Structural Fasteners

Bolts, Nuts and Washers for use with Structural Steel

Structural Fasteners are strong heavy duty fasteners that are typically used for creating structures through steel to steel structural connections such as buildings and bridges. They are often applied alongside other structural fasteners to metal beams and girders. A325, A563. and F436 Structural fasteners are all compatible with each other and it is advised to only use structural fasteners with other structural fasteners.

A563 Heavy Hex Nuts

Structural A563 Heavy Hex Finish Nuts, also known as A563 Heavy Hex Nuts. Heavy hex finish nuts, also known as heavy hex finished nuts, heavy hex nuts, and finish heavy hex, are used for many fastening applications. Heavy hex finish nuts are often used with bolts when a heavier, stronger and thicker nut is needed, often for strength or a thicker finished look.

F436 Flat Washers

A Structural F436 flat washer is a round outer diameter thin plate with a center hole (inner diameter) punched to the size of the bolt or screw size. Flat washers are normally used to distribute loads of threaded bolts, screws and nuts evenly as the fastener is tightened.

Structural Blind / POP Rivets

Structural Rivets, also known as interlock rivets in stainless steel with a stainless steel mandrel. Interlock pop rivets create a stronger assembly than standard stainless steel pop rivets, because of the amount of force that they generate. Domed head blind rivets in this selection are commonly referred to as both Interlock and Structural Rivets.
