boltHexagonal cylindrical head bolts have 4.8, 8.8, 10.9, 12.9
levels. Also called hex screws, also called hex bolts. Its head is
hexagonal head, but also cylindrical head. There are stainless
steel and iron by material. Stainless steel has stainless steel
SUS202 hex cylindrical head screws, this is stainless steel
ordinary material, there are stainless steel SUS304 hex cylindrical
head screws, there are stainless steel SUS316 hex cylindrical head
screws.According to the strength of the hex cylindrical head screw,
there are 4.8 hex cylindrical head screws, 8.8 hex cylindrical head
screws, 10.9 hex cylindrical head screws, and 12.9 hex cylindrical
head screws. 8.8-12.9 class hex cylindrical head screws are called
high-strength and high-grade hex bolts.Technological process1.
Drill holes according to the diameter of the other side of the
hexagonal to the requirements.2, use the cold header to forge out
the hex.3, a single piece can be hexagonal punch, with a hammer
out.useSimilar to countersunk head screws, the nail head is
embedded in the machine, the connection strength is larger, but the
screw must be installed and removed with the corresponding
specification hex wrench. Generally used on various machine tools
and their accessories. Products nameBOLTS, NUTS,
