    Stainless Steel Flanged Spade-Head Thumb Screws

    Image of Product. Front orientation. Thumb Screws. Stainless Steel Flanged Spade-Head Thumb Screws.
    These corrosion-resistant thumb screws have a built-in flange that distributes pressure in thin and soft materials—no washer needed. It also provides extra surface area under the screw head to hold down material. The head of these thumb screws is slim and flat like a coin for extra leverage when twisting.
    Length is measured from under the flange.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
