Knurled Press-Fit Plungers

Knurled Press-Fit Plungers are press-in spring loaded devices designed without a shoulder for insertion from either end. Use where a threaded plunger is impractical or when threaded adjustments are not required. Stainless steel versions provide maximum protection against rust and corrosion. Available in steel or stainless steel with standard plunger nose or Delrin® nose options. End forces are listed as initial and final values. Not available in metric.

Specify by:

  • Body material (steel or stainless steel)
  • Nose style (standard plunger nose or Delrin® nose)
  • Knurl O.D. (0.210 in to 0.504 in)
  • End force (0.75 lbf to 8.00 lbf initial, 2.0 lbf to 18.0 lbf final)
