IC Shipping Tube
End Stop Pins
Match an end stop pin to your IC shipping tube’s retention holes, wall geometry, and device clearance. Compare needle, eyelet, and long bulb styles, with drawings and tube-selection guidance.
Start with the tube and its retention holes
End stop pins pass through prepared holes in a shipping tube to help keep components from sliding out during handling, storage, and shipment. The pin’s length and retention shape must suit the tube wall, hole location, and space available around the devices.
Use the closure options listed on your IC shipping tube product page as a starting point. Compare the exact pin drawing before substituting another size or color.
Available end stop pins and pin puller
Open a product page to review its pin style, color, drawing dimensions, and documented tube options. Check how each length is measured: overall length, length below the head, and straight shank length describe different parts of a pin.

Remove pins with a supported grip
The MC-1000PP pin puller uses a slotted end to engage beneath an accessible pin head. Check the fit, support the tube, and withdraw the pin without levering against the tube wall or device leads.
Inspect the pin and retention hole before reloading. Wear, distortion, or an enlarged hole can change retention.

Needle pins
Compare the short MC-1000BLACK and MC-3000WHITE profiles with the MC-4000 styles. The short pins have different lengths and shank dimensions; they are not simply color alternatives.
Eyelet pin
MC-2000WHITE has an open eyelet retention section. Check its maximum width, engagement, and clearance through the actual tube profile.
Long bulb pin
MC-0550WHITE uses a longer shank and an end-retention feature. Compare its complete geometry with the prepared hole and device envelope.
Check the complete retained load
Confirm the hole diameter and position, wall thickness, pin engagement, and clearance to leads or other fragile surfaces. The pin should retain securely without distorting the tube. Drawing dimensions for the pin alone do not specify the required hole diameter.
A pin can keep devices inside while leaving room for them to slide. For a partial load, select an ESD tube filler to control the remaining usable space. Review the tube, closures, filler, and outer packaging together.
Confirm the material and electrical requirements for the exact part. A nylon material description or a pin’s color does not establish an ESD rating, and mechanical retention does not by itself provide discharge shielding.
Need help matching an end stop pin?
Send the tube and existing pin part numbers, a profile drawing or end-view photograph, hole dimensions and location, device dimensions, and expected quantity. Include any ESD or material requirements. Malaster can review an existing pin, another closure style, or a custom packaging arrangement.
