Auveco Hex Head SEMS Tapping Screw Phosphate

Auveco Hex Head SEMS Tapping Screws with a phosphate finish are fastener hardware for automotive, powersports, and general repair. They are also called hex head self-tapping screws or sheet metal screws with captive washers. The hex head lets you drive them with a standard socket or nut driver. The thread-forming design cuts or forms its own mating threads in sheet metal and similar materials.

Key Features:

• SEMS design: The washer is pre-assembled on the screw. This spreads clamping load and cuts down on the number of loose parts to handle during installation.
• Hex head drive: The head gives good tool engagement and torque transfer, and it resists cam-out.
• Tapping thread: The screw forms its own threads as it is driven. This suits panels, brackets, trim, and body and chassis assemblies.
• Phosphate finish: The coating gives light corrosion resistance. It also leaves a dark, uniform surface that suits many OEM-style applications.
• Auveco quality: Auveco has long supplied automotive fasteners and hardware to repair shops and parts counters.
