J.W. Winco Spring Bolt Options Include Knobs, Internal Threads

NEW BERLIN, WI – J.W. Winco, Inc., a leading supplier of standard industrial machine components, announced it 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-complaint 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 a Push/Pull knob, it can be operated mechanically (via a pneumatic cylinder, cam plate, etc.), where the plunger pin will protrude only as long as it is in the operation mode.

An application example for the types with internal threads would be using the internal thread on the pressure side, for operation of special pressure bolts or a rod arrangement.

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.
