Portland Bolt

Ensuring proper bolt tension in structural connections isn’t optional. It’s critical.

That’s where Squirter® DTI washers from Applied Bolting Technology come in.

These load-indicating washers provide visual confirmation of bolt tension. As the bolt is tightened,DuraSquirt® formula is expelled from the washer at a calibrated load, giving installers and inspectors immediate verification that the correct tension has been achieved.

No guesswork. No relying solely on torque charts.

Why they matter:
• Direct, visual tension verification
• Faster installation and inspection
• Reduced risk of under- or over-tightening
• Increased confidence in structural connections

And when you source them through Portland Bolt, you’re not just buying a component. You’re getting a complete solution.

We supply DTI washers alongside:
• Structural bolts (F3125 Grades A325 and A490)
• Nuts and hardened washers

Plus, with distribution on both coasts, we offer two-day shipping to most of the U.S., helping keep projects moving when timelines are tight.

Better compatibility. Faster delivery.
