Description

■ Head shape: Button cap
Rounded head with hex hole is lower and wider than regular cap bolts. In addition, the button cap may have a slightly different head height (JIS, SS), so please check the diagram/standard chart.
Hex wrench is used for tightening, so you can apply strong torque to tighten.

■ Thread Shape: Unifi Fine (UNF) [Full Thread]
Uni-fi is a standard that originates in the USA. Currently it is prescribed by ISO (International Organization for Standardization) to unify standards, Canada, and Britain. "UNF" is finer than the standard pitch of the Unifi standard.
In addition, the "full screw" is the shape of all the threads from the tip of the head to the head seat.

■Material: Iron (SCM435)
It is called chrommolybdenum steel alloy for mechanical structures, and is an alloy steel with good hardening properties.
Contains Cr (chromium) for better corrosion resistance than "iron".
Stronger than "iron" or "S45C".

■Surface treatment: Iron oxide coating
"Black Dye" is a chemical treatment that forms an iron tetrioxide coating. The rust resistance is as "better than fabric" and does not rust easily.
Color is "Black".

Full and half threads may fluctuate
Uni-fi standard (UNC/UNF) and wit bolts are imported, so even with the same size, there is a possibility of "full screw" and "half screw" fluctuations between purchases.
If the "full screw" and "half screws" are different, we will contact you in advance. Thank you for your understanding.
