The M3x30mm Hexagonal Spacer Standoff (Male-Female) is a precision-engineered hardware component designed for secure mechanical spacing and alignment in electronic assemblies. This standoff features a hexagonal body for easy installation using standard tools, with a male M3 thread on one end and a female M3 threaded socket on the opposite end. Ideal for mounting PCBs, securing enclosures, or creating modular stackable systems in IoT, robotics, and embedded electronics projects. Constructed from high-strength brass or aluminum (material may vary), this spacer ensures excellent conductivity (if metal) and durability under mechanical stress. The 30mm length provides optimal clearance for heat dissipation, cable routing, or component isolation. Its standardized M3 threading ensures broad compatibility with most development boards, sensor modules, and custom PCBs commonly used in maker and industrial applications. Designed for reliability and repeatability, this standoff is suitable for both prototyping and production environments. Whether used in Raspberry Pi enclosures, drone frames, or industrial control panels, it delivers consistent performance and structural integrity. A must-have accessory for engineers, makers, and procurement officers sourcing dependable mounting hardware.

Openbuilds M5 Flat T Nut for 20mm Aluminium Profile Tee nuts is an integral part of any for openbuild, adds flexibility and extends tuning; Easy to install to make the system more solid; fast and secure the connection along the length of the V-groove or c-beam linear guide; It has customized angular angle for smooth sliding. Install with M5 or 4mm fixing screws. Compatible with 10mm size slots. The M3/M4/M5 Tee Nuts are designed and custom-made with angled corners to allow for a smooth transition when sliding into V-Slot Linear Rail. You can use these Tee Nuts just like you would a Double Tee Nut to make any connection that you need anywhere along the length of the V-Slot Linear rail track. These Tee Nuts are reversible. You can flip them upside down if you need more threading.
