Aerospace fasteners now made under licence

SPS Technologies Aerospace Fasteners Group has been licensed by Californian manufacturer PB Fasteners to manufacture Sleevebolt assemblies, which are two piece components used for interference fit applications where fatigue enhancement is required or as a hole fill fastener in composite type applications.

The assembly consists of a tapered bolt and an internally tapered flanged outer sleeve for use in straight-sided clearance holes. Interference fit, in proportion to the bolt protrusion, is actuated as the bolt head comes in contact with the structure. The bolt component is available with a 100º flush or 12-point low profile protruding head configuration. Available materials include nickel alloy 718, titanium and MP35N. The sleeve component is manufactured from corrosion or heat resistant stainless steels. In addition, the mating washer nut assembly is also available in both nickel alloy 718 and A-286 corrosion and heat resistant steel. SPS Technologies supplies high-strength fasteners for commercial and military aircraft, jet engines and other applications requiring reliability for critical applications.
