Our this bolts are made by CNC machine,so they are very high precision.the tolerance -0.008 to -0.029.
Besides of this precision bolt,We can also make standard bolt , non-standard bolt according to your requirement according to your drawing,and offer flat washer,spring washer,nut.
Bolt and screw are mechanical fasteners used to position and hold two or more components together.But they have unique applications and characteristics.Bolts are used with nuts,whereas screws make threads of their own or are used on the threaded component.But in some scenarios bolts can work as screws if used on the threaded component.In actual practice,there is no defined difference between bolt and screws.
A Bolt is an externally threaded fastener used along with internally threaded components such as nuts to position and holds two or more parts.Bolts are used along with washers and nuts for high-duty applications.
hexagonal head bolts with shank, also called semi-threaded hexagonal bolts  or half threaded hexagonal bolts, according to the thread length. DIN 931 hexagon bolts are often used in conjunction with hex nuts. the tow parts are connected into a whole by threaded connection, which is a detachable connection. the self-locking performance of the fine thread hexagonal bolt is better, and it is mostly used for parts subject to greater impact, vibration or alternating load, can also be used for fine adjustment mechanism.
OKE can offer variety of bolts to meet your requirement,ordinary,and high-precision bolt.
