Ball Plungers-Steel
The version has a steel body and a 440C stainless steel ball. Made in USA.
Install and/or adjust from either end. When using the slot at the ball end to install, use a Plunger Wrench instead of a screwdriver to avoid over-compressing the spring (see Related Products below). Note: the smallest sizes (#4-48, #5-40, #6-40, and M3) have no slot at the ball end. A thread-locking element holds the unit securely in place after installation.
