Rivetking FBF43/P100 Open End Blind Rivet Size 42 100-pack

Product Description

The RIVETKING FBF43/P100 is a Size 42 open end blind rivet with a dome head, sold in a 100-piece pack. The body and mandrel are both 18-8 stainless steel, making this fastener well suited for corrosive or high-moisture environments. Body diameter is 0.125 inches with a grip range of 0.126 to 0.1875 inches, accepting a hole diameter between 0.129 and 0.133 inches. Tensile strength is rated at 530 pounds and shear strength at 420 pounds. Licensed fastener technicians, sheet metal workers, and maintenance mechanics working in food service, marine, or outdoor structural applications will find this rivet a dependable stainless option.

This rivet is used wherever a blind installation is required - meaning access is available from only one side of the workpiece. Typical applications include HVAC ductwork, enclosures, marine hardware, and stainless or dissimilar-metal assemblies where galvanic corrosion resistance is critical. The 18-8 stainless grade on both body and mandrel reduces the risk of mandrel-stem rust bleeding onto finished surfaces after installation, a common issue with carbon-steel mandrel rivets.

Installation Notes

Installation is performed by a sheet metal worker, HVAC technician, or maintenance mechanic using a manual or powered rivet gun. Drill a clean hole of 0.129 to 0.133 inches using a No. 30 drill bit and deburr the hole before inserting the rivet. Insert the rivet body fully into the hole before actuating the tool; do not partially seat the body and then pull, as this can cause a deformed head. Verify material stack-up is within the 0.126 to 0.1875 inch grip range before selecting this rivet length.
