Rivetking. 25N50RRDSP Round Head Solid Rivet 0.25 in Steel

Product Description

The RIVETKING. 25N50RRDSP is a round head solid rivet made from uncoated steel, intended for permanent mechanical fastening in light to medium industrial and structural assembly applications. With a body diameter of 0.25 inches and a length under head of 0.5 inches, this rivet is sized for close-tolerance through-hole installations where a flush, driven head is not required. The round head profile distributes clamping load across the material surface. Machinists, fabricators, maintenance technicians, and assembly workers install solid rivets using a rivet set and bucking bar or pneumatic rivet gun.

This solid rivet is suited for general-purpose metal fabrication, machinery assembly, bracket attachment, and sheet metal joining where a permanent, non-removable fastener is needed. The uncoated steel construction makes it appropriate for interior, protected, or painted assemblies where corrosion exposure is minimal. It is commonly used in manufacturing, HVAC ductwork framing, electrical enclosure assembly, and general sheet metal work. The single-piece solid body provides consistent shear and tensile performance after proper setting.

Key Features

• 0.25 inch body diameter for standard close-tolerance through-hole fitment
• 0.5 inch length under head accommodates typical single or double sheet stack-ups
• Round head profile distributes clamping load over the joined material surface
• Uncoated steel construction suitable for protected interior assemblies
• Solid one-piece body provides permanent, non-removable fastening after setting

Compatibility

Designed as a general-purpose solid rivet for use in standard through-hole applications requiring a 0.25 inch diameter round head steel fastener in light to medium fabrication assemblies.

Installation Notes

Solid rivets are installed by licensed machinists, fabricators, or assembly technicians using a rivet set, bucking bar, and hammer or pneumatic rivet gun. Ensure the through-hole diameter is drilled to the correct tolerance for the 0.25 inch body before installation. Always secure or support the workpiece to prevent movement during bucking. Refer to applicable fastener standards and facility safety protocols when selecting tooling and setting force.
