AN4 Undrilled Cadmium Bolt

These AN4 bolts are high‑strength, aviation‑grade fasteners manufactured from heat‑treated alloy steel and finished with a cadmium plating for superior corrosion protection. Each bolt is precision‑ground for accuracy and delivers a minimum tensile strength of 125,000 PSI, making it suitable for structural and control‑system applications.

This variant features a undrilled shank. Bolt length is measured from under the head to the end of the shank, with the unthreaded portion referred to as the grip length.

AN‑series bolts meet established military and aviation specifications and are widely used across certified and experimental aircraft.
