Features of GN616.2 Threaded Flange Ball Spring Plunger
GN616.2 Threaded Flange Spring Plunger Title:
Push Fit Ball Plunger Threaded Flange Spring Plunger GN616.2
Ball Head Plunger Core Feature:
Flange structure: The annular flange is tightly attached to the installation surface to prevent the plunger from being too deep or loose due to vibration or impact.
Spring loading mechanism: Built in spiral spring drives the ball or plunger head to expand and contract, achieving repeated positioning and buffering.
Main material:
Shell: Carbon steel treated with blackening or AISI 303/316 stainless steel.
Plunger Tip:
Steel bolt head:Plastic plug (POM polyoxymethylene)
Spring components:AISI 631 stainless steel spring, available in standard or high load options.

Material Combinations: Flexible selection of body, ball, and spring materials；
Dimensions & Parameters: Adjustable body diameter, ball size, and spring force to meet non-standard requirements
Precision positioning of molds, guidance of automation equipment, anti loosening of heavy equipment, etc;
Ball Plunger Spring Loaded Key points for installation and maintenance
Installation steps:
Manual pre tightening
Insert the plunger vertically into the threaded hole and rotate clockwise until the flange bottom is completely in contact with the base.
Clean the threaded hole → manually screw it into the flange tight surface → fix the flange with a wrench to avoid deformation caused by excessive tightening.
Notes: Installation of Plastic Bolt Head (K-Type):
When the plug is made of POM material, avoid contact with acidic cleaning agents;
