How to choose Slotted Flat Head Screws

1. Select different grades of slotted countersunk head screws according to the use environment and stress requirements;

2. Select different diameters and lengths according to the needs of the structure;

3. Choose suitable slotted countersunk head screws according to the torque requirements;

4. Choose products produced by manufacturers with reliable quality and guaranteed brands.

5. When reaming, you need to pay attention to the taper, which should be ninety degrees; if you can not guarantee ninety degrees, then the taper, as far as possible, is less than ninety degrees.
