Trifold Rivets

Three Folding Legs · Soft & Brittle Substrates • Ø d = 3.2 – 6.4 mm

Engineering Overview

Designed for the assembly of soft, brittle or thin materials. The trifold formation on the blind side applies the rivet's clamping force over an increased area, reducing the risk of cracking the parent material and compensating for irregular or oversized holes.
