Stanley PBA6 Aluminum Rivet Backup Plates 3/16 in 30 Pack

Product Description

The STANLEY PBA6 is a pack of 30 aluminum backup plates designed for use with 3/16-inch blind rivets. Backup plates distribute the clamping load of a rivet across a wider surface area, preventing pull-through on thin, soft, or fragile base materials. Each plate sits on the blind side of the joint, behind the rivet mandrel, and spreads force evenly as the rivet sets. At 0.05 pounds per pack, these lightweight aluminum plates are easy to handle and store. They are a standard consumable for sheet metal, HVAC ductwork, and general fabrication work where joint integrity on soft substrates is critical.

These backup plates are used wherever a 3/16-inch rivet must fasten into a material that cannot support the rivet head load alone — thin-gauge sheet metal, fiberglass panels, vinyl, plastic housings, and similar substrates. HVAC technicians use them when riveting duct panels or access doors. Sheet metal workers and general contractors reach for them on any application where pull-through is a concern. The 30-piece pack format suits job-site use and small-batch repairs without overstocking consumables.

Key Features

• Aluminum construction — lightweight, corrosion-resistant, and compatible with aluminum rivets
• Sized for 3/16-inch blind rivets — the most common rivet diameter in HVAC and sheet metal work
• Distributes clamping load to prevent rivet pull-through on thin or soft materials
• 30-piece pack quantity — practical for service calls and small fabrication jobs
• Consistent dimensions across the pack for repeatable, reliable joints

Compatibility

Designed for use with 3/16-inch blind rivets in standard rivet installation applications involving thin-gauge or soft substrate materials.

Installation Notes

Backup plates are installed by a sheet metal worker, HVAC technician, or general fabricator using standard hand or pneumatic rivet tools. Place the backup plate on the blind side of the workpiece before inserting the rivet through the assembly. Ensure the plate is seated flat against the substrate so load is distributed evenly when the rivet is set. No power tools beyond the rivet gun are required, but eye protection should be worn during all riveting operations.
