Washers to Suit all Bolts and Screws

Orange Silicone

When installed the silicone becomes fully cured omitting a powdered textured, this powered remains visible on the steel structure for several years. Simple and easy to include within the bolt assembly, upon installation or inspection the minium tension achieved can be observed. The silicone media in the DuraSquirt® DTI have been improved to withstand the elements of wind, heavy rain, and extreme enviromental temperatures.

AS1252

Squirter DTIs can be used with structural bolt assemblies that conform to AS1252 to aid in quickly identifying bolts that have not been tension correctly.

Technical Info

Material: ASTM F959M / Class 8.8
Dimensions: Confrom to ASME B18.2.6M
Coating: Mechanical Galvanised to ASTM B695 class 55
Heat Treatment: Through-hardening to a maximum hardness of HRC37

*Minimum bolt tension as per AS4100

Installation Method

The recommended installation is to position the DTI washer at the nut end of the assembly with the orange Squirt™ material facing towards the steel surface – seen in method A below. The assembly can then be tightened from the nut.

It is good practice to store all bolt hardware away from the elements prior to installation, preventing corrosion will reduce the effort required to tension bolts properly. The bolt threads and washer face of the hex nut can be lubricated to improve installation by reducing friction.

The hole detail in the steel work is critical to the bolt assembly and connection.
