    Self-Retaining Washers

    Image of Product. Front orientation. Contains Annotated. Washers. Self-Retaining Washers.
    Save time by assembling screws and washers in advance. The tabs on these washers grip the screw shank, so they won't slip off, even when fastening upside down or at odd angles. They take the pressure off screws and nuts to protect mounting surfaces.
    Nylon—The most popular plastic washers, these are strong, durable, and economical. Nylon will swell and weaken when exposed to moisture, so these washers are best for dry environments.
    Flexible Polyethylene—Softer and more flexible than other washers, these are a good choice when your mounting surface is slightly uneven. They also withstand vibration and movement without cracking.
