SEMI-HEX
RIVET NUT SEMI HEX LARGE FLANGE (LF)
📌 Overview
The Stainless Steel Semi-Hex Rivet Nut with Large Flange is a high-strength blind fastening solution designed to provide strong internal threads in thin or hollow materials such as sheet metal, tubes, and extrusions.
Its semi-hexagonal body offers excellent anti-rotation performance, gripping the material securely while allowing installation into standard round holes. The large flange increases bearing surface, distributing load more evenly and preventing pull-through in soft or thin materials.
Manufactured in SS304 (A2) and SS316 (A4) stainless steel, these rivet nuts provide superior corrosion resistance and long-term durability, making them suitable for automotive, marine, industrial, electrical, and outdoor applications.
