    ASTM A193 B8 Class 1 Stainless Steel Screws Nuts Bolts Heavy Hex Screws

    ASTM A193 Class1 B8 Stainless Steel Hex Bolts Heavy Hex Head Screws


    Product Description:


    These Grade B8 screws are made from 18-8 stainless steel and have good chemical resistance.

    They may be mildly magnetic.

    Also known as pressure bolts, these screws meet the high-pressure and high-temperature regulations of ASTM A193 and are used to secure pressure tanks, valves, and flanges.

    Length is measured from under the head.

    Screws should be used with ASTM A194 Grade 8 nuts.

    Partially threaded screws come with precise threaded and unthreaded portions, allowing you to place only the stronger unthreaded portion (grip) in joints subjected to sideways forces.
