SEMI-HEX
RIVET NUT SEMI HEX LARGE FLANGE (LF)
📌 Overview
The Stainless Steel Semi Hex Rivet Nut with Large Flange is a versatile blind fastener designed to create strong, load-bearing threads in thin materials such as sheet metal, tubes, and hollow sections.
The semi-hexagonal body provides improved anti-rotation performance, while still accommodating round holes during installation. The large flange design distributes load over a wider surface area, increasing pull-out strength and preventing fastener pull-through—ideal for softer or oversized materials.
Manufactured using SS304 (A2) and SS316 (A4) stainless steel, these rivet nuts provide exceptional corrosion resistance, making them suitable for industrial, automotive, marine, and outdoor applications.

RIVET NUT SEMI HEX REDUCED COUNTERSUNK (RCSK)
📌 Overview
The Stainless Steel Semi Hex Rivet Nut with Reduced Countersunk Head is a premium blind fastening solution designed to provide strong, load-bearing threads in thin materials such as sheet metal, tubes, and hollow profiles.
Its semi-hexagonal body offers enhanced anti-rotation performance, gripping the material better than round body rivet nuts, while still allowing installation into standard round holes. The reduced countersunk head provides a low-profile, near-flush finish, ideal for applications requiring clean aesthetics or minimal protrusion.
Made from SS304 (A2) and SS316 (A4) stainless steel, these rivet nuts deliver superior corrosion resistance and durability, making them suitable for automotive, marine, electrical, industrial, and outdoor applications.
