Posi-Hex™ Ball Plungers – Ceramic

Posi-Hex™ Ceramic Ball Plungers are self-contained spring loaded devices for indexing, locating and positioning. The hex-drive design allows installation and removal using a hex wrench and provides controlled end forces with side-load tolerance. A stainless steel body with a ceramic ball delivers non-marring contact with high-temperature tolerance, corrosion resistance and electrical insulation and is non-magnetic and cleanroom compatible. Available in ANSI thread sizes 6-40 through 5/8-11 with optional thread lock. Not available in metric.
