With a 3mm diameter and standard 0.5mm thread pitch, they provide a reliable hold without excessive bulk. This set includes assorted lengths and matching hex nuts, making it perfect for everything from sensor modules to robotics frames.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003eM3 (3mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThread Pitch\u003c\/td\u003e\n\u003ctd\u003e0.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eZinc-plated steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHead Type\u003c\/td\u003e\n\u003ctd\u003eHex socket cap\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLengths Included\u003c\/td\u003e\n\u003ctd\u003e10mm, 12mm, 16mm, 20mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e50 bolts, 50 nuts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSecurely mount Arduino, Raspberry Pi, and other development boards into enclosures\u003c\/li\u003e\n\u003cli\u003eAssemble custom 3D printed cases for IoT sensors and controllers\u003c\/li\u003e\n\u003cli\u003eCreate sturdy PCB stack-ups with M3 standoffs for multi-board projects\u003c\/li\u003e\n\u003cli\u003eBuild robotics frames and brackets that require reliable, vibration-resistant fastening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThese bolts fit standard M3 clearance holes found on most microcontrollers, single-board computers, and expansion shields. They pair well with M3 standoffs (hex or round) and are compatible with common prototyping materials like acrylic, plywood, and 3D printed PLA\/ABS. Voltage and signal insulation is not affected, as they are purely mechanical.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eWhen fastening near PCB traces, slide a nylon washer under the bolt head to prevent accidental shorts. Always finger-tighten before final torque to avoid stripping threads—M3 threads are fine and can be damaged by overtightening, especially in plastic housings.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
