MIP9801

Overview

The MIP 4.0MM Nut Driver Wrench Gen 2 (MIP9801) is an essential tool for any serious RC enthusiast in the UK. Whether you're tuning your RC car, maintaining your latest model, or performing routine adjustments, this precision nut driver delivers the rock-solid construction and tight tolerances that have made MIP the go-to brand for RC maintenance tools for nearly 30 years. The Gen 2 refinement brings modern enhancements to an already legendary tool, combining classic MIP heritage with updated features that improve durability, visibility, and usability in your workshop or at the track.

Designed and manufactured entirely in the USA, the MIP 4.0mm Nut Driver represents the pinnacle of RC tool engineering. It's trusted by World Champions and hobbyists alike around the world, and for good reason – this is the wrench that helps extract screws damaged by inferior tools, making it an invaluable addition to any RC toolkit. The 4.0mm size is particularly versatile for common fasteners found on most modern RC vehicles, making this an ideal choice whether you're running ready-to-run RC cars, race kits, or competition-grade machines.

With its iconic amber-handled design now enhanced with a black oxide coating and laser-etched markings, the Gen 2 version maintains the unmistakable MIP identity whilst offering improved protection against wear and corrosion. The short overall length improves ergonomics and control during use, whilst the thin-wall, deep socket head reaches nuts on long screws and works effectively in tight areas – essential features for accessing fasteners in confined spaces on your RC vehicle.

Key Features

• Black Oxide Coating — The Gen 2 upgrade replaces the previous nickel plating with a durable black oxide finish that provides superior protection against scratches, oxidation, and corrosion, extending the tool's lifespan and keeping it looking and performing like new for longer.
• Laser-Etched Size Markings — Clear, crisp laser-engraved markings display the MIP logo and tool size, making it impossible to miss which size you're grabbing from your toolbox, whilst ensuring the markings won't fade or wear away over time.
• Colour-Coded Identification Ring — A bold colour-coded ring allows quick visual identification of the tool size, speeding up your workflow during maintenance and tuning sessions where you need the right tool fast.
• Deep Socket Head Design — The thin-wall, deep socket configuration is specifically engineered to reach nuts located on long screws and work effectively in tight areas where standard tools simply won't fit, a critical feature for accessing fasteners in confined spaces on modern RC vehicles.
• Optimised Steel Construction — Built from premium steel and hand-assembled in the USA, the tool features optimised construction for maximum durability and long wear characteristics, ensuring it withstands the demands of regular RC maintenance.
• Super-Comfortable Polycarbonate Handle — The ergonomically designed handle is crafted from resilient polycarbonate that maintains its comfort in both hot and cold weather conditions, ensuring you can work on your RC machines regardless of the season or weather outside.
• Short Tool Length — The refined overall length improves ergonomics and control during use, reducing hand fatigue and giving you better precision when tuning critical fasteners on your RC car or truck.
• Hand-Assembled Quality — Every single tool is hand-assembled and manufactured 100% in the USA, reflecting MIP's commitment to uncompromising quality and attention to detail that professional RC enthusiasts demand.
