Built from Grade 2 steel with a zinc-plated finish, this spacer measures 0.375 inches overall length, 0.3125 inches outside diameter, and 0.141 inches inside diameter. It is sized for No. 6 screw applications and meets ASTM B633 and QQ-S-633 Type 1 finish standards. Licensed electronics assembly technicians, industrial maintenance professionals, and trade installers use these spacers when mounting control boards inside HVAC equipment, electrical panels, and other enclosures where precise board clearance is required.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for applications where a No. 6 fastener is used to secure a circuit board at a fixed standoff height of 0.375 inches. The round body profile and female unthreaded bore allow the fastener to pass through freely, making it a reliable choice for control board mounting in residential and light commercial HVAC units, electrical enclosures, and industrial control panels. The zinc-plated steel construction provides corrosion resistance appropriate for indoor service environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale unthreaded bore accepts No. 6 screws with 0.141 inches inside diameter\u003c\/li\u003e\n\u003cli\u003e0.375 inches overall length provides consistent PCB standoff height\u003c\/li\u003e\n\u003cli\u003e0.3125 inches outside diameter with round body for stable surface contact\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction meets ASTM B633 and QQ-S-633 Type 1 standards\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish for corrosion resistance in indoor enclosure environments\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance of 0.000 to 0.010 inches; length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service-stock spacer for circuit board mounting applications requiring a No. 6 screw, 0.375 inches standoff height, and a round female unthreaded body in steel construction.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed electricians, HVAC technicians, or electronics assembly professionals. Always de-energize and lockout the equipment before servicing any control board or electrical enclosure.
