BS 4882 Stud bolt Specification for Bolting for flanges

General requirements and details of dimensions for metric and inch series. Gives materials for use at temperatures between -250°C and 750°C.

BS 4882 is a British Standard that specifies the requirements for bolting materials for use in pressure-retaining and structural applications, particularly for high-temperature and high-pressure service. It is often referenced in industries such as oil and gas, power generation, and chemical processing.

Scope of BS-4882

  • Defines bolting materials, including stud bolts, hex bolts, and nuts.
  • Specifies requirements for chemical composition, mechanical properties, dimensions, heat treatment, and testing.
  • Covers materials suitable for use in high-temperature and high-pressure environments.
