Asp® Fasteners

The Asp® fastener provides a simplified method of fastening composite, honeycomb, metallic or other materials that are sensitive to fastener clamp-up or installation force conditions. Clamping force can be infinitely adjustable within maximum recommended torque limits, and no further load is applied during installation. The Asp® fastener has a positive mechanical lock for use in vibration and FOD-critical installations. It installs quickly and easily, thus eliminating the need for potting, bushings, inserts or stepped hole preparation.

Expandable Diameter Fastener (EDF)

The Expandable Diameter Fasteners use tapered sleeves or bushings that, when activated, expand to create a tight fit in a hole. The sleeves can be activated by various means, including the use of a nut or bolt for torque, or other mechanisms such as a wrap-around cam handle. These fasteners provide a rigid structural joint. The radial tightness minimizes vibration and cyclic fatigue loads and helps resist shock loads. EDFs are available in a variety of materials and finishes for extreme corrosive or high temperature environments. 

E-M Stud

The E-M stud is an electrical grounding stud that was developed in response to customer requests for an improved method of installing grounding terminals. The result is a timesaving fastener that is easily installed in a loose tolerance drilled hole from one side of the work.
