Electro Hardware S841-M07-F16-H Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S841-M07-F16-H is a round, female unthreaded circuit board spacer manufactured from 18-8 and 303 grade stainless steel to the QQ-S-763 fastener standard. It is sized for No. 8 screws, with a 1-inch overall length, a 0.171-inch inside diameter, and a 0.3125-inch outside diameter. This spacer is used to create a fixed standoff distance between a circuit board and a mounting surface, providing both physical separation and panel alignment. Electricians, electronics technicians, and control panel assemblers install this type of hardware during board mounting in enclosures, control systems, and equipment panels.

This spacer suits residential and commercial electrical, HVAC control boards, and industrial panel assemblies where a No. 8 fastener is the standard thread size. Its uncoated stainless steel construction makes it well suited for environments where corrosion resistance is a priority. The female unthreaded body accepts a No. 8 screw from either end to sandwich and secure the board at the specified standoff height. It is sold and packaged as a single piece.

Key Features

• 1-inch overall length provides consistent standoff height between board and mounting surface
• 0.171-inch inside diameter sized for No. 8 screw thread fitment
• 0.3125-inch (5/16 inch) outside diameter in a round body profile
• 18-8 and 303 grade stainless steel construction for corrosion resistance
• Female unthreaded design accepts No. 8 screws from both ends
• Meets QQ-S-763 fastener standard; uncoated finish

Compatibility

Designed as an OEM-style replacement or new-installation spacer for circuit board mounting applications requiring a No. 8 screw, 1-inch standoff height, and a 5/16-inch OD round body form factor.

Installation Notes

This spacer is typically installed by electricians or electronics technicians during control board mounting inside enclosures or equipment panels. De-energize all circuits and discharge any stored energy before working inside a panel. Use appropriately sized No. 8 fasteners and verify overall length against your board-to-panel clearance requirement before installation. Follow applicable NEC guidelines for enclosure and control board work.
