Electro Hardware S301M17F16C Circuit Board Spacer Nylon

Product Description

The ELECTRO HARDWARE S301M17F16C is a round, female unthreaded circuit board spacer designed to maintain precise standoff distance between a PCB and a mounting surface or between stacked boards. Sized at 0.375 inches overall length with a 0.1875-inch outside diameter and a 0.089-inch inside diameter, this spacer accommodates a number 2 screw. It is molded from Nylon Grade 101 to MIL-P-17091B standards and supplied with an uncoated bright finish. Electronics assemblers and field technicians use these spacers during board mounting and PCB stack-up assembly where consistent spacing and electrical isolation are required.

This spacer is suited for use in residential and commercial electronic control assemblies, including circuit board mounting applications in HVAC control boards, low-voltage control panels, and general electronic enclosures. Its compact outside diameter of 0.1875 inches and short 0.375-inch body make it appropriate for tight PCB layouts. The female unthreaded design accepts a number 2 fastener passed through from the opposite side. Sold individually, with a minimum order quantity of 100 pieces per order.

Key Features

• Nylon Grade 101 construction meets MIL-P-17091B fastener standard for consistent material quality
• 0.375-inch overall length with a tight length tolerance of -0.005 to 0.005 inches for accurate board standoff
• 0.089-inch inside diameter with an inside diameter tolerance of 0.000 to 0.010 inches
• 0.1875-inch outside diameter in a round body profile fits compact PCB footprints
• Female unthreaded, uncoated bright finish — no threading required on the spacer body
• Sized for number 2 screw applications in inch-system assemblies

Compatibility

Designed as a standard-dimension PCB standoff spacer for number 2 screw applications in circuit board mounting assemblies conforming to inch-system dimensions.

Installation Notes

Installation is typically performed by electronics technicians or control board assemblers. Power down and de-energize the circuit board and enclosure fully before handling any PCB components. Use appropriately sized number 2 fasteners to avoid over-stressing the unthreaded nylon bore. Avoid applying excessive torque that could crack or deform the nylon body.
