Avoiding the "False Economy": BS EN 15048 vs. Generic Fasteners

Описание: In structural steelwork, the phrase "a bolt is just a bolt" is one of the most dangerous misconceptions in modern construction. While generic DIN fasteners might look similar to certified assemblies, the difference in safety, legality, and performance is massive.

In this masterclass produced for Andrews Fasteners Ltd, we dive deep into the critical role of BS EN 15048 non-preloaded structural bolting assemblies. We explore why buying separate components (like ISO 4014 bolts and ISO 4032 nuts) to save a few pence creates an unacceptable risk to your project’s integrity and your professional liability.

What you will learn in this video:

The False Economy: Why tiny upfront savings on generic fasteners are dwarfed by the risks of structural failure and invalidated insurance.

Legal Compliance: Understanding the unbreakable chain from Eurocode 3 and BS EN 1090-2 to the mandatory use of BS EN 15048. Under the Construction Products Regulation (CPR), using non-compliant fasteners in load-bearing steel is illegal.

The Science of Suitability: We explain the "Suitability Test" (BS EN 15048-2), which ensures the bolt and nut work as a matched pair. Learn how certified assemblies fail safely through ductile elongation rather than catastrophic, sudden thread stripping.

Factory Production Control (FPC): The importance of single-source responsibility to prevent "galling" and ensure perfectly matched coating tolerances on galvanised fasteners.

On-Site Inspection Checklist: A practical guide for engineers and inspectors. Learn how to identify the "SB" (Structural Bolting) mark, verify UKCA/CE markings, and check the Declaration of Performance (DoP).

The Andrews Fasteners Solution: Why sourcing from a UKCA and CE-approved specialist is the only way to guarantee total peace of mind and project compliance.

Your reputation is built on steel—make sure you know what is holding it together.
