As most of our products are used in quality critical applications, it’s imperative that they are of the highest integrity – failure isn’t an option. 

Wulfrun Specialised Fasteners operate a formal quality system accredited by LRQA to BS.EN.ISO 9001-2015 and are API20E BLS2 approved. In addition to this, we are able to integrate customer specific standards and quality system requirements to ensure that we meet any unique quality requirements.

The Wulfrun quality system lays down mandatory procedures and controls for all elements of our supply, from full traceability on material purchase, through to order completion. Quality is further reinforced by our on-site XRF spectrometry of all incoming material and finished products.

Our fully equipped inspection facility is complemented by our coordinate measuring machine, which allows us to perform intricate inspection operations, enabling us to produce detailed dimensional reports.
