Description:
The 5/16"-18 Steel Ribbed Rivet Nut (Part #055-206) provides a strong threaded insert for thin materials where access is limited to one side of the panel. Manufactured from durable steel and finished with yellow zinc plating, it offers excellent strength and corrosion resistance for automotive, fabrication, and industrial fastening applications.
The ribbed body design helps prevent spinning during installation, ensuring the rivet nut remains securely fixed in the mounting hole. Its open-end configuration allows for blind installation in sheet metal and similar materials, while the 5/16"-18 coarse thread provides a reliable anchor for bolts and machine screws.
With a low-profile head and wide head diameter, this rivet nut distributes load effectively across the surface for improved holding strength.
