Round Head U-Drive Screws. U-drive screws (also known as hammer drive screws) are unslotted round head self tapping screws oftenused for attaching nameplates in castings and for sealing drain holes in corrosion proofing tubular structures.
How do you use U drive screws?

The different screw drive types include:
- Slotted.
- Phillips.
- Phillips tamper-resistant.
- Combination.
- Hex external.
- Hex internal.
- Hex tamper-resistant.
- Square recess.
