1" Conquest DTI Flat Washer - Plain Engineered for heavy-duty structural bolts, the 1" Conquest DTI flat washer offers precise preload confirmation using compression-based feedback. Designed with raised indicators that collapse as bolt tension increases, it ensures your connections meet the exact requirements of ASTM F959. The plain steel finish supports installations where external protection is handled via coatings or environmental control. Always verify DTI compression with a feeler gauge or approved inspection method before final sign-off. 1" DTI Washer – Large Bolt Tensioning Made Verifiable This washer ensures your largest connections are safely and accurately fastened. It’s built for use in major infrastructure projects where bolt failure is not an option. Key Features Compression-Based Indicators: Visual and tactile confirmation of proper bolt preload.
