Detail & Specs
This rounded head style bolt + nut set provides a complete fastening solution that can also act as a male / female thread gauge when determining the pitch of an unidentified thread pattern. Class 5.8 steel is a low to medium strength carbon steel.
Hexagonal head bolts are one of the most commonly used fasteners, available in full thread or partial thread configurations.
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.
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.
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
