A325 Structural Bolts

When your connection has to carry the load, step up to A325 Type 1 (USS) structural bolts. You get ASTM compliance and full traceability for steel jobs where specs matter, with strength comparable to SAE Grade 5. Choose plain for controlled indoor builds or hot-dip galvanized for outdoor corrosion resistance. Pair with 2H, Grade DH or Grade C hex nuts.
