    • ASTM A325 Heavy Hex Bolts


      Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength

    • ASTM A490 Heavy Hex Bolts


      Structural Bolts, Alloy Steel, Heat Treated, 150 ksi Minimum Tensile Strength

    • ASTM F436 Flat Washers


      Hardened Steel Washers

    • ASTM F959 Direct Tension Indicators (DTIs)


      Raised arches, or "bumps", on washer that deform when a bolt is tightened sufficiently. Better than the Turn-of-Nut method for bolt tightening. Use a feeler gauge to check for proper tensioning.

    • ASTM F959 Squirter Direct Tension Indicators (Squirter DTIs)


      Like standard DTIs, with the addition of orange Silicone that provides a visual indicator of correct tensioning, enabling quicker installation and inspection.
