Nut Variant [NB102 M6FN]

The NUT [NB102 M6FN] is a high-tensile metric 6mm flange locking nut (M6FN) designed for electric scooters, e-bikes, mopeds, and light electric vehicles (LEVs). Installed across critical high-vibration assembly points—including body panel brackets, controller mounts, brake lever clamps, and light housing stays—it locks components securely against the vehicle frame chassis.

Constructed from high-strength steel alloy with a corrosion-resistant protective plating, this NB102-series nut features an integrated serrated flange face that acts as a built-in washer. Operating independently across 12V to 60V DC electric vehicle architectures, its wide flange face distributes clamping pressure evenly over mounting surfaces, preventing joint loosening, surface scoring, and structural chatter over rough roads.

Key Features

• M6 Metric Flange Profile (M6FN): Precision M6 pitch thread with an integrated wide flange base eliminates the need for separate flat washers.
• Serrated Anti-Vibration Face: Integrated locking serrations bite into the mounting surface to resist rotational loosening from road shock and motor vibration.
• High-Tensile Alloy Construction: Built from heavy-duty structural steel alloy to withstand high clamping torque without stripping or stretching.
• Corrosion & Weather Protective Finish: Surface-plated coating guards against rain, road spray, dirt, and chemical oxidation.
• Universal EV Workshop Compatibility: Hex drive matches standard 10mm EV shop wrenches and sockets for quick assembly and servicing.

Suitable Vehicle Types & Applications

• Electric Scooters & Mopeds: Primary M6 fastener for motor controller boxes, horn mounts, seat latches, and fender stays on 48V–60V e-scooters.
• E-Bikes & Light LEVs: Durable flange nut for commercial delivery two-wheelers, battery brackets, and headlight shrouds.
• General Workshop Repairs: Essential high-grade replacement hardware for replacing lost, stripped, or rusted M6 frame nuts.

System & Electrical Compatibility

• Universal EV M6 Bolts & Studs: Fully compatible with standard M6 (6mm diameter) metric frame bolts, threaded studs, and mounting brackets.
• Wide EV Sub-Circuits: Operates independently of electrical system voltage across 12V to 60V DC vehicle platforms.

1. Isolate Power & Support Component:

Turn off key ignition, trip the main DC circuit breaker, and hold the mounting bracket or component flush against the frame mounting stud.

Verification: Vehicle is completely unpowered and the bracket mounting hole aligns cleanly with the M6 bolt/stud.

2. Clean Threaded Stud & Check Joint Face:

Wipe dirt, grit, and rust away from the M6 bolt threads and bracket surface using a wire brush and cleaner.

Verification: M6 threads are clean, straight, and free of burrs or old threadlocking residue.

3. Thread NB102 M6 Flange Nut by Hand:

Place the flange face against the bracket and thread the NUT [NB102 M6FN] onto the bolt by hand to ensure smooth engagement without cross-threading.

Verification: The nut turns smoothly by hand for several turns before tool resistance is felt.

4. Torque to Specification & Verify Clamp Rigidity:

Tighten firmly with a 10mm wrench or socket to manufacturer torque specification. Verify that the serrated flange sits flush against the mounting surface.

Verification: The bracket is locked rigidly with zero play or movement when shaken by hand.

Power Isolation: Always turn off ignition, trip main DC circuit breaker, and secure vehicle before inspecting chassis or bracket hardware.

Periodic Torque Audits: Check M6 flange nut tightness during routine 3,000 km periodic servicing, especially on high-vibration motor controller and fender mounts.

Corrosion Protection: Apply a thin film of grease or protective oil over exposed external threads after installation to prevent rust in wet environments.
