Zygology - PEM® CASTSERT® Press-in Inserts - Metric

CAD (0) ▾

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
