Truss/Wafer Head Phillips Head Self Drilling Screw: Supports ODM and OEM.
1.Large bearing surface to avoid crushing or denting thin sheets
The head diameter is much larger than that of pan head screws of the same size, functioning like an integrated flat washer. When fastening color steel sheets, thin aluminum panels, light steel sheets and thin iron sheets, pressure is evenly distributed to avoid dimpling, tearing or warping of the substrate.
2.Phillips drive for fast installation with electric screwdrivers Low-profile head to reduce interference and scratching The head height is much lower than a pan head. It sits flush against the profile surface. When installed under insulation, overlapping panels or edge trims, it will not puncture surface layers or scratch waterproof membranes.
3.Cost-effective
For the same material and size, wafer head screws are cheaper than hex flange self-drilling screws, ideal for high-volume non-load-bearing enclosure applications.
4.In addition to the wafer head self tapping screw, self-tapping screws are also available with pan heads, countersunk heads, and hex flange heads, and are compatible with modular cabinets.
Häufig gestellte Fragen: Q:Can this screw drill thick steel directly? A:Standard type works for steel sheet up to 2.5mm. Choose heavy-duty longer self-drilling screws for thicker metal. Q:Are different lengths and diameters available? A:Yes, abundant standard sizes in stock, non-standard sizes can be customized.
