BN/BB – Blind Nut and Blind Bolt Fasteners

Hi-Shear Blind Fasteners

Blind fastener systems can be split into two main categories: blind nuts “BN”, and blind bolts “BB”. Blind nut fasteners have a female thread installed from one side into a structure, which later in the assembly process will receive a bolt. Blind bolts are definitive blind fasteners allowing assembly from one side and are widely used for closed structures such as flaps, spoilers and ailerons.

Jet-Tek can supply all standard Blind Nut and Blind Bolt assemblies, please contact our sales department for assistance with selecting the right assembly for your application. We have most standard BN and BB assemblies available to ship within 1-2 days, with OEM certifications included. Please call or email our sales department for pricing and delivery information on your specific requirement. Our sales department can be reached at (800) 804-7876.

Blind Nut Fasteners (BN)

The BN, Blind Nut is a simple and robust solution. Blind nut fastners are designed as a two component system combining a high strength threaded expander with a choice of sleeve in multiple materials and shapes depending on the targeted application. The Blind nut installation is suitable instead of conventional nut plates where a closed structure does not allow access from the back. Additionally, where the sub-structure does not allow holes to be drilled for the installation of conventional nut plates.
