Metric Hexagon Socket Cheese Head Screws
Internal hexagon bolt, also commonly known as internal hexagon screw or cylindrical head internal hexagon screw, is a type of fastener with a hexagonal head shape.
Appearance features:
The outer edge of the head of the hexagonal bolt is circular, and the middle is a concave hexagon. This design requires the use
of a special hexagonal wrench for tightening and disassembling.
Common types of hexagon socket bolts include cylindrical head, pan head, countersunk head, flat head, as well as special types
such as headless screws and stop screws.

Usage and advantages:
Hexagonal socket bolts are commonly used in machinery and have the advantages of being easy to tighten, disassemble, and less prone to slipping.
Its design enables effective fastening operations even in narrow or confined spaces.
Hexagonal bolts can also be countersunk and sunk into the interior of the workpiece, making the connection more delicate and aesthetically pleasing.
Material and strength grade:
There are various materials for hexagonal bolts, including stainless steel (such as SUS202, SUS304, SUS316, etc.) and iron 5.
Iron hexagon bolts are classified into strength grades of 4.8, 8.8, 10.9, 12.9, etc. Among them, grades 8.8 to 12.9 are called high-strength and
high-grade hexagon bolts.
