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).
How corrosion-resistant is this stainless steel fastener?
Stainless steel fasteners resist rust and corrosion in most environments. For specific corrosion requirements, consult our engineering team or the appropriate ASTM specification.
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.
