Conventional self-drilling screws leave bare metal heads after installation, which ruin the overall visual effect of color steel roofs and metal curtain walls. Long-term exposure to sunlight and rain will also cause rusting and compromise the sealing of panels. The newly launched painted head self-drilling screws adopt a dual protection structure: galvanized substrate plus electrostatic high-temperature baking paint on the head. The base material goes through precision forming and heat treatment, retaining the core advantage of self-drilling and self-tapping. Pre-drilling is not required; the screw can directly penetrate thin steel plates and complete drilling, tapping and tightening in one operation, greatly shortening on-site construction time.
The screw head paint is applied by electrostatic spraying and cured at high temperature. The coating features uniform thickness and strong adhesion, with excellent UV resistance and weather resistance. Custom color matching is available to match the color of roof and wall panels, achieving a seamless visual integration between fasteners and building facades. Equipped with EPDM waterproof washers, the screws form a tight seal after tightening to block rainwater penetration and reduce roof leakage risks, making them ideal for long-term outdoor applications.
Hengcheng painted head self-drilling screws can be supplied in carbon steel or 410 stainless steel materials, covering popular head types such as hex washer head. A full range of specifications complies with GB/T 15856.4 and relevant standards to support domestic projects and export orders. All products undergo sampling tests for salt spray, torque and drilling performance under the ISO 9001 quality management system to guarantee stable batch quality. Typical applications include color steel factory roof enclosures, sunroom frames, outdoor billboards, metal wall cladding and prefabricated light steel structures.
