Applied Bolting WDSTGM16 M16 Squirter DTI Washer, Class 8.8, Mechanical Galvanised

This page lists 3 sizes of the Applied Bolting Squirter DTI (direct tension indicator) washer, Class 8.8, mechanical galvanised: M16, M27 and 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 8.8 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 M16 x 36 x 3.4mm). The description does not label them, so check the outside diameter and thickness you need against Applied Bolting data.

Outside diameter, inside diameter, thickness and number of bumps are shown for M16, where published data exists for the same part (manufacturer-stated).

Pack quantity changes with size: pack of 100 for M16; pack of 50 for M27 and M36.

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