J.W. Winco Canada offers GN 313 spring bolts in metric sizes
May 17, 2013 – J.W. Winco Canada Inc.—a supplier of standard industrial machine components—now offers GN 313 spring bolts in metric sizes. Versions with or without pull knob are available, as well as with or without internal thread in the plunger pin. The plunger pin in these RoHS-compliant spring bolts does not protrude in the inoperative position. It can be operated manually via the Push/Pull knob or, in the case of the types without Push/Pull knob, it can be operated mechanically (via a pneumatic cylinder, cam plate, etc.), where the plunger pin will protrude only so long as it is in the operation mode. The threaded body of the plunger is steel, with black oxide finish. Plunger pin is stainless steel, European Standard No. 1.4305 (American Standard Series 303), chemically nickel plated. Knob is matte black plastic (Polyamide PA), not removable. Lock nut is steel, black oxide finish, DIN 439/ISO 4035.
