Folds into three legs to grip soft, brittle and thin materials.

Section: Blind rivets

Overview

Trifold rivets are made for soft, brittle or thin materials. On the blind side the body splits into three legs that spread the clamping force over a larger area.

This reduces the risk of cracking the parts and copes with irregular or oversized holes. Available with coloured heads.
