BOLTS:
- 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
WASHERS:
- ASTM F436 Flat Washers
- Hardened Steel Washers
- ASTM F959 Direct Tension Indicators (DTIs)
- Raised arches, or “bumps,” on washers 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 and DuraSquirt® DTIs)
- Like standard DTIs, with the addition of orange silicone that provides a visual indicator of correct tensioning—enabling quicker installation and inspection
- Nuts
- A563 Grade DH Heavy Hex Nuts
- Carbon Steel Nuts
- A194 Grade 2H Heavy Hex Nuts (acceptable substitute for A563 Grade DH)
- Carbon Steel Nuts for Bolts for High Pressure or High Temperature Service
- A563 Grade DH Heavy Hex Nuts
