Delrin® - Locking Nose Retractable Plunger with Nylon Patch

This retractable locking nose plunger from JBF National features a nylon thread coating to ensure ultimate thread locking, a radiused Delrin nose for maximum hole engagement, and the highest quality zinc plated 12L15 steel or 303 stainless steel. A simple 90 degree twist engages the locking element, thereby holding the plunger in the retracted position until disengaged by a reverse twist. This retractable plunger (also known as an indexing plunger) has been designed and tested to withstand side loading. Please see component diagram below.
