Mounting System Fundamentals<\/h3>\n

In the field of Fluid Contamination Control and hydraulic component management, the fastening architecture plays a critical role. The STAUFF Heavy Series Mounting Rail Type STSV<\/strong> provides the fundamental base element for the Heavy Series structure. The inherent robustness of the Heavy Series ensures operational stability under all supported industrial operating conditions. Thanks to its seamless integration with the full range of mechanical accessories, the STAUFF Heavy Series Mounting Rail Type STSV ensures correct alignment and optimum tensioning of the support assemblies.<\/p>\n

Classification and STAUFF Group Compatibility<\/h3>\n

The versatility of the STAUFF Heavy Series Mounting Rail Type STSV is confirmed by its compatibility with STAUFF DIN 4S (Group 2) and STAUFF DIN 5S (Group 3) standards. The system does not operate as an isolated element, but interfaces with a range of fastening devices (Further Metal Hardware). These include Type GMV Mounting Rail Nuts and Type CRA Channel Rail Adaptors. Both components are specifically designed for use with Groups 4S and 5S of the Heavy Series, ensuring uncompromising mechanical retention.<\/p>\n

Primary Fastening: Hexagon Head Bolts and Socket Head Cap Screws<\/h3>\n

For optimum fastening, the system includes the use of Type AS Hexagon Head Bolts compliant with the international DIN 931\/933 and ANSI\/ASME B18.2.1 standards. The operating dimensions, used in combination with the DPAD Cover Plate, include sizes such as M10x60 and M10x70 for the metric system, and UNC variants such as 3\/8-16 UNC x 2-1\/4 and 2-3\/4. All threaded sections are available with both ISO Metric and Unified Coarse Thread (UNC). These are complemented by Type IS Hexagon Socket Head Cap Screws and Type AF Stacking Bolts, designed for the same 4S and 5S categories.<\/p>\n

Material Engineering and Surface Finishes<\/h3>\n

The performance of the STAUFF Heavy Series Mounting Rail Type STSV is directly related to the Material Codes selected for the fastening components:<\/p>\n

    \n
  • Code W1:<\/strong> Uses Carbon Steel in its uncoated version.<\/li>\n
  • Code W3:<\/strong> Uses zinc\/nickel-plated Carbon Steel, defined as the standard finish option for applications in North America.<\/li>\n
  • Code W4:<\/strong> Uses V2A Stainless Steel compliant with grades 1.4301\/1.4305 and AISI 304\/303.<\/li>\n
  • Code W5:<\/strong> Represents the highest-grade configuration, using V4A Stainless Steel (1.4401\/1.4571 – AISI 316\/316 Ti).<\/li>\n<\/ul>\n

    Additional alternative materials and specific surface finishes are available upon request. Furthermore, for systems exposed to severe vibration and dynamic stress, the use of Type SI Safety Lock Washers is specified to prevent AS bolts from loosening, together with Type SIPD Safety Locking Plates for Groups 4S-D and 5S-D of the Heavy Twin Series.<\/p>\n
