Brass Screw-to-Expand Inserts for Plastic

Made from brass, these inserts are electrically conductive, nonmagnetic, and have good corrosion resistance.

18-8 Stainless Steel Screw-to-Expand Inserts for Plastic

These 18-8 stainless steel inserts have better corrosion resistance than brass inserts and may be mildly magnetic.

Aluminum Screw-to-Expand Inserts for Plastic

These aluminum inserts are 70% lighter than brass inserts, electrically conductive, and nonmagnetic. They have good corrosion resistance, which is comparable to brass but not as good as stainless steel.

Brass Flanged Screw-to-Expand Inserts for Plastic

Made from brass, these inserts are nonmagnetic, corrosion resistant, and electrically conductive.
