Applied Bolting WD10MM12 M12 Squirter DTI Washer, Class 10.9, Mechanical Galvanised

This page lists 6 sizes of the Applied Bolting Squirter DTI (direct tension indicator) washer, Class 10.9, mechanical galvanised: M12 to M36.

A Squirter DTI has a flexible silicone embedded in the depressions under its bumps, and the bolt is tightened until the calibrated amount of orange silicone appears from under the squirt locations (manufacturer-stated).

Applied Bolting describes Squirter DTIs as delivering visual verification of bolt tension (manufacturer-stated).

The Squirter DTI is listed as manufactured to ASTM F959M and designed for AS1252 structural bolting (manufacturer-stated).

Class 10.9 is the class named in the product description; the description does not say what the class refers to, so confirm the match with the bolt assembly you are using.

Mechanical galvanised is the finish named in the product description; no coating thickness is published here.

Each size is listed with three figures (for example M12 x 30.2 x 3mm). The description does not label them, so check the outside diameter and thickness you need against Applied Bolting data.

Pack quantity changes with size: pack of 100 for M12 to M24; pack of 50 for M30 and M36.

No tension, torque or load figures are published here. Follow Applied Bolting installation instructions and your project specification.
