## Long description

Knurled collar SCHROFF SCR. KNURL. M2.5x12.3 is a rack accessory designed to provide a secure and repeatable fastening point for components installed with M2.5 screws. The metal collar features a knurled outer surface that improves grip for finger-tightening or tool-assisted installation, and its compact length is suited to mounting in equipment racks and chassis where stable, vibration-resistant fixing is required. This accessory is intended for use in server, telecom and electronics assemblies that demand reliable mechanical connections without frequent loosening.
Advantages
The knurled profile enables ergonomic hand operation while maintaining compatibility with standard M2.5 fastening hardware. Manufactured from metal, the collar offers dimensional stability and resistance to wear during repeated installations. Its design allows for precise, repeatable positioning of panels, modules or components, reducing the risk of misalignment. The compact form factor minimizes interference with adjacent parts and supports installations in dense rack environments.
Suitable for
Fixing front panels, subracks and mounting brackets in equipment racks
Securing modules and daughterboards inside chassis
Applications in server rooms, telecom cabinets and network enclosures
Maintenance and upgrade tasks requiring frequent manual screw access
Key specifications
Screw compatibility: M2.5
Overall length: 12.3 mm
Material: metal (knurled outer surface)
Surface finish: machined/knurled for improved grip
Function: hand-tightenable collar for repeatable fastening
How to use
Position the knurled collar in the designated threaded or clearance hole on the rack or chassis and align the mating component. Insert an M2.5 screw through the component into the collar and rotate until properly seated. For hand tightening, use the knurled surface to obtain a firm grip; a screwdriver or appropriate tool can be used for additional torque if required. Ensure the collar is flush with the mounting surface and that the fastening provides the necessary mechanical stability without over-torquing.
Usage recommendations
Inspect mating threads and the knurled surface before installation to remove debris. Use consistent torque values when assembling multiple fastenings to maintain alignment. In high-vibration environments consider applying a compatible locking method if increased resistance to loosening is required.
