Product Introduction

This blind rivet combines a tubular stainless sleeve, low-profile flange head and central pull mandrel. A compatible riveting tool draws the mandrel to expand the concealed end of the sleeve, clamping overlapping sheet-metal parts without rear access. The compact head suits trims, closures and light-gauge cleanroom fabrications where exposed fasteners should remain neat and easy to wipe.

Key Features

Blind installation secures overlapping components when the rear face cannot be reached.

Stainless construction supports corrosion resistance in routinely cleaned interior environments.

The formed rear bulb spreads clamping force across thin sheet instead of relying on cut threads.

A low domed head creates a compact exposed profile on trims and closures.

Customer Product Concerns

Thin cleanroom sheet-metal parts often require a permanent joint even when finished panels block access to the rear surface.

Installers cannot hold a nut behind a closed panel or trim cavity.Blind-rivet setting forms the concealed retaining bulb entirely from the accessible face.

Ordinary carbon-steel fasteners can stain or corrode after repeated cleaning.A stainless sleeve and compatible mandrel provide improved corrosion resistance for controlled interiors.

Oversized fasteners distort light-gauge sheet around the fixing point.Correct rivet diameter, grip range and drilled-hole tolerance distribute clamp load without excessive tightening torque.

Protruding hardware creates an untidy, difficult-to-wipe surface.The compact domed flange leaves a smooth exposed head after the mandrel breaks.
