For automated, high-speed assemblies, the Premium Lock structural blind rivet built for reliable clamping in thin or variable materials. A tapered, hole-seeking lead-in point supports fast, consistent installation. During setting, the Premium Lock forms a broad blind-side bulb that spreads clamp load over a larger bearing area, helping reduce pull-through in thin sheet and performing well in oversized, misaligned, or slotted holes.
 
Accufast stocks the Premium Lock in 400 series stainless steel for enhanced corrosion resistance. Its engineered bulbing system forms on the sheet line for superior blind-side strength, and positive mechanical pin retention helps maintain joint integrity in vibration-prone, structural applications.
