Knurled Knob Locking Nose Retractable Plungers with Nylon Patch On JBF National

JBF National's knurled knob locking nose retractable plunger comes available in steel, 303 stainless steel, 316 stainless steel, and brass. A simple 90 degree twist engages the locking element, thereby holding the plunger in the retracted position until disengaged by a reverse twist, and the knurled rim allows for maximum grip regardless of grip situation. This retractable plunger (also known as an indexing plunger) also features a nylon thread coating to ensure ultimate thread locking in heavy vibration situations.
