Custom Standoffs for UAV Avionics
We machine custom standoffs and spacers for industrial UAV and UAS programs, holding avionics boards, payload electronics and sensor plates at a set height. Each one is made from your drawing or size table.
Standoffs space and fix avionics boards, payload electronics, sensor plates and structural plates at a set height in industrial UAVs. We machine each one to your length, thread, body shape and material.
We build them from a few pieces for a prototype stack to repeat batches. Drone standoffs sit in our structural UAV components family and are also listed with our mechanical connector components.
Internal thread at both ends, so each level is fixed with its own screw. Typical in avionics board stacks and under sensor plates.
Request a quoteA threaded stud at one end and an internal thread at the other, so standoffs screw into each other to stack several levels. Typical on multi-level stacks and on antenna and GPS mounts.
Request a quoteA hex body is tightened with a wrench and suits tight access; a round body saves weight on payload trays. On aluminum, either body takes black or color anodized finishes (MIL-A-8625 Type II).
Request a quoteAn unthreaded spacer has a screw passing through it and sets plate spacing in the airframe. Blocks that join plates at an angle are covered by our drone fastening blocks.
Request a quoteA shoulder standoff adds a locating shoulder; a captive standoff keeps its screw retained. Both suit payload electronics trays that are removed often from the airframe.

Specify length (tight where stack height matters), thread size and depth, hex or round body, lightening holes or anti-rotation flats, end-face perpendicularity and finish.
When several boards or plates are stacked, standoff length errors add up. A tight length tolerance keeps connectors aligned between levels; the boards themselves are covered by our control unit plates.
ISO metric coarse threads (ISO 261 / ISO 262), typically M2.5 to M5 as set by the design, with 6H internal and 6g external classes. Threaded holes in the plates are often reinforced with screw-mount inserts.
Aluminum standoffs can carry the ground path between boards and the frame; PEEK or nylon standoffs insulate electronics from it. Chem film (MIL-DTL-5541) keeps aluminum conductive for grounding.
Rigid standoffs for sensors that must stay aligned; damped mounting with isolators where electronics must be decoupled from the airframe. Our titanium UAV parts add strength and vibration resistance in a small section.
Stack height leaves room for connectors, and for cooling air around the boards: standoff length sets both clearances.
