Ball Plunger – Stainless Steel

SKU: CL-20-SBP-1 Category:


Self-contained ball-and-spring device available in many sizes and forces. The version shown here has a stainless steel body for extra corrosion resistance, and a 440C stainless steel ball. Available in a wide range of thread sizes from #4-48 to 5/8-11 (M3 to M16 in metric), most with a choice of light, medium, or heavy spring force. 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.
