GN 421 Hollow Knurled Knobs Nylon Plastic, With Steel or Stainless Steel Threaded Stud.
The GN 421 Hollow Knurled Knobs have a variety of applications, including clamping, adjusting, and securing. “On clamping operations, the partially protruding steel insert prevents chipping of the plastic,” said John Winkler, CEO, Office of the President at JW Winco.
The nylon plastic has a maximum heat resistance of 230 °F (110 °C). The plastic is black and smooth with a glossy finish, while the threaded stud is steel, zinc plated, blue passivated, and molded-in. The knobs are available in other colors upon request.
Hollow Knurled Knobs are appropriate for applications within the Packaging, Medical, Printing, Woodworking, Lighting and Computer Periphery industries. JW Winco also has multiple variations of the Knurled Knob like the GN 420 Hollow Knurled Knobs, with Tapped Through Steel or Stainless Steel Insert, GN 421.10 Hollow Knurled Knobs, with Brass or Plastic Tip, GN 421.11 Hollow Knurled Knobs, with Ball End, and GN 421.12 Hollow Knurled Knobs, with Ball End and Swivel Thrust Pad.
