API 20E Stud Bolts for Critical Oil & Gas Applications
API 20E Stud Bolts are critical-service bolting products used in demanding Oil & Gas and industrial applications where material qualification, manufacturing controls, traceability and mechanical performance are essential.
API 20E defines requirements for bolting materials used in critical applications. Compared with conventional stud bolts, API 20E compliant bolting involves defined qualification, production, testing and documentation requirements.
API 20E stud bolts are commonly used in offshore drilling, refineries, petrochemical plants, LNG facilities, wellheads, pressure vessels, valves, blowout preventers and other critical equipment.
Available Bolting Specification Levels (BSL)
Basic Applications
BSL-1 stud bolts are used for applications requiring the applicable baseline requirements defined for API 20E bolting materials.
Higher Quality Requirements
BSL-2 stud bolts are used where additional qualification, manufacturing controls, testing and quality requirements are specified.
Critical Offshore and Subsea Applications
BSL-3 stud bolts are intended for applications where enhanced qualification and stricter quality requirements are specified, including selected critical offshore and subsea applications.

Frequently Asked Questions
What are API 20E Stud Bolts?
API 20E stud bolts are critical-service stud bolts manufactured or supplied according to applicable API 20E requirements for bolting materials used in critical Oil & Gas and industrial applications.
What is the difference between API 20E and ASTM A193 B7?
API 20E establishes requirements for the qualification and control of bolting materials used in critical applications, while ASTM A193 B7 is a material specification for alloy-steel bolting used primarily in high-temperature and high-pressure service. An API 20E stud bolt may use an applicable material grade, such as an ASTM-specified grade, when it meets the relevant API 20E requirements.
What are BSL-1, BSL-2 and BSL-3?
BSpecification Levels under API 20E. They represent different levels of qualification, maSL-1, BSL-2 and BSL-3 are Bolting nufacturing controls, testing and quality requirements, with higher levels generally involving more stringent requirements.
Which industries use API 20E Stud Bolts?
API 20E stud bolts are used across Oil & Gas, offshore drilling, refineries, petrochemical plants, LNG, pressure equipment, wellhead systems, subsea equipment, pipelines and other critical industrial applications.
Can API 20E Stud Bolts be manufactured in custom sizes?
Yes. API 20E stud bolts can be supplied in custom sizes according to the required diameter, length, thread configuration, material grade and applicable customer specification.
Do you provide inspection certificates?
Yes. Applicable inspection and quality documentation can be provided according to the product specification, project requirements and customer requirements.
