ASTM F3111

ASTM F3111 — Heavy Hex structural assemblies

Very-high-strength bolt, nut and washer assemblies, handled through a specification distinct from F3125.

Send your specification

A complete assembly, not a generic bolt

Identify the entire system: bolt, nut, washers, dimensions, finish, equipment and installation procedure. Components with the same diameter are not automatically interchangeable.

Data required for supply

Technical fieldRequirement
Rm min.200 ksi
ConfigurationHeavy Hex
DimensionsDiameter, length and grip range of the selected system
InstallationInstructions and checks for the specific assembly

Do not infer equivalence between standards from tensile strength in ksi alone. Check the standard and proposed system for temperature, exposure and outdoor-use limitations.

Specify the complete system

F3111 covers Heavy Hex assemblies with a minimum tensile strength of 200 ksi. Selection requires review of dimensions, installation, tests and documentation.

Send project requirements and conditions

Dueemme assesses sourcing against the project specification, without treating generic components as substitutes for the assembly. Include installation provisions and inspection requirements.

Service environment

F3111 restricts the permitted service environments. It must not be extended automatically to uncovered exterior structures or highly corrosive environments. Provide project conditions for application review.
