What are API 20E Fasteners?
API 20E is an API specification covering bolting materials used in critical applications within the petroleum and natural gas industry.
API 20E establishes requirements related to the qualification, production, manufacturing controls, testing and documentation of carbon steel and alloy steel bolting materials.
The specification includes different Bolting Specification Levels (BSL), with requirements becoming more stringent as the BSL increases.
API 20E fasteners are selected based on the applicable equipment requirements, material grade, service conditions and project specifications. Proper qualification and documentation help ensure that the supplied bolting meets the requirements specified for the intended application.
Where applicable, products are supplied according to the latest applicable API specification and customer requirements.
