Tri-fold rivet are designed especially for plastics and other brittle or soft materials, with a secondary head that forms large "folds". This provides a larger bearing surface that resists the pull-through or cracking that can occur in some materials with a standard rivet.
LSR rivets are perfectly suited to plastics, wood, GRP, laminates, and thin-gauge materials. LSR rivets have an important role to play in applications including the assembly of mobile homes and park homes, installation of plastic-framed windows, and the manufacture of plywood furniture or timber products such as trailers.
This rivet should be selected whenever the materials to be fastened are so soft or brittle that the tensile force exerted by a conventional rivet would cause damage. Alternatively, use the soft-set rivet where a smaller secondary head is desired.
tri-fold rivets are designed for those instances when using a backup washer is difficult or impossible. These rivets separate into three legs to spread the clamping force over a larger area, similar to a backup washer. Allstar Performance tri-fold rivets are available in a variety of colors and head sizes.
Tri-fold rivet forms three large folded legs that distribute the fastener's clamp-load over a large blind side head formation. This feature provides maximum support for brittle, soft or ductile material applications, and when used with oversized or irregularly shaped holes. Tri-fold rivet is used in automotive applications such as plastic body panels, trim and interior components.
This range of aluminum rivets with aluminum mandrels is designed to offer two particular advantages in joining soft, friable, or brittle materials. Its controlled setting gives outstanding reliability and produces a neat, uniform appearance.
