Product detail · Special Fasteners
Special fasteners are bolts, nuts, washers, pins and similar project components defined for applications that standard dimensions or geometries cannot meet.
ASTM · DIN · EN · ISO · OEM DRAWING
Product approach
Unlike flange studs, special fasteners cover non-standard geometry, dimensions, threads or material requirements for a wider range of equipment and connection applications.
Project-specific scope is established by reviewing the drawing, sample or technical specification, product type, dimensions and tolerances, thread system, material grade, finish, quantity, testing, certification and packing requirements together.
