Hefei SENOTECH New Materials Co., Ltd is a trusted trading company specializing in high-quality fasteners for the construction industry. Since our establishment in 2020, we have built a solid reputation by supplying premium drywall screws at wholesale prices directly from reputable factories. Our zinc-plated drywall screws, available in full sizes from 13mm to 100mm, are rigorously tested and come with a Mill Test Report to guarantee consistent performance. Whether you need bulk orders for large-scale projects or specific lengths for precision work, our factory-direct supply ensures you receive the best value without compromising on quality.
Product Overview
These drywall screws are designed for fast and secure attachment of drywall sheets to wood or metal studs. The zinc plating provides excellent corrosion resistance, making them suitable for both interior and protected exterior applications. The self-tapping coarse threads ensure quick penetration and a strong hold, while the bugle head design allows for easy countersinking without tearing the paper surface. Our screws meet industry standards for hardness and dimensional accuracy, and each batch is accompanied by a Mill Test Report for traceability.
Key Features & Benefits
- Full Size Range: From 13mm to 100mm – covers all common drywall thicknesses (e.g., 12.5mm, 15mm) and stud types.
- Zinc Plated Finish: Offers reliable corrosion protection, extending the life of the fastener in humid environments.
- Bugle Head Design: Reduces the risk of paper tearing and ensures a flush finish for smooth sanding.
- Coarse Threads: Provide superior grip in wood studs and reduce installation time.
- Phillips Drive: Compatible with standard power tools, reducing cam-out and increasing productivity.
- Mill Test Report Included: Each shipment comes with a test report confirming hardness, tensile strength, and coating thickness – ideal for quality-conscious buyers.
- Factory Direct Pricing: Eliminates middlemen, allowing you to stock high-quality screws at very competitive wholesale prices.
