Truss Head Self Tapping Screws Zinc Plated Carbon Steel with Cross Recessed Drive ST2.2-ST6.3
Truss Head Self Tapping Screws - Cross Recessed Drive, Zinc Plated Carbon Steel (ST2.2-ST6.3)
Our truss head self-tapping screws are engineered for high-volume assembly where a wide, low-profile bearing surface is required. The oversized truss head spreads clamping load evenly over a large bearing area, preventing pull-through in thin sheet metal, while the cross recessed drive ensures positive engagement and consistent torque transfer throughout installation.
Key Features
- Truss Head Design: Extra-wide, low-profile head increases bearing area for thin sheet metal, plastics and composite panels.
- Cross Recessed Drive: Single cross recess accepts standard PH1-PH2 bits for fast, self-centering driving.
- Zinc Plated Carbon Steel: Bright zinc finish provides economical corrosion protection for indoor and sheltered outdoor use.
- ST2.2-ST6.3 Size Range: Full metric self-tapping size coverage from ST2.2 through ST6.3 to match your assembly needs.
- Sharp Type A Point: Self-piercing point starts quickly in pilot holes and cuts its own mating thread.
