Hefei SENOTECH New Materials Co., Ltd leverages years of experience in fastener supply to bring you premium Gypsum Board Screws for Partition Wall. Engineered with a grey phosphate coating, coarse thread, sharp point, and an innovative no-snapping design, these screws deliver consistent performance in drywall and partition wall installations. As a reliable trading company with an annual export value of US$1-1.5 million, we serve markets across North America, South America, Europe, Asia, Africa, and Oceania, ensuring global standards of quality and reliability.
Each screw is manufactured from high-quality carbon steel and undergoes a precise phosphate treatment that provides excellent corrosion resistance and a uniform grey finish. The coarse thread offers superior holding power in gypsum board and light-gauge metal studs, while the sharp point enables quick penetration without pre-drilling. The no-snapping design minimizes screw breakage during high-speed driving, reducing waste and downtime on your job site.
Whether you are a contractor working on commercial partition walls or a DIY enthusiast installing interior drywall, these screws are built for efficiency and durability. Below we detail their key features, technical specifications, and the benefits they bring to your projects.
Key Features & Benefits
- Grey Phosphate Finish: Provides robust anti-corrosion protection, ideal for interior environments with varying humidity. The matte grey appearance also reduces glare and blends well with board surfaces.
- Coarse Thread Design: Delivers strong grip in gypsum boards, preventing pull-out and ensuring secure fastening even in thinner panels. Ideal for 1/2" to 5/8" drywall.
- Sharp Point (self-drilling tip): Enables fast, effortless penetration into drywall and light metal studs (up to 0.6mm thickness) without the need for pilot holes, saving time and labor.
- No-Snapping Structure: Advanced metallurgy and heat treatment minimize the risk of screw breakage during installation, especially at high torque. This reduces fastener waste and keeps your work moving smoothly.
- Bugle Head & Phillips Drive: The countersunk bugle head sits flush with the board surface for easy taping and finishing. The deep Phillips cross-recess ensures excellent driver bit engagement, reducing cam-out.
- Versatile Application: Perfect for partition walls, ceiling systems, drywall backing, and other gypsum board assemblies. Compatible with manual and electric screwdrivers.

Frequently Asked Questions (FAQ)
-
Q: Are these screws suitable for both wood and metal studs?
A: These screws are primarily designed for gypsum board to light-gauge metal studs (up to 0.6mm or 24 gauge) and wood studs. For thicker metal studs (>0.8mm), we recommend using a self-drilling screw with a drill point (e.g., Type 17-3). However, for typical partition wall installations, our coarse thread screw works excellently on both substrates. -
Q: What does “no snapping design” mean exactly?
A: The “no snapping” feature refers to an optimized head-to-shank transition and controlled heat treatment that greatly reduces the chance of the screw head breaking off under torque. This design ensures a more robust connection and fewer defective fasteners during high-speed automated or manual driving. -
Q: Do these screws come in bulk or retail packaging?
A: Yes, we offer multiple packaging options: retail boxes (100 or 500 pcs), poly bags, and bulk cartons (e.g., 1,000/5,000 pcs per case). Custom labeling with your brand is also available. -
Q: What is the typical hardness and corrosion resistance of these screws?
A: Core hardness is HRC 35-45, and the case hardness reaches HRC 50+. The grey phosphate coating provides moderate corrosion resistance – typically 24+ hours in salt spray test. For outdoor or high-humidity environments, we recommend a galvanized or stainless steel version (available upon request). -
Q: Can the screws be used with an impact driver?
A: Yes, the #2 Phillips recess is compatible with standard impact drivers and screw guns. However, for best results with the no-snapping design, we recommend using a drywall screw gun with depth adjustment and moderate torque settings. -
Q: Are samples available before placing a large order?
A: Absolutely. We provide free samples (you pay shipping) of any size you need. Simply contact our sales team with your requirements, and we’ll send samples within 3-5 business days. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, our MOQ is 50,000 pieces per size, but we can negotiate smaller quantities for trial orders or customized items. Please reach out to discuss your specific needs. -
Q: Do you have any quality certifications?
A: Our manufacturing partners operate under ISO 9001 management systems, and certificates can be provided upon request. We also conduct in-house testing for thread gauge, hardness, and torque to ensure every batch meets our strict standards.
