Hex socket head cap screw(Nissan Neji(Full thread(Coarse Stainless steel Unplated 10X50X50 Pitch 1.5

This is a bolt with a cylindrical head featuring a hexagonal socket.
A hex key (Allen wrench) is used for tightening. Although classified as a bolt, it is most commonly used without a nut.
It is also known as a cap screw or socket screw. Claw spanners and wrenches used to tighten hex bolts require clearance space around the fastener, whereas a hex key requires no such clearance.
For this reason, hex socket head cap screws enable work in confined spaces and contribute to more compact machine designs.
Their appearance has also led to increasing use in decorative applications.
