Description
S-5! Bulb Tite® Rivet 9/32″ × 3/8″ 1558936
The S-5! / SFS 9/32″ Bulb-Tite® blind rivet (part 1558936, code RV6603-9-6W) is a structural, weather-resistant fastener ideal for securing S-5! brackets to thin-gauge metal roofing and for repairing over-torqued screw holes. Its bulbing legs create a large backside footprint for high shear/tensile capacity in thin sheet applications.
Key Benefits
Wide Grip Range: 0.032″–0.375″ (≈ 1/32″ to 3/8″) covers common roof sheet stacks and sealant washers.
Structural Performance: Rated to ~1,100 lbf tensile and ~1,400 lbf shear.
Vibration & Weather Resistant: Tamper-resistant design that won’t loosen under fatigue.
Field-Proven with S-5! Brackets: Recommended for securing S-5! brackets or repairing stripped holes.
Special Technology
Bulb-Forming Legs: Large backside bearing area protects thin metal skins and improves pull-through resistance.
Aluminum/Aluminum Construction: Corrosion-resistant body/mandrel combo suited to metal roof assemblies.
Controlled Installation: Uses a special 9/32″ Bulb-Tite® nosepiece (P/N 1434989) for consistent set.
Warranty
Manufacturer’s standard fastener warranty (SFS/S-5!).
Best Uses
Metal Roof Attachments: Mounting S-5! brackets/clamps and PVKIT® components to thin-gauge panels.
Repair & Retrofit: Replacing over-torqued screws in existing holes on exposed-fastener panels.
