PBH Washer Mechanical Fastener (1,000 Pieces/Box)

THE BUILDER'S FIRST CHOICE FOR RELIABLE EIFS FASTENING

For over two decades, the PBH Washer has set the standard for durability and performance in EIFS applications. Its 2-inch diameter offers superior resistance to wind loads, delivering 25% more pullover strength than standard 1-3/4" washers. Designed with innovative features such as finger closures to prevent moisture penetration and a reinforced center hub to reduce overdriving, the PBH Washer ensures long-lasting, high-quality installations.
