Self-Retaining Bolts & Nuts
Positive Lock - Protruding Head
Positive Lock - Protruding Head
Avibank positive lock protruding head bolts require the insertion of a tool to depress the plunger which releases the locking elements. The protruding head design rises above the surface of the structure for easy access and installation. Made to MS3369, MS21130, MS21125 and MS18115. Conforms to MIL-B-23964.
Positive Lock - Flush Head
Positive Lock - Flush Head
Avibank positive lock flush head bolts also require the insertion of a tool to depress the plunger which releases the locking elements. The flush head design is ideal for aerodynamic applications that require a smooth flush surface. Made to MS3369, MS21130, MS21125 and MS18115. Conforms to MIL-B-23964.
Impedance Type
Impedance Type
Impedance type bolts produce a detent effect with spring loaded balls. Made to MS27576, and MS27577. Conforms to MIL-B-83050.
Thread End Release - Pawl
Thread End Release - Pawl
Thread End Release bolts offer a self-locking feature in an extended area beyond the thread. This allows a solid shank through the grip and tensile stress area resulting in the same loads as a standard bolt but with the added safety feature of the self-locking element.
Thread End Release - Button
Thread End Release - Button
Thread End Release bolts offer a self-locking feature in an extended area beyond the thread. This allows a solid shank through the grip and tensile stress area resulting in the same loads as a standard bolt but with the added safety feature of the self-locking element.
Self Retaining Nuts
Self Retaining Nuts
Nuts for self-retaining bolts are available in a wide variety of designs and materials, with or without scallops which prevent backing off of the nut. Due to the locking elements, most self-retaining bolts require counter-bored nuts or spacers. Avibank manufactures various spacer designs which eliminates the requirement of using a special nut.
Self Retaining Adjustable Diameter Bolt
Self Retaining Adjustable Diameter Bolt
Self-Retaining Adjustable Diameter Bolts offer a positive lock and expanding elements that eliminate or reduce wear due to vibration. Provides shear strength comparable to a solid bolt, when properly installed the bolt provides high tensile strength.
Self Retaining Adjustable Diameter Bolt - Captive Nut
Self Retaining Adjustable Diameter Bolt - Captive Nut
Self-Retaining Adjustable Diameter Bolt with Captive Nut also has a positive lock and expanding elements that eliminate or reduce wear due to vibration. This bolt allows one end installation. The nut is captive to the core bolt so it can not come off from the bolt.
