Detail & Specs
Class 8.8 metric hex bolts provide a medium strength, high tensile fastening solution. Pair with Class 8 or stronger nuts.
Hexagonal head bolts are one of the most commonly used fasteners, available in full thread or partial thread configurations.
Partially threaded hex bolts have an unthreaded length under the head that is stronger than the threaded portion of the bolt. The unthreaded / threaded length dimensions vary by specification.
Fully threaded hex bolts are often referred to as tap bolts, the entire length of the bolt is meant to engage with a tapped hole.
Hex bolts can be used with many different styles of locking and non-locking nuts, tightly clamping together whatever the bolt is being used to secure. A wrench is used to install and tighten hex bolts.
Also known as
Fine, extra fine or super fine thread hex cap screw, HHCS, hexagonal head screw, six sided head screw with machine thread, machine bolts.
To be used with locking or non-locking nuts or in a tapped hole.
