    3. Application

     

    Hex Flange Screws are commonly called Frame Bolts because of their popularity in the trucking industry for use on assembly of truck frame rails. Hex Flange Screws are also used on pipe flange applications because the larger bearing area under the head helps ensure that the gasket is uniformly compressed to eliminate leaks. Hex Flange Screw can be used in any assembly that is currently using a hex cap screw and washer to eliminate the washer.

    Earnest Machine Products line of Hex Flange Screws are made to the dimensions specified in the Industrial Fasteners Institute standard IFI -111. The head is manufactured with a full trimmed hex to prevent wrench slipping and rounding of the hex during installation or removal. The bearing faces are smooth to ensure uniform torque tension performance and that maximum clamp loads are achieved.
