Arrowmax AM-413140 4.0mm Tungsten Steel Allen Wrench Tip 120mm  [AM-413140]

Precision 4.0mm Tungsten Tip for RC Repair

The Arrowmax AM-413140 Allen wrench tip is machined from tungsten steel for long-lasting use. With a 4.0mm tip diameter and a 120mm overall length, it gives the reach and accuracy needed for routine RC setup and adjustments.

Durable Tungsten Steel Construction

Tungsten steel resists rounding and wear under repeated torque, so the tip keeps its shape after many sessions. That makes it a dependable choice for hobbyists who work on cars and trucks often.

Uses Around the Workshop

The 4.0mm size suits common hex screws in 1/10 scale models. Use it for tightening suspension mounts, setting pinion gears, or any task requiring a slim, long hex tool for confined spaces.
