High Tensile Hexagon Nuts
Hex nuts (also referred to as finished hex nuts) are available in ASTM A563-A, A194 and compatible with low carbon steel bolts such as ASTM A307, ASTM F1554 grade 36, SAE grade 2. SAEA Grade 5 and grade 8 nuts are also available in a finished pattern. Since hot-dip galvanising typically adds 2.2 to 5 mils of thickness to the threaded portion of a fastener, galvanised hex nuts are tapped oversize to compensate for the corrosion resistant coating on the bolts.
