S-94710A101 M4 Flange Nuts

Key Features & Benefits at a Glance

• Superior vibration resistance with nylon insert locking that maintains secure fastening in high-motion environments up to 250°F (121°C)
• Enhanced load distribution thanks to the integrated 10.2 mm flange, reducing surface pressure and preventing damage to assembled materials
• Corrosion-resistant durability from 18-8 stainless steel construction, ensuring long-term performance in harsh industrial or outdoor settings
• Reliable, reusable locking performance as the nylon insert allows for multiple installations without significant loss of locking torque
• Precision threading with Class 6H fit for consistent engagement and reduced risk of cross-threading in metric assemblies
• Easy installation and removal using standard external hex drive tools, speeding up maintenance and assembly processes
• Environmental compliance assurance with RoHS 3 standards, meeting global regulatory requirements for hazardous substance restrictions

Professional Applications & Engineering Value

This M4 nylon insert lock flange nut addresses critical challenges in dynamic and high-vibration applications, such as automotive subsystems, machinery frames, and conveyor systems. The combination of 18-8 stainless steel and a nylon insert locking mechanism ensures that the nut resists loosening under continuous stress, while the flange design distributes clamping force over a wider area, minimizing the risk of material fatigue or surface indentation. Its metric coarse thread (0.7 mm pitch) and Class 6H thread fit provide reliable engagement with mating bolts, reducing assembly errors and maintenance downtime. Ideal for equipment exposed to temperature fluctuations and mechanical shocks, this fastener delivers reusable, vibration-resistant performance without requiring additional lock washers or adhesives.

Specification Summary & Compliance

This flange lock nut features a Class 6H thread fit per metric standards, ensuring precise dimensional accuracy for M4 x 0.7 mm coarse threads. The external hex drive (7 mm width) and right-hand threading align with common assembly practices. Manufactured from 18-8 stainless steel with a nylon insert rated to 250°F, it complies with RoHS 3 (2015/863/EU) regulations, confirming adherence to environmental and safety standards for industrial fasteners.
