The 1/2″ DTI DuraSquirt Squirter Washer offers a fast, visual, and reliable method for ensuring proper bolt tension in structural connections. Designed to meet ASTM F959 standards, this washer features a built-in silicone indicator that emits a visible squirt of orange when the proper load is achieved. It’s an ideal solution for steel erectors and inspectors seeking dependable tension control without the need for torque wrenches or tensioning tools.

What sets the DuraSquirt apart from standard squirter washers is its high-visibility, extended-extrusion silicone compound, which performs more consistently across a wider range of field conditions. It reduces the risk of false reads and missed indications, especially on complex or overhead installations.

Manufactured from durable steel and mechanically galvanized for enhanced corrosion resistance, this washer is perfect for outdoor or exposed structural applications. Its design simplifies verification of proper bolt installation in bridges, buildings, and other critical infrastructure projects.
