Product Description
Metric A4 316 Marine Grade Stainless Steel Rivet Nuts
A4/316 stainless steel rivet nuts for creating internal threads in sheet material and hollow sections. These inserts can be installed from one side using a compatible rivet nut setting tool.
Featuring a flat head, open end and partially serrated body beneath the head, they provide a threaded attachment point where access behind the workpiece is restricted. The serrated section helps resist rotation within the prepared hole.
