API 20E and 20F: Your Key to Top-Quality Bolting Solutions with Energy Bolting

In the ever-evolving landscape of global energy industries, precision and reliability are not mere aspirations; they are the foundation of success.

Welcome to Energy Bolting, a leading manufacturer of specialised fasteners and components, and your trusted partner for API 20E & 20F Bolting solutions.


API 20E & 20F: Elevating Bolting Standards

API 20E and 20F define bolting specification levels (BSL) for critical applications in the energy sector. These specifications establish technical rigor, quality assurance, and qualification prerequisites.

The highest BSL Level (BSL3) is to be used for ''critical bolting'' requirements.

Critical bolting is defined as bolting used to assemble wellbore pressure-containing parts (including end and outlet connections) or pressure-retaining parts whose failure would result in a release of wellbore fluid to the environment. .

Energy Bolting excels in meeting these standards.

Energy Bolting's commitment to quality and excellence is underlined by licensing to mark bolting with the API Monogram. API 20E-0098 BSL 1, 2 & 3, as well as API 20F-0048 BSL 2 & 3, Energy Bolting adheres to the highest industry standards.
