Primer-Free ll Inserts feature a proprietary coating that protects the base material from corrosion, provides excellent lubricity, and eliminates the need for liquid chromate primers.

Heli-Coil Primer-Free II Inserts, from Stanley Engineered Fastening, are designed for use in applications where galvanic corrosion between dissimilar metals is a concern. Available in Canada from Gould Fasteners, these inserts not only eliminate the need for primers and epoxies, but they’ve also been proven to reduce installation time, resulting in significant cost savings.

Key details

Primer-Free ll Inserts feature a proprietary coating that protects the base material from corrosion, provides excellent lubricity, and eliminates the need for liquid chromate primers. This results in significant savings — in excess of 20 per cent — thanks in large part to eliminating the application of the liquid chromate primer, which is a labour intensive process and often results in inconsistent coverage of the threads. The result: customers get a reliable solution that is faster, and cheaper, to install.

In addition, Primer-Free ll Inserts are always evenly coated, which results in more accurate bolt torques.

Proven effective

Primer-Free ll Inserts have undergone extensive salt fog testing per ASTM B-117. After exposure, the samples were sectioned to expose the threaded insert for examination. This testing revealed that, when protecting against galvanic corrosion, Primer-Free ll inserts consistently meet or exceed the performance of insert assemblies containing liquid chromate primer.

Additional details

These units are RoHS compliant, hexavalent chromium free, and they meet the strict standards of the aerospace industry. They are ideal for aluminum and magnesium applications.
