Slotted Flat Head Cap Screws

Slotted flat head cap screws are used where the top of the screw head is to be flush with one of the assembly surfaces. The underside of the screw head and the accompanying hole are countersunk at an 82-degree (includes angle). Flat socket head cap screws are preferred over slotted flat head cap screws if assembly and disassembly are frequent because the drive is less likely to strip with repetitive use.
