    Nylon-Insert Locknuts

    Image of Product. Front orientation. Locknuts. Nylon-Insert Locknuts.
    Versatile yet economical, these are the most commonly used locknuts. The nylon insert grips the screw to prevent loosening from moderate vibration without damaging threads. However, the insert may become brittle if exposed to high temperatures. These locknuts are reusable a handful of times, but the holding power decreases with each use.
    High-Strength Lightweight Titanium
    Grade 5 Titanium—The best of both worlds, these locknuts are lightweight like aluminum and as corrosion-resistant as 316 stainless steel. They're ideal for use in chemical-processing and water-treatment facilities since they stand up to strong acids and other harsh chemicals. Grade 5 is the strongest of all the titanium alloys due to its higher aluminum and vanadium content.
