Press-In Inserts for Castings & Soft Metal

PEM® 300 Series Stainless Steel CASTSERT™ inserts provide strong, durable metal threads in zinc, extruded aluminum, and die-cast magnesium and aluminum ranging in hardness HRB 50 to 80. The overall, simple press-in, installation process for these inserts uses a flat punch and anvil to install all sizes and lengths, approximately 80% faster than other methods.

  • Depth of knurl allows engagement with as-cast draft angle holes, or milled holes
  • Process cost savings vs. coil inserts or thread tapping
  • Pull-out performance varies based on panel material, length of engagement (thread size), and draft angle
  • Available in thread sizes #2-56 to 1/4-20 / M3 to M6 in two lengths per thread size
  • Installed by simply pressing the inserts into drilled or as-cast holes. Installation is accomplished using any standard press at any time during the production process.
