2 is 1.5 mm. Have to hollow out the inner hole of an M2 bolt to get it to work. Works great on M3 bolts tho. Tool steel.

I love this ratchet so much. I keep it in my jacket's pocket and if I suddenly have a need for a screw driver, I don't have to run to my tool box. I am a HUGE fan of Engineer's product and this is one of their product of perfection. The built in PH-2 is quite workable for many cases and in case you need a long driver head, all 1/4 inch hex bits work just fine. The back side of the ratchet is a nice flat surface which I can press in to apply pressure to prevent the bit from slipping out or prevent the ratchet from going reverse when the screw is loose. With a thickness of less than 18mm, there is lot of room to work in the most confined space.

2.5～3mm用で、ナメてしまったステンレスのホーローセット外径５ｍｍ（2.5mmレンチ）を緩めることができました。グリップは専用ではなくて、差し替え式の　ベッセル　ボールグリップ ビット差替グリップ 220W　を使いました。

思ったより、動きが渋い。使って行く内に馴染むかな?狭い場所が多い、バイク整備には使い勝手抜群。9.5sqのアタッチが有れば尚良し。

ラチェット数がもう少し細かいほうが使いやすいと感じた。
