Frequently Asked Questions
How many times can I reuse a nylon insert lock nut?
Nylon insert lock nuts can typically be reused 5-7 times in non-critical applications before the nylon insert loses its elasticity. For safety-critical applications (automotive suspension, structural connections), use new lock nuts each time. Temperature range is -65°F to +250°F (-54°C to +121°C).
Does Black Oxide finish provide corrosion protection?
Black Oxide provides mild corrosion resistance through a controlled oxidation process. It is dimensionally stable (no plating buildup), will not chip or flake, and is suitable for indoor use. For outdoor or wet environments, additional oil coating or a different finish (zinc, stainless) is recommended.
