Rivetking. 25N75RC93P Solid Rivet 1/4 in Countersunk Stainless

Product Description

The RIVETKING. 25N75RC93P is a solid rivet designed for permanent mechanical fastening in structural and general fabrication applications. It features a 1/4 inch body diameter and a 3/4 inch length under head, with a 90-degree countersunk head profile that sits flush with the mating surface after installation. Constructed from grade 18-8 stainless steel with an uncoated finish, it delivers corrosion resistance suitable for environments where bare metal fasteners are required. This rivet is installed by licensed tradespeople and fabricators working in HVAC, plumbing support structures, electrical enclosures, and general sheet metal assemblies.

This solid rivet is suited for residential and light commercial applications where a flush, countersunk fastener is needed. The 90-degree countersunk head angle is compatible with standard countersunk pilot holes and is commonly used in sheet metal panels, brackets, access doors, and enclosure fabrication. The 18-8 stainless steel construction makes it a practical choice in mildly corrosive or moisture-exposed environments typical of mechanical rooms and outdoor equipment installations.

Key Features

• 1/4 inch body diameter for standard countersunk pilot hole sizing
• 3/4 inch length under head for typical sheet metal and light structural stack-ups
• 90-degree countersunk head profile installs flush with the work surface
• Grade 18-8 stainless steel construction provides corrosion resistance
• Uncoated finish - no added plating or treatment that could affect fit or conductivity
• Does not meet military specifications - suited for commercial and industrial use

Compatibility

Designed as a standard solid rivet replacement for countersunk fastener applications requiring a 1/4 inch body diameter and 90-degree head angle in sheet metal, enclosure, and bracket fabrication work.

Installation Notes

Solid rivets require a rivet set and bucking bar or a pneumatic riveting hammer for proper installation. Power down and de-energize any electrical enclosure or panel before fastening work begins. Ensure the countersunk hole is properly chamfered to match the 90-degree head angle before driving the rivet to avoid surface deformation. Follow applicable structural or sheet metal fabrication standards for hole sizing and rivet spacing.
