Industrial Fasteners
Industrial fasteners are essential mechanical components used to create secure, reliable and serviceable connections across industrial equipment, structures, machinery and process systems. Depending on the application, industrial fasteners may include bolts, stud bolts, nuts, washers, threaded rods, socket head cap screws and specialised custom fasteners.
Industrial Engineering Works supplies industrial fasteners for demanding applications across Oil & Gas, petrochemical, power generation, chemical processing, offshore, marine, construction, mining and heavy engineering industries. Products are available in carbon steel, alloy steel, stainless steel, duplex, super duplex, nickel alloys and other specified materials.
Fasteners can be supplied according to applicable ASTM, ASME, DIN, ISO and ANSI standards, with custom dimensions, threads, finishes, testing and documentation available according to project requirements.

Common Questions About IEW
What is API 20E?
API 20E is an API specification covering bolting materials used in critical applications within the petroleum and natural gas industry. It defines requirements related to qualification, production, manufacturing controls, testing and documentation.
What is the difference between API 20E and API 20F?
API 20E and API 20F are separate API specifications addressing different categories of Industrial Engineering Works requirements. The applicable specification should be selected according to the equipment, application and project requirements.
What are BSL-1, BSL-2 and BSL-3?
BSL-1, BSL-2 and BSL-3 are Bolting Specification Levels under API 20E. They represent different levels of qualification, manufacturing controls, testing and quality requirements, with higher BSL levels generally involving more stringent requirements.
Which industries use API 20E fasteners?
API 20E fasteners are primarily used in critical applications within the Oil & Gas industry, including wellheads, Christmas trees, blowout preventers, pressure-control equipment, subsea equipment, valves, pipelines and drilling equipment.
