⚠ VERIFY BEFORE ORDERING
Grade matters for torque spec — don't mix grades. A Grade 5 nut on a Grade 8 bolt weakens the joint.
Lock nuts, wing nuts, and castle nuts are NOT interchangeable with standard hex
✓ BROKER TIP
Match nut to bolt thread class and material. Stainless bolt + zinc nut = galvanic corrosion.
Always verify finish matches (plain, zinc, hot-dip galvanized)
