Mini spring loaded pull pin, Tiny indexing plunger, Pop pin
In semiconductors or specialized machinery where large plungers won’t fit, UJEN’s mini plunger (M8–M16, 4–10mm pins) meets the challenge with a “stay-pulled” function: pull, rotate, release. The knob includes a circular ring, four styles, and seven ring/disc colors; wood fiber or oyster shell plastic helps reduce environmental impact. Taiwan CNC and mold production ensures tight tolerances and durability, while ISO9001 oversight caters to large or custom B2B needs in medical, automotive-aerospace, sports, and AV equipment.
Function
Small spring pin with rest position is ideal for fast fixing of parts, especially when the pins are constantly being removed and relocked. Pull up the knob, as the pin is pulled as well so as to allow users to quickly adjust expansion tubing. Insert back after release the knob. This pull pin can clamped the tubing with tightened by a hand (no tools needed). After the knob is pulled up, it can rest by rotated 30 degrees. It is convenient to adjust the tube with both hands. Rotated *directly to insert back after adjusting.
*This is an improved function. The old version have to "be pulled up and rotated" to insert back. The new version just be rotated directly without pulled.
