The M8 \u00d7 104.25 mm custom threaded studs for machine tools<\/strong>, supplied by EFS \u2013 European Fasteners Solutions according to specific customer requirements, represent one of the most technically demanding applications of special fasteners used in high-stress industrial production lines.<\/p>\n

These custom threaded studs for machine tools are produced in quenched and tempered 39NiCrMo3 alloy steel, strength class 10.9<\/strong>, and ensure mechanical strength, dimensional stability, and long-term reliability under dynamic and cyclic loads.<\/p>\n

Threaded studs are fasteners with threads at both ends, designed to ensure solid and secure connections between multiple mechanical components.
\nIn some scenarios they may also be referred to as stud bolts, especially when used with nuts on both sides.<\/p>\n

Materials and Surface Treatments: 39NiCrMo3 Steel and Electroless Nickel Plating<\/strong><\/h2>\n

The 39NiCrMo3 <\/strong>nickel-chromium-molybdenum alloy steel offers an excellent combination of hardness, toughness, and fatigue resistance.
\nThe quenching and tempering treatment <\/strong>provides all mechanical properties required for class 10.9 fasteners, making these custom threaded studs for machine tools suitable for vibration, alternating loads, and severe operating conditions.<\/p>\n

The subsequent electroless nickel plating<\/strong> guarantees uniform protection even on complex geometries such as threads, internal corners, and recesses \u2014 precisely where traditional electrolytic coatings tend to fail.
\nBecause this coating is deposited through an auto-catalytic chemical reaction, it ensures uniform layer thickness and tight dimensional tolerances.<\/strong><\/p>\n

These are essential for precision assemblies in machine tools.<\/p>\n

Rolled Threads: Optimized Geometry and Enhanced Fatigue Strength<\/strong><\/h2>\n

The threads of these custom threaded studs for machine tools are produced by cold thread rolling.<\/strong><\/p>\n

But, what is the cold thread rolling?<\/p>\n

Cold thread rolling is a plastic deformation process in which hardened dies form the thread profile without removing material.<\/strong>
\nThis technique, widely used for high-performance fasteners, creates a denser and stronger surface structure than cut threads.<\/p>\n

During thread rolling:<\/p>\n
