The Arrowmax AM-111140 Allen Wrench Tip at 4.0 x 120mm is produced from spring steel to handle torsional stress without deforming. It is aimed at RC enthusiasts who need a reliable hex tip that stays true through repeated servicing. The machining yields a clean, accurate fit on 4.0mm hex fasteners.
Spring steel construction delivers a combination of toughness and slight resilience, which reduces wear on both the tool and fastener faces. The 120mm length increases accessibility for screws situated deep within models or around crowded components.
This tip suits a wide range of maintenance chores such as shock tuning, servo mounting and motor securing. It gives steady control so you can make precise turns without slipping off the hex.
