Fasteners and bolting

High integrity, certified and approved fasteners, serving critical industry needs.

LONESTAR FASTENERS

Precision fasteners

We specialize in forging, thread rolling and machining the highest quality fasteners, working to precise customer specifications to create a truly bespoke product. Key categories include:

Precision bolts and certified fasteners

We manufacture to drawings, producing fasteners with special threads and tight tolerances, in a practically unlimited range of diameters and lengths.

ASTM studbolts

We hold one of the largest inventories of fully certified ASTM fasteners in the industry. Stock includes studbolt assemblies, as well as finished and semi finished fasteners including hex bolts, socket products, and nuts in carbon and stainless steel, plus exotic grades such as duplex, super duplex and 660. Fasteners can be supplied in accordance with PED 97/23/EC Annex 1 para 4.3.

API bolting

We manufacture and supply a full range of bolting products to conform with American Petroleum Institute standards for operational and environmental safety and efficiency.

High temperature, creep resistant fasteners

We manufacture creep resistant materials for use in high temperature applications like gas and steam turbines, aero derivative engines, steam chests, boilers, pressure vessels and valves. We specialize in turbine coupling bolts and rotor studs with very tight tolerances and concentricity typically used for coupling rotating equipment.

IFI

We manufacture products to the rigorous specifications of the Industrial Fasteners Institute, ensuring quality, safety and uniformity. Guidelines cover dimensions, mechanical properties, finish data and tightening information.

ASME

We stock and manufacture nuclear fasteners to the relevant quality standards, including NQA-1, ASME NCA 3800 and 10CFR50B.

Level 1 fasteners

Typically used in critical applications where failure could have significant consequences, these fasteners are made from non ferrous metals like Monel, K500, 718 and titanium. Often used in military contexts, they ensure reliability under extreme conditions.

Machined components and OEM parts

By collaborating with OEM companies in the oil and gas and power generation sectors, we have grown from a fastener supplier to a complete supply chain partner for engineered and turned parts.

Wind turbine fasteners and bolts

As a high integrity bolting manufacturer, we are highly active in both onshore and offshore applications, supplying critical bolting and fastening products to the developing wind energy sector.
