Arrowmax AM-450279 5/16' Nut Driver 7.938MM x 100mm Honeycomb Field-Sized Driver  [AM-450279]

Accurate Maintenance Tool for Models

The Arrowmax AM-450279 nut driver delivers the 5/16" (7.938mm) fit you need for typical RC hardware while keeping the tool light for portable use. Its compact profile makes it handy for pit lanes and bench sessions.

Light Honeycomb Handle

The honeycomb-style hollow handle cuts weight and improves balance so you can manoeuvre the driver easily. The pattern gives a confident hold for both quick fixes and longer assembly jobs.

Hardened Spring Steel Tip

Constructed from spring steel, the tip resists deformation under load. A titanium nitride coating further increases surface hardness and wear resistance so the tip stays true through repeated use.

Lexan End Cap for Smooth Control

A lexan bottom cover provides a defined stop and a clear point of contact for controlled torque application. This helps when making fine adjustments on fragile RC parts.
