Load Spreading (LSR/LS) Rivets

POP Load Spreading (LSR/LS) Rivets 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.

This range of aluminium rivets with aluminium 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.

LSR BlindsideFeatures and Benefits:

  • Clamping loads spread over wide area, avoiding damage to vulnerable materials
  • Tolerance of oversized holes
  • Corrosion-resistant
  • High-strength aluminium 3.5% magnesium alloy
  • Set with standard POP hand riveting tools
  • Limited number of lengths needed because of wide grip range—up to 12.0mm

Load Spreading Rivets



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.
