Technical Specifications & Material Science
The bolt is manufactured from ASTM A193 B8M CL2, a molybdenum-bearing austenitic stainless steel. This grade is specifically chosen for its enhanced resistance to pitting and crevice corrosion, particularly in chloride-rich environments. The CL2 (Class 2) designation indicates that the material has been strain-hardened, offering elevated tensile and yield strengths compared to standard B8 material, making it suitable for high-pressure bolting applications. The accompanying nuts are produced from ASTM A194 8M, ensuring matched metallurgical compatibility to prevent galvanic corrosion and maintain clamping force under thermal cycling.

The fastener features a 7/8 Inch nominal size and a 110 mm length, with a 9UNC thread configuration. The threads are manufactured to Class 2A (external) and Class 2B (internal) tolerances per ASME standards, guaranteeing a smooth, consistent fit that minimizes galling—a common issue with stainless steel fasteners. Strict adherence to the ASME B18.31.2 standard validates the thread profile and head dimensions, ensuring interchangeability and compliance with global engineering codes.
