Unlike micro rod, 3\/16 inch 6061 aluminum round bar has enough cross section to carry shear loads as a dowel or hinge pin, enough material to cut small external threads, and enough stiffness to stay straight as a standoff or small axle. The T6 temper keeps the part rigid and fatigue-resistant, while 6061's machining behavior stays clean and predictable on Swiss-type lathes, small CNC mills, and bench-top machines. That combination makes this range a favorite of fastener makers, electronics assemblers, and instrument builders.\u003c\/p\u003e\n\u003cp class=\"rk-sub\"\u003eCommon Applications\u003c\/p\u003e\n\u003cdiv class=\"rk-chips\"\u003e\n\u003cspan\u003eDowel \u0026amp; alignment pins\u003c\/span\u003e\u003cspan\u003eStandoffs \u0026amp; spacers\u003c\/span\u003e\u003cspan\u003eBolt \u0026amp; screw blanks\u003c\/span\u003e\u003cspan\u003eHinge pins\u003c\/span\u003e\u003cspan\u003eLinkages \u0026amp; pushrods\u003c\/span\u003e\u003cspan\u003eConnector pins\u003c\/span\u003e\u003cspan\u003eSmall appliance shafts\u003c\/span\u003e\u003cspan\u003eGuide \u0026amp; locator pins\u003c\/span\u003e\u003cspan\u003eRC \u0026amp; model parts\u003c\/span\u003e\u003cspan\u003eInstrument hardware\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cp class=\"rk-sub\"\u003eWhat These Rods Are Used For\u003c\/p\u003e\n\u003cdiv class=\"rk-box\"\u003e\n\u003cul class=\"rk-list\"\u003e\n\u003cli\u003eDowel and alignment pins that locate jigs, molds, and bolted assemblies\u003c\/li\u003e\n\u003cli\u003eStandoffs, spacers, and support posts in electronics and small enclosures\u003c\/li\u003e\n\u003cli\u003eBolt, screw, and threaded-stud blanks turned and threaded from solid\u003c\/li\u003e\n\u003cli\u003eHinge pins, cotter-style pins, and pivot rods for doors, lids, and levers\u003c\/li\u003e\n\u003cli\u003eSmall linkages, control rods, and actuator pushrods\u003c\/li\u003e\n\u003cli\u003eConnector and contact-pin stock for electrical and test equipment\u003c\/li\u003e\n\u003cli\u003eSmall axles in appliances, toys, printers, and precision instruments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cp class=\"rk-sub\"\u003eMaterial Behavior at This Size\u003c\/p\u003e\n\u003cp class=\"rk-p\"\u003e6061-T6 combines magnesium and silicon for strength with strong atmospheric and moisture corrosion resistance, so small pins and standoffs hold up inside outdoor equipment and marine-adjacent devices.
