Applied Bolting (DTI Washer) Selection — Quick Reference
Applied Bolting = DIRECT TENSION INDICATING (DTI) "Squirter" washers for STRUCTURAL STEEL construction. Visible silicone squirt confirms correct bolt tension WITHOUT torque wrench guesswork. Match to bolt spec for ASTM F959 / ISO 7250 compliance.
| Applied Bolting Product | Best For |
|---|---|
| Squirter DTI Washer (Various Grades) | Structural steel + critical bolted joint |
| F1852 / F2280 Compatible | ASTM structural bolt sizes |
| Common Bolt Diameters (M16-M30+) | Match to structural bolt spec |
| Galvanised Finish | Outdoor + corrosion-resistant |
Why DTI: Visible silicone "squirt" CONFIRMS correct bolt tension applied — eliminates guesswork + reduces inspection time + improves joint reliability. Eliminates need for calibrated torque wrench. Structural standards compliance. Brand: Applied Bolting. Companion: fasteners, structural bolts, torque wrenches.
Applied Bolting Squirter DTI Washers at AIMS Industrial
Applied Bolting Technology manufactures Direct Tension Indicating (DTI) fasteners for structural steel construction. Their Squirter DTI Washers provide a clear visual confirmation that bolts have reached the correct clamp force — small squirts of orange silicone appear around the washer perimeter when the target tension is achieved, eliminating guesswork on critical connections.
Squirter DTI Washers in Stock
AIMS Industrial stocks Applied Bolting Squirter DTI Washers across multiple grades and finishes. Available options include:
- Class 8.8 — Mechanical Galvanised
- Class 10.9 — Plain/Black and Mechanical Galvanised

People Also Ask — APPLIED BOLTING
Q: What does the orange silicone squirt on an Applied Bolting Squirter DTI washer actually indicate?
Small squirts of orange silicone appear around the washer's perimeter once the bolt has reached its target clamp force — a direct visual confirmation of correct tension on a critical connection, without needing to interpret a gap or gauge reading.
Q: What ASTM standards do Applied Bolting Squirter DTI washers comply with?
They're matched to bolt specification for ASTM F959 and ISO 7250 compliance, and are compatible with F1852 and F2280 structural bolt sizing.
Q: What grades and finishes are Applied Bolting Squirter DTI washers available in at AIMS?
AIMS stocks Class 8.8 in mechanical galvanised, Class 10.9 in both plain/black and mechanical galvanised, Grade 5 in mechanical galvanised, and metric load indicator washers.
Q: What bolt diameter range do Applied Bolting Squirter DTI washers cover?
They're available for common structural bolt diameters from M16 up to M30 and beyond, matched to the structural bolt spec being used.
Q: Why would a construction project specify DTI washers instead of relying on a torque wrench or turn-of-nut method?
DTI washers are widely specified on infrastructure, construction and industrial projects where bolt tension verification is critical, because they remove the need for a calibrated torque wrench or turn-of-nut technique and instead give a direct visual confirmation that the connection has been installed correctly.
