Manufactured from brass and finished with a zinc plating that meets ASTM B633, QQ-B-626 Comp 22 Type 1 standards, this spacer measures 3\/16 inches overall length, 0.375 inches outside diameter, and 0.219 inches inside diameter. It is sized for a No. 12 screw and suits applications where dimensional consistency and corrosion resistance are both required. Electronics assemblers, control board technicians, and industrial equipment installers use this type of spacer during board mounting operations.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for use in residential and commercial electronics assemblies, HVAC control board installations, industrial panel builds, and any printed circuit board application requiring a female unthreaded standoff at a No. 12 screw size. The compact 3\/16-inch length makes it appropriate for low-profile PCB mounting scenarios where minimal board-to-chassis clearance is needed. Its brass construction with zinc plating provides reliable performance in environments where mild corrosion resistance is a priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale unthreaded design accepts a No. 12 screw for standard PCB mounting\u003c\/li\u003e\n  \u003cli\u003eBrass base material with zinc plating meeting ASTM B633 and QQ-B-626 Comp 22 Type 1\u003c\/li\u003e\n  \u003cli\u003eOverall length of 3\/16 inches (0.1875 inches) with a tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.219 inches with an ID tolerance of 0.000 to 0.010 inches for consistent fitment\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 0.375 inches for stable board support\u003c\/li\u003e\n  \u003cli\u003eRound body shape for uniform load distribution across mounting points\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install spacer for circuit board assemblies requiring a female unthreaded round standoff at No. 12 screw size in inch-measurement systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eElectronic assemblers and control board technicians should de-energize all equipment and discharge any stored electrical energy before handling or replacing circuit board spacers. Standard hand tools are sufficient for placement; no specialized torque equipment is required for unthreaded spacers of this type. Verify inside diameter clearance against the fastener shank before final assembly to ensure proper fitment within the stated ID tolerance range.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASTM B633, QQ-B-626 Comp 22 Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: No. 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Female Unthreaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.219 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ELECTRO HARDWARE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: S1059-M01-F21-J\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743342952754,"sku":"S1059-M01-F21-J","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_d5965a59-6185-486e-bad1-1c793a3ae311.jpg?v=1788845887","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s1059-m01-f21-j-circuit-board-spacer-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
