Post Holders have a unique 3-point contact design that inherently centers our TECHSPEC® Metric Stainless Steel Mounting Posts more accurately. The three contact pads run the entire inside length of each holder, thus ensuring a more accurate fit with our Posts. Additionally, three tapped holes allow thumbscrew orientation without removing the Post Holder from the breadboard table, base plate, or other fixture. Post hole depth is Post Holder length less 0.25” (6.35mm). Thread values are laser engraved on each Post Holder for quick integration. Locking thumbscrew included.
