Product Description

Factory wholesale 12.9 grade galvanized carbon steel stainless steel SS304 full thread hexagon bolts

Hexagonal 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 process
1. 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.
use
Similar 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.
