Rivetking. SBS66/P250 Dome Head Steel Blind Rivet 250pk

Product Description

The RIVETKING. SBS66/P250 is a Size 66 dome head, open end blind rivet designed for permanent fastening in applications where access is limited to one side of the workpiece. The rivet body is steel with a phosphate-finished steel mandrel. It features a 3/16 inch body diameter, a 3/8 inch dome head diameter, and a grip range of 0.251 inches to 3/8 inches. Length under head is 0.575 inches. Hole diameter range is 0.192 inches to 0.196 inches. Shear strength is rated at 540 pounds. This package contains 250 rivets. Licensed trades including HVAC installers, plumbers, electricians, and sheet metal workers use these fasteners in both new construction and service work.

Size 66 dome head blind rivets are used in light to medium structural and non-structural fastening tasks across HVAC ductwork, electrical enclosures, plumbing brackets, sheet metal panels, and general metal fabrication. The open end design allows the mandrel to pull through, expanding the rivet body and clamping the material. This style is appropriate for steel, aluminum, and similar substrate combinations where a flush, rounded head profile is acceptable on the accessible side.

Key Features

• Open end design for standard one-sided blind installation
• Dome head profile provides a smooth, low-profile finish on the accessible face

• Shear strength of 540 pounds per IFI 114 Grade 30 standards
• Grip range of 0.251 inches to 3/8 inches accommodates variable material stack thicknesses
• Package quantity of 250 rivets reduces per-job procurement frequency

Compatibility

Designed for use in any application requiring a 3/16 inch body diameter, open end blind rivet with a 0.192 inch to 0.196 inch hole diameter. Suitable for steel and compatible substrate materials in HVAC, electrical, plumbing, and general sheet metal fabrication work.

Installation Notes

Install using a standard rivet gun or pneumatic rivet tool rated for 3/16 inch body diameter rivets. Drill or punch the mating hole to a diameter between 0.192 inches and 0.196 inches before insertion. Ensure material stack thickness falls within the 0.251 inch to 3/8 inch grip range before selecting this rivet for a given application. The mandrel stem will break off at the set point during installation and should be collected and disposed of properly.
