GB-T 70.3 Hexagon Socket Countersunk Head Screws

 GB-T 70.3 Hexagon Socket Countersunk Head Screws with Reduced Loadability, also known as hexagon socket head flange screws, are a type of fastener with specific design and function. GB-T 70.3 Hexagon Socket Countersunk Head Screws with Reduced Loadability has a round outer edge and a recessed hexagon in the middle. It has six contact surfaces with the wrench, which allows it to fully disperse when it is stressed, thereby reducing Risk of damage and slippage. Due to the head design, head size and hexagonal penetration depth of GB-T 70.3 Hexagon Socket Countersunk Head Screws with Reduced Loadability, its load-bearing capacity is relatively low, but this also provides advantages in some specific applications.
