Heavy Bolts
High Strength Heavy Hex Bolts for Steel Structures & Industrial Construction
VALTOR supplies high-strength heavy hex bolts for structural steel connections, industrial buildings and engineering projects. ASTM F3125 options, including commonly recognized A325 and A490 grades, are available in carbon steel and alloy steel with project-appropriate finishes.
Product Overview
Heavy hex bolts are high-strength structural fasteners mainly used for steel construction and industrial projects where reliable load-bearing connections are required.
Compared with standard hex bolts used for general mechanical fastening, heavy hex bolts feature a larger head size and bearing surface for structural applications requiring stronger clamping performance.
VALTOR supplies high strength carbon steel heavy bolts and alloy steel structural bolts with different grades, UNC thread specifications and surface treatments for construction and industrial requirements.
Common options include ASTM F3125 heavy bolts in the commonly recognized ASTM A325 and ASTM A490 structural grades, with hot dip galvanized, black oxide and plain finishes according to application conditions. Stainless steel is available only upon request.
