    The raised head gives your fingers extra space to grab these corrosion-resistant thumb screws, even with oily fingers. The knurled texture creates extra grip as you twist. Install these thumb screws on panels and covers for routinely serviced equipment, such as HVAC access doors and machine safety shields.
    Length is measured from under the collar.
    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.
