Product Description

Carbon Steel ASTM F959 DTI Squirter Steel Flat Washer

 

Specification

 

These washers release an orange dye when tightened. They’re designed for use with A325 A490 structural screws, studs, and nuts and are often used for construction and exterior building applications.

ASTM F959 covers the requirements for compressible washer type direct tension indicators in diameters ranging from 1/2” to 1-1/2” inclusive. These washers are capable of indicating the achievement of a specified minimum bolt tension. They are available in two grades for use with A325 and A490 structural bolts and are also available in a weathering steel option for both grades.
