Rivetking 18N37RC9SP Countersunk Solid Rivet 3/16 in Steel

Product Description

The RIVETKING 18N37RC9SP is a countersunk solid rivet designed for permanent fastening applications in metal fabrication, HVAC equipment assembly, electrical enclosures, and general mechanical construction. The body diameter measures 3/16 inches with a length under head of 3/8 inches and a 90-degree countersunk head angle. Made from steel, this solid rivet is driven and set using standard rivet sets and hammers or pneumatic riveting equipment. Solid rivets provide a strong, vibration-resistant mechanical joint and are preferred in assemblies where a flush surface finish is required on the face side of the workpiece.

This rivet is suited for trade and industrial applications where a flush fastening profile is needed on structural panels, equipment housings, ductwork brackets, and similar assemblies. The 90-degree countersunk head seats flush with the material surface when installed into a properly prepared countersunk hole, making it appropriate for assemblies where protrusion would interfere with adjacent components or finished surfaces.

Key Features

• 3/16 inch body diameter for standard medium-duty solid rivet applications
• 3/8 inch length under head accommodates typical sheet and panel stack thicknesses
• 90-degree countersunk head angle provides a flush, low-profile installed finish
• Steel construction delivers reliable shear and tensile strength in mechanical assemblies
• Solid rivet design creates a permanent, vibration-resistant joint

Compatibility

Designed as an OEM-style solid rivet replacement for general mechanical, HVAC, electrical enclosure, and fabrication assemblies requiring a 3/16 inch countersunk steel rivet.

Installation Notes

Installation should be performed by a qualified mechanic, fabricator, or trade technician using a properly sized rivet set and bucking bar or pneumatic rivet hammer. The receiving material must be drilled and, where required, countersunk to the correct angle and diameter before installation. Ensure the workpiece is securely clamped and power to any associated electrical assembly is disconnected before beginning fastener work. Do not reuse solid rivets once set; removal requires drilling out the existing fastener.
