This round steel SMT spacer provides an internal M2.5 thread for creating a compact threaded mounting point directly on a PCB or assembly.
It is reflow compatible, so it can be placed during surface-mount assembly and soldered using solder cream. The spacer has a tin surface finish and is supplied as an individual unit.
Specifications:
- Operating Temperature: -55°C up to +150°C
- Material: Steel
- Surface: Tin
- Inner Thread: M2.5
- Length: 1.5mm
- Outer Diameter: 5.1mm
- Inner Diameter: 3.5mm
- Solder Cream Thickness (Value): 150 µm
- Tightening Torque: 0.35 N*m
Useful for compact electronics builds where a soldered, internally threaded steel spacer is needed for M2.5 hardware.
Jargon buster
Plain-language definitions for the technical terms used above.
- M2.5
- A metric screw thread size with a 2.5 mm nominal diameter. It matters for mounting because screws, standoffs, and holes must use the same size to fit securely without damaging the board.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- Thread
- A low-power wireless mesh networking standard designed for smart home and IoT devices. It matters because Thread devices can relay messages through each other, helping build reliable networks for sensors and controllers.
- Torque
- A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
