Ladinka 580 PCS M3 Nylon Standoff Kit
Includes black nylon spacers, screws, nuts, and threaded pillar standoffs in multiple heights (1–20 mm). Compatible with M3 standard for motherboard and PCB mounting. The non-conductive nylon construction resists corrosion and prevents electrical shorts, providing stable insulation for sensitive electronics. Suitable for computer builds, 3D printers, Raspberry Pi projects, and industrial panels. This kit offers broad compatibility and a robust supply for ongoing projects.
Marsui Sticky PCB Spacer 0.25″ (6.3 mm height)
Contains 100 adhesive-backed insulated spacers designed to adhere to PCB surfaces. Base size approx. 12.5 x 12.5 x 3 mm with a 4 mm support column diameter and a total height of 15 mm. The adhesive design helps keep spacers in place without drilling, while the buckle design ensures a secure clamp on the board during installation or removal. Ideal for quick, damage-free setups in DIY or professional contexts.
Marsui Sticky PCB Spacer 0.5″ (12.6 mm height)
Another 100-piece set with a larger height (0.5 inch) to accommodate thicker boards or stacked modules. It shares the same base dimensions and adhesive-fastening approach as the 0.25″ variant, promoting secure, damage-free mounting without tools. Suitable for PCBs inside enclosures, gaming devices, or industrial controllers where extra clearance is needed.
Marsrut 100 Pcs 3 mm Locking Sticky Spacers
These 3 mm nylon standoffs use a locking snap-in design with a foam-backed adhesive to secure PCBs firmly. The kit emphasizes safe installation with minimal risk of damage, eliminating the need for drills, punches, or screws. Particularly useful for compact assemblies where quick rework and reliability are important, such as retro gaming consoles or compact PC builds.
Kyuionty L Shape PCB Feet Kit
Contains 30 mounting feet and 32 screws with an L-shaped profile, designed to provide stable support for arcade boards and other circuit boards. Each foot measures 20 x 20 mm with a 0.98″ height profile, and mounting holes enable versatile placement. A practical option for arcade builds, game consoles, and similar hobby projects where discrete, durable feet are needed.
Zorveiio 100 Pcs PCB Feet Kit
Includes 100 lightweight L-type feet with 200 mounting screws. Each foot measures about 0.8″ x 0.8″ with a height of roughly 21.2 mm; designed to secure gaming boards, arcade motherboards, and video boards. The kit emphasizes modularity and replacement convenience for ongoing arcade or console projects, offering ample quantity for multiple builds or repairs.
LQ Industrial Sticky PCB Spacer Kit
25-piece set featuring white plastic spacers with back adhesive for stable fixing and a smooth, wear-resistant surface. The design emphasizes long service life and stable fixation on circuit boards, making it suitable for general electronics assembly, PCBs, and fixed stacking applications where a clean adhesive solution is preferred.
Buying Guide: Key Purchase Considerations
- Material and insulation: Most recommended spacers are nylon or other insulating plastics to prevent electrical shorts and resist corrosion. Consider environments with moisture or chemical exposure and choose materials with suitable dielectric properties.
- Mounting style: Adhesive-backed spacers offer quick, drill-free installations for lightweight boards, while mechanical spacers (screw-in or screw-on feet) provide durable, reusable fixes for heavier assemblies. Evaluate whether you need easy rework or long-term stability.
- Height and footprint: Determine the required clearance to accommodate connectors, heat dissipation, or cable routing. Spacers range from a few millimeters to over 20 mm in height; feet typically offer fixed footprints for stable mounting.
- Compatibility: Check screw size (e.g., M3) and hole spacing to ensure compatibility with your PCB layout and enclosure. L-shaped feet often come in standardized footprints suited for arcade or hobby boards.
- Adhesive quality: For sticky spacers, adhesive strength and residue behavior matter for removable vs permanent applications. Look for foam-backed or buckle designs that minimize damage during removal.
- Quantity vs use-case: Kits with many pieces support bulk projects or repairs, but ensure the package matches your typical project size to avoid excess. For hobbyists, smaller, versatile sets may be more practical.
- Application safety: Ensure non-conductive materials are used around high-voltage areas and that mounting does not compromise heat dissipation or airflow within enclosures.
- Replacement parts: In gaming or arcade builds, having a steady supply of feet and spacers helps with replacements and upgrades without downtime.
