E-Nut® Fastening System

The E-Nut® Fastening System is a self-expanding, self-aligning, and rapidly removable top-down fastening system that replaces riveted and rivet-less nut plates. This design accommodates multiple grip lengths and allows for angular misalignment. The E-Nut® Fastening System can be installed in composite, aluminum, stainless steel, and titanium structures.

Externally Threaded (ET) Panel Fastener

The “ET” Fastening System offers a unique internal ring design that features an internal captivated non-exposed retaining ring that eliminates retaining ring damage during installation of the stud-bolt in the panel and during engagement of the stud-bolt with the receptacle. The stud-bolt holdout feature allows for easy panel installation on both curved and flat surfaces. Used on metal or composite access panels.

Internally Threaded (IT) Panel Fastener

The “IT” Fastening System offers an internal thread design with dual lead threads that features an internal captivated non-exposed retaining ring that eliminates retaining ring damage during installation. The grommet eliminates wear and elongation of the panel hole. Used on metal or composite access panels.

Ring Type (RT) Panel Fastener

The “RT” Fastening System has a stud-bolt with external dual threads to speed up operation. The three pronged retaining washer provides high load capabilities and proper orientation during installation and removal. The unique grommet design helps to eliminate wear and elongation of the fastener holes in either metallic or composite type panels.

Tapered Shank (MT) Panel Fasteners

The “MT” Fastening System has a tapered shank with internal dual lead threads for quick installation. The tapered shank improves alignment capabilities and minimizes hole wear. The internally threaded sleeve bolt eliminates damage to the sleeve bolt threads or panel during installation.

Positive Lock Panel Fastener

The AVILOK® Fastening System offers a unique ratchet design using quad lead threads that provide quick installation and removal while at the same time has a positive lock. Multiple springs in the receptacle assure against accidental release under high vibration.

Expanding (CF) Panel Fastener

The “CF” Panel Fastening System offers both radial and axial clamp-up in one simple operation. During the installation, the fastener expands in the substructure hole and induces radial forces of a predetermined magnitude on the walls of the substructure hole. Complete expansion into the substructure hole ensures proper structural loading between the door panel and the substructure.
