Knurled Pins - Straight Half Length Centered

Product Description
Spirol® Knurled Pins are available with full-length straight or helical knurls. The multi-crested design evenly distributes the retention force making them the ideal pins for soft materials and thin cross-sections. Suited for use in plastics for press-fit applications, these pins often replace ground dowels in applications that do not require tight tolerances of a ground dowel.
Features & Benefits
  • Numerous points of contact with the host distributes the radial stress in a uniform fashion.
  • The pin should always be harder than the host. If additional hardness is required to keep the knurls from shearing, the pins can be case hardened if .125” (3 mm) or larger.
  • Uniform and consistently high CPK's and the absence of nibs and burrs

Material: 300 Series Austenetic Stainless Steel
Finish: Plain Oiled

The following Spirol® Knurled Pins are pre-designed pins available through special order. These knurled pins are variations of the standard full-length knurled pins.
