Internal Threaded Bolt Hexagon Head Hex Body Galvanized

Internal threaded bolt means the bolt just like the nut which does have the internal thread but external thread. Internally threaded bolt usually used on where there is an external thread part that we can not reach, an internal threaded bolt is just fits the hole perfectly. Ever Hardware provides custom-made fasteners and customizable packaging.

In mechanical design, the prototypical “male” component is a threaded bolt, but an alignment post, a mounting boss, or a sheet metal tab connector can also be considered as male. Correspondingly, a threaded nut, an alignment hole, a mounting recess, or sheet metal slot connector is considered to be female.
While some mechanical designs are “one-off” custom setups not intended to be repeated, there is an entire fastener industry devoted to manufacturing mass-produced or semi-custom components. To avoid unnecessary confusion, conventional definitions of fastener gender have been defined and agreed upon.

A bolt is a form of threaded fastener with an external male thread. Bolts are thus closely related to, and often confused with, screws.
The distinction between a bolt and a screw is unclear and commonly misunderstood. There are several practical differences, but most have some degree of overlap between bolts and screws.
