Core Specifications
Stud Grade: ASTM A193 Grade B7, a high-strength chromium-molybdenum alloy steel that is heat-treated (quenched and tempered).
Dimensions: 3/4-inch diameter with a length of 130mm.
Threading: UNC (Unified Coarse), typically 10 threads per inch for this size.
Nuts: Includes two ASTM A194 Grade 2H heavy hex nuts, designed to match the high-strength requirements of B7 studs.
Finish: PTFE Green (often referred to as Xylan or Teflon coating). This fluoropolymer coating provides a low coefficient of friction and excellent resistance to chemical weathering.
