JBF National's t-handle locking nose retractable plunger comes available in steel, and 303 stainless steel. The t-handle design of this plunger ensures a quick and positive finger grip each time. A simple pull and twist of the t-handle 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) also features a nylon thread coating to ensure ultimate thread locking in heavy vibration situations, and a radiused Acetal nose for maximum hole engagement, and is designed and tested to withstand side loading.
