[Features]
· Compared to the JIS standard, the TKS standard features a deeper hex socket, allowing for more stable fastening and improved loosening prevention.
· Since the head has a countersunk shape, the head of the screw does not protrude after fastening, providing excellent safety. Additionally, it requires less space for installation than conventional hex socket head cap screws.

TKS Standard (Tokosha Metal Works Standard)

· Since the head has a hex socket, tightening can be done securely even in places where it is difficult to use a screwdriver.
· Because it can be tightened with a hex wrench, it is often used for large equipment or areas where secure fastening is required, providing excellent safety.
In addition, it requires less space for work compared to conventional hex socket head cap screws.
