Plastic standoffs strip under torque and steel long nuts add unnecessary weight to FPV frames, drone builds, and PCB stack assemblies. These aluminum alloy threaded standoff long nuts deliver the right balance of strength, weight, and corrosion resistance for precision electronics and model builds where every gram and every millimeter of stack height matters.
Machined from high-strength aluminum alloy with an anodized surface finish, each standoff features a round cylindrical body with full internal metric threading (M2, M2.5, or M3) running the entire length. Available in three inner diameter sizes — M2 (OD 3.5mm), M2.5 (OD 4mm), and M3 (OD 5mm) — and lengths from 4mm to 100mm. Anodized finish standard; note that “Aluminium Color” variants are unoxidized natural aluminum. Tolerance: ±0.3mm.
These aluminum threaded standoffs are widely used in FPV model frames, airplane and car models, RC toys, drone motherboard mounts, home computers, TV mounting, office machinery, telecommunications equipment, consumer electronics, and audiovisual equipment — as connecting rods, tie rods, support columns, or PCB stack spacers between two bolted components.
Use as frame layer spacers, PCB stack standoffs, or motor mount connectors in FPV racing frames, freestyle builds, airplane models, and car models where lightweight, precisely-threaded aluminum standoffs are needed for secure, vibration-resistant assemblies.
Ideal for motherboard mounts, home computer builds, TV mounting, office machinery, telecommunications equipment, consumer electronics, and audiovisual equipment where consistent PCB stack height and secure threaded connections are required.
Suitable for use as connecting rods, tie rods, or support columns in mechanical equipment and general industrial assembly where a lightweight, corrosion-resistant aluminum threaded spacer is needed to join two bolted components at a precise distance.
Perfect for any DIY project, custom enclosure, or fabrication build where precise stack height control and a clean, lightweight threaded standoff are needed for both structural function and a tidy finished appearance.

These are fully internally threaded standoffs (long nuts / coupling nuts). The internal metric thread runs the full length of the body, allowing a bolt or screw to be threaded in from either end. They are not smooth-bore pass-through spacers.
M2 ID fits M2 metric bolts and screws. M2.5 ID fits M2.5 metric bolts and screws. M3 ID fits M3 metric bolts and screws. Select your required thread size and length from the variant options above.
M2 ID standoffs have an outer diameter of 3.5mm. M2.5 ID standoffs have an outer diameter of 4mm. M3 ID standoffs have an outer diameter of 5mm.
“Aluminium Color” refers to the natural, unoxidized aluminum finish. These variants have not been anodized and show the bare aluminum surface. All other color variants have an anodized surface treatment integrated into the aluminum for improved corrosion resistance and color durability.
Yes. These aluminum threaded standoffs are commonly used in FPV model frames as layer spacers, PCB stack standoffs, and motor mount connectors. The lightweight aluminum construction, full internal threading, and precise length tolerances make them well-suited for FPV racing and freestyle drone builds.
These threaded standoffs are manufactured to a tolerance of ±0.3mm on body length, ensuring consistent stack height across all size and length combinations.
Yes. In addition to PCB stack and frame spacer applications, these threaded standoffs can be used as connecting rods, tie rods, or support columns in mechanical equipment, office machinery, consumer electronics, and general DIY assembly where a lightweight aluminum threaded spacer is needed to join two bolted components at a precise distance.
