Challenge: Solar arrays must remain securely stowed during launch and deploy reliably in orbit. Bolted joints must maintain preload through vibration and thermal expansion without adding excess mass.

Solution: Boltight® hydraulic tensioners offer compact bolting solutions that maintain consistent preload during launch and enable reliable deployment in space. Tooling is used to tighten bolts in pure tension and then is removed, ideal for tight assemblies.

Challenge: Attitude control systems rely on precise alignment and vibration isolation. Even minor shifts in bolted joints can cause drift or misalignment, degrading mission performance.

Solution: Superbolt® tensioners provide accurate, vibration-resistant preload for mounting sensitive components like reaction wheels and gyroscopes. Operation can be performed using simple hand tools, supporting cleanroom assembly and ensuring consistent clamping force across all fasteners.

Challenge: Radiator panels must maintain structural integrity and thermal contact under orbital thermal cycling. Uneven preload can cause warping, joint fatigue, or loss of thermal efficiency.

Solution: Superbolt tensioners deliver uniform clamping force across panel interfaces, preventing distortion and maintaining thermal performance. Their corrosion-resistant materials and preload retention capabilities support long-term operation in space.

Challenge: Scientific instruments and sensors must be securely mounted with minimal space and mass impact. Bolted joints must provide high preload without compromising payload layout or accessibility.

Solution: Boltight hydraulic tensioners offer high-strength, compact bolting for payload bay interfaces. Their precision preload ensures secure fastening of sensitive equipment while minimizing space requirements and assembly time.

Challenge: Critical bolted connections must remain secure throughout transport and launch.

Solution: Nord-Lock® wedge-locking washers prevent bolted joints from loosening under the extreme conditions of satellite transport and launch, guaranteeing reliable performance in one of the harshest operational environments.
