Heavy Hex Nut, A563 A, Plain (Inch)
Heavy Hex Nuts A563 Grade A Plain are general-purpose, medium-strength fasteners manufactured in accordance with ASTM A563 specifications. These six-sided heavy-pattern nuts feature a larger width across flats and increased thickness compared to standard hex nuts, providing greater bearing surface and improved load distribution. The plain (uncoated) finish offers a natural steel surface suitable for indoor use, or for applications where additional coating or plating will be applied.
A563 Grade A Heavy Hex Nuts are commonly used in structural, construction, and machinery applications with bolts and threaded rods of compatible grades. Designed for reliable performance and easy assembly, they offer consistent strength and durability. The plain finish makes them an economical choice for non-corrosive environments or pre-treated fastening systems.
