Nylon Insert Flange Lock Nut

Locking Insert: Purple or White Nylon (250°F Max. Performance)

Applications: Type NFLG Nylon Insert Flange Lock Nuts are used in applications where a wider bearing diameter is desired to cover the mating surface when seated, while still offering a locking element.

Advantages:
   • 360° locking Purple nylon insert will not gall threads or remove plating "better than an all-metal Flange lock nut".
   • Produces constant locking force and will not vibrate loose "can be reused up to 50 times".
   • Smooth flange bearing face delivers wide clamping surface and will not harm the mating material "better than a serrated flange".
   • Resists temperatures to 250° "in many applications these temperatures have been exceeded".
   • Can be used with Grade 2 and Grade 5 mating part.
   • Available in your required plating finish.
