Phosphate Coated Self Tapping Screws Wall Plasterboard Fastening Hardware

Phosphate Coated Self Tapping Screws Wall Plasterboard Fastening Hardware is a dedicated fastener designed exclusively for plasterboard interior decoration projects. The product adopts medium-carbon steel as raw material, with full thread rolling forming technology, thread tooth height tolerance controlled within ±0.03mm, which ensures stable biting force during installation and effectively avoids sliding teeth and loosening problems in long-term use. Ningbo Gangtong Zheli Fasteners Co., Ltd. has set up a special production line for this series of fasteners, with standardized production flow from raw material incoming inspection to finished product packaging.

Surface Treatment & Corrosion Resistance Advantage

The core competitiveness of Phosphate Coated Self Tapping Screws Wall Plasterboard Fastening Hardware lies in its professional phosphating anti-rust process. The manganese phosphate film thickness is stably maintained at 8μm–12μm after treatment, passing the neutral salt spray test for more than 48 hours without red rust, fully adapting to humid indoor construction environments such as kitchens and bathrooms. The trumpet-shaped countersunk head can be completely embedded into the plasterboard surface without protruding, which simplifies subsequent putty leveling and painting construction steps and reduces overall decoration labor costs.

Production Capacity & Global Delivery Support

Ningbo Gangtong Zheli Fasteners Co., Ltd. arranges daily production capacity of Phosphate Coated Self Tapping Screws Wall Plasterboard Fastening Hardware up to 12 million pieces, and maintains conventional specifications in permanent stock. The factory implements ISO9001 quality system inspection, each batch of finished products will conduct sampling tensile force detection; the minimum tensile breaking load of conventional 3.5mm diameter products reaches more than 1100N, meeting the fastener load requirements of mainstream European and American building decoration standards.

Application Scenarios & Stable Cooperation

This series of fasteners covers almost all plasterboard installation scenarios including partition walls, suspended ceilings, wall cladding and light steel keel connection, and has long-term stable cooperative building material distributors in Southeast Asia, the Middle East and Europe. Every batch of delivered Phosphate Coated Self Tapping Screws Wall Plasterboard Fastening Hardware is attached with factory inspection report, so overseas purchasers can complete local customs clearance and quality filing smoothly without additional testing procedures.
