The nVent SCHROFF part number 21101102 is a collar screw designed for mounting applications in rack systems. It features an M2.5 thread size with a 0.45mm pitch and measures 12.3 mm in length. The component is constructed from steel with a zinc finish to provide corrosion resistance. It utilizes a pan-head design compatible with both slotted and Pozidrive (Phillips) drive tools, ensuring secure fastening for front panels.
Verify the specific drive type requirement (slotted vs. Pozidrive) against the equipment manual, as sources indicate dual compatibility but installation tools must match the installed head configuration. Confirm that the M2.5 thread specification aligns with the tapped holes in the target rack frame or panel bracket to ensure proper engagement without cross-threading.
Select this component when working with nVent SCHROFF europacPRO or ratiopacPRO chassis systems requiring M2.5 fasteners. Ensure the application involves unshielded panels, as specified by manufacturer documentation. The zinc coating provides adequate protection for standard indoor rack environments.
This item belongs to the nVent SCHROFF accessory line for 19-inch rack infrastructure. It serves as a specialized fastener for modular enclosure systems, distinct from general-purpose self-tapping screws due to its specific collar geometry and thread pitch optimized for sheet metal panel attachment.
No public confirmed substitute part numbers are available in the provided documentation. Use only OEM parts to maintain warranty compliance and dimensional accuracy within Schroff rack systems.
