Materials and stock.

LoneStar Fasteners Hydrobolt holds over £12m of strategically sourced inventory.

Supported by the wider LoneStar Group, this unmatched capacity can be expanded with access to an additional £40m of global stock when required.

A reliable and far-reaching supply network

In an increasingly complex and unpredictable global marketplace, LoneStar Fasteners Hydrobolt has invested in a robust stockholding strategy that delivers the depth, certainty, resilience and responsiveness our critical-industry customers depend upon.

This varied stock is organised into two broad categories:

  • Finished and semi-finished fasteners.
  • An extensive range of raw materials, predominantly held in bar form.

By making these critical components and materials readily available, we strengthen our customers’ critical-industry endeavours with increased project confidence and reduced lead times.

Further competitive advantages include, but are not limited to:

  • World-leading supply resilience and reliability
  • Reduced exposure to market and material fluctuations
  • Rapid response times in the face of changing demand
  • Consistent, tested, certified product quality and supply
  • Full material certification delivered as standard
  • Compliance with customer or industry specifications
  • Access to a long-term stock and material database
  • Full batch traceability

Fastener specification and grades

Backed by one of the world’s most comprehensive inventories, we use our stock of raw material, finished and semi-finished fasteners to manufacture, test and certify high-performance components to all major energy and international standards. Available specifications include, but are not limited to, API, ASTM, NORSOK, RCC-M, ISO, BS EN plus customer OEM or end-user specs.

Finished and semi-finished fasteners

Our vast, readily available stock of approved and accredited critical bolting, fasteners and engineered components is fully traceable and available with 3.1 certificates as standard. This on-hand stock conforms predominantly to ASTM grades and dimensionally to DIN/ISO/ANSI/ASME.

Raw Material

Our strategic stock of raw material is sourced directly from the highest quality approved mills and from our unmatched international supply chain. Materials include, but are not limited to carbon steels, alloy steels, stainless steels, nickel alloys, high-temperature grades, non-ferrous marine grades, duplex and super duplex. All stocked material conforms to international and energy sector standards as well as OEM specifications.
