T-lock rivets are structural peeled blind rivets designed for improved support in brittle, soft or ductile materials. The mandrel of t-lock rivets is designed to split the end of the rivet body into four separate legs to create a large blindside bearing surface. The legs clamp the material tightly and spread the load over a wide area. This significantly reduces the risk of the rivet breaking through brittle material or sinking into soft materials. Peel rivets are ideal for use in wood, insulation, plasterboard and plastic materials.
