Electro Hardware S1071-M01-F21-H Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1071-M01-F21-H is a round, female unthreaded circuit board spacer designed to create a fixed standoff between a PCB and a mounting surface or adjacent board. Machined from brass and finished with zinc plating per ASTM B633 and QQ-B-626 Comp 22 Type 1, this spacer provides corrosion resistance and reliable dimensional stability under repeated thermal cycling. It has an overall length of 0.375 inches, an inside diameter of 0.171 inches, and an outside diameter of 0.375 inches, sized to accept a No. 8 screw. HVAC control board assemblies, electrical enclosures, and pool equipment panels are common installation environments.

This spacer is suited for residential and light commercial applications wherever circuit boards require secure standoff mounting. It is installed by electricians, HVAC technicians, and electronics assembly professionals during control board replacement or panel assembly work. The female unthreaded body accepts a No. 8 fastener passed through from the board side, holding the PCB at a consistent height above the mounting plane to prevent short circuits and allow airflow beneath the board.

Key Features

• Brass construction with zinc-plated finish meets ASTM B633 and QQ-B-626 Comp 22 Type 1 standards
• Female unthreaded body accepts No. 8 screws for straightforward PCB standoff mounting
• Overall length of 0.375 inches with a tight length tolerance of -0.005 to 0.005 inches
• Inside diameter of 0.171 inches with an inside diameter tolerance of 0.000 to 0.010 inches
• Round body profile for consistent fitment in standard PCB standoff hole patterns
• Zinc plating provides corrosion resistance in enclosure and panel environments

Compatibility

Designed as an OEM-style replacement or assembly component for circuit board standoff applications requiring a No. 8 screw, 0.375-inch overall length, and 0.375-inch outside diameter in inch-measurement systems.

Installation Notes

Power down and de-energize the control board assembly and any associated equipment before removing or installing circuit board spacers. Use appropriate non-marring tools to seat the spacer without deforming the zinc-plated finish. Follow applicable NEC guidelines when working inside electrical enclosures. Verify spacer length and inside diameter match the existing standoff specification before installation to maintain proper PCB clearance.
