Electro Hardware S1095-M07-F16-I Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1095-M07-F16-I is a round, female unthreaded circuit board spacer designed to create precise standoff clearance between a PCB and a mounting surface. Machined from 18-8 Grade 303 stainless steel to the QQ-S-763 fastener standard, it delivers corrosion resistance and dimensional stability in both indoor and light-exposure environments. The spacer accepts a No. 10 screw through its 0.194-inch inside diameter bore and measures 0.75 inches in overall length with a 0.375-inch outside diameter. An uncoated finish preserves the bare stainless surface and keeps tolerances tight for consistent board-to-board stacking height.

This spacer is suited for use in control board assemblies, relay panels, and electronic enclosures found in HVAC equipment, electrical panels, and similar trade applications. It is typically installed by HVAC technicians, electricians, and controls technicians when mounting or replacing circuit boards inside equipment cabinets. The female unthreaded design allows a No. 10 fastener to pass through freely, making it appropriate for through-bolt or standoff-stack configurations where adjustable clamping height is needed.

Key Features

• 18-8 Grade 303 stainless steel construction for corrosion resistance in demanding environments
• Meets QQ-S-763 fastener standard for dimensional and material compliance
• Female unthreaded bore sized for No. 10 screw clearance
• Round body with 0.375-inch OD for compact panel layouts
• Uncoated finish maintains precise tolerances for consistent stacking height
• Inside diameter tolerance of 0.000 to 0.010 inches and length tolerance of -0.005 to 0.005 inches

Compatibility

Designed as a standard No. 10 screw circuit board spacer for use in PCB mounting applications requiring a 0.75-inch standoff height in control boards and electronic enclosures.

Installation Notes

Installation should be performed by a qualified electrician or HVAC controls technician. Always de-energize the equipment and follow applicable NEC or equipment manufacturer lockout-tagout procedures before working on any control board assembly. Use a correctly sized No. 10 fastener and verify the mating board hole pattern before torquing hardware. Do not over-compress the spacer stack, as this can crack the PCB substrate or deform mounting bosses.
