For Castings and Soft Metals HRB 70 / HB 125 or less

PEM® 300 Series Stainless Steel CASTSERT™ inserts provide strong, durable metal threads in soft metals and die-cast alloys. The simple press-in and rapid installation process for these inserts uses a flat punch and anvil to install all sizes and lengths, approximately 80% faster than other methods.


  • Designed for flush installation with flat punch and anvil into blind holes or thru-holes
  • Process cost savings vs. coil inserts or thread tapping
  • Installed into drilled holes or as-cast holes with low draft angle
  • Pilot for rapid seating and self-alignment
  • Symmetric for auto-feed capability

    • Fastener drawings and models are available at www.pemnet.com

    1 Draft hole performance will vary greatly depending on length of engagement of the knurl over the installed length. For best results, recommend use of 3 degree or less total draft and design hole as close to H as possible at depth R to optimize length and depth of knurl engagement.
