MC-4000WHITE : White Nylon Needle Pin

MC-4000WHITE IC Tube End Stop Pin

MC-4000WHITE is a white nylon needle pin for IC shipping tubes with matching punched retention holes. A correctly seated pin helps keep components from sliding out during handling, storage, and shipment.

Drawing and reference dimensions

Check the retention section as well as the straight shank. These pin dimensions do not specify the required tube-hole diameter or establish fit with every IC shipping tube. Open the dimensioned drawing.

Installation and removal

Insert the pin through the intended retention hole and check that its retention feature engages without distorting the tube. Keep the pin clear of device leads and fragile surfaces. Support the tube when removing the pin; review the MC-1000PP pin puller where the tool can engage beneath the pin head. Inspect the pin and hole before reuse.

Static control and partial loads

Nylon identifies the polymer, not an electrical rating. Confirm any ESD requirements for this exact part; white color does not establish static-control performance. A pin provides mechanical retention and does not by itself establish discharge shielding.

A pin can retain components while leaving room for movement inside the tube. For partial loads, select an ESD tube filler to suit the remaining usable space. Ask Malaster to review your tube and pin combination, or compare end stop pins.
