NA51 Special Fastener Ensuring Efficiency and Safety in Gas Engine Turbines

Gas engine turbines run hot, tight and unforgiving: blades, housings and exhaust systems must stay fastened through thermal cycles, vibration and pressure swings. The BSW NA51 special fastener is engineered for that duty — high strength, corrosion and oxidation resistance, and a design that installs and removes cleanly at bolted joints sealed with flange gaskets.

What Sets the BSW NA51 Fastener Apart

Four properties explain its use where a loose connection means lost output.

• High strength — made from quality materials to precise specifications, so it holds preload under extreme conditions.
• Corrosion and oxidation resistance — suited to hot, moist and chemically aggressive environments.
• Easy installation and removal — the design seats firmly yet comes apart cleanly for maintenance work.
• Reliability — secure connections cut the risk of failures and unplanned downtime.

That reliability matters most where the smallest issue turns into lost productivity: turbine hot sections, aircraft engines and power plant equipment rarely forgive a fastener that lets go.

Where the BSW NA51 Fastener Is Used

Precision and safety drive its adoption across four demanding sectors.

• Gas engine turbines — blades, housings and exhaust systems, where robust fastening keeps components secure and supports efficient turbine operation.
• Aerospace — aircraft engines, landing gear and other critical components exposed to extreme temperatures, vibration and dynamic loading.
• High-performance vehicles — engine mounts, suspension and exhaust systems under intense vibration and stress, resisting fatigue at speed.
• Energy generation — turbine systems and plant equipment in nuclear and renewable installations, facing heat, corrosive environments and variable loads.

In power stations the same duty shows up on turbine casings, exhaust ducting and pipe flanges carrying steam or hot gas — anywhere a leak or a loose bolt stops generation.

Selection, Installation and Care

The design only pays back when it is fitted and maintained correctly.

• Confirm the duty — match fastener strength and corrosion resistance to the temperature, media and vibration of the joint.
• Control torque — tighten evenly in a cross pattern to the specified preload so vibration cannot back the joint off.
• Inspect on schedule — check for relaxation, wear and corrosion at every planned outage and replace any suspect fastener.
• Keep threads clean — clean, undamaged threads and full engagement protect the tight fit the design relies on.

Because installation and removal stay simple, planned maintenance windows stay short while critical connections remain secure.
