HighStrength Chipboard Screws Factory Leading China Suppliers of Wood Fasteners

Our Color Zinc Coated Coarse Thread Drywall Screws are engineered specifically for the efficient and reliable installation of gypsum wallboard (drywall) to wood or light-gauge steel studs. Featuring a sharp self-drilling point, aggressive coarse threads, and a durable color zinc coating, these screws are designed to drive quickly, seat flush without tearing the paper face, and hold firmly for a long-lasting finish. The distinctive color coating not only provides excellent corrosion resistance but also allows for easy visual identification during and after installation. This is the essential fastener trusted by professional drywall contractors and DIY enthusiasts for creating smooth, stable walls and ceilings.

Our DIN 7991 Hexagon Socket Countersunk Head Screws (also known as flat head socket cap screws) are precision-engineered fasteners designed to sit completely flush with or below the workpiece surface. Featuring a flat 90° countersunk head and an internal hexagon socket drive, these screws provide a smooth, snag-free finish while delivering high clamping force through efficient torque transmission .

Manufactured in strict compliance with DIN 7991 (equivalent to ISO 10642) standards, these screws are ideal for applications requiring aesthetic appearance, space clearance, or safety from protruding heads

Our Flange Sleeve Anchor (also known as flange nut sleeve anchor) is a high-performance expansion anchor designed for permanent fastening into concrete, solid brick, and masonry. Featuring an integrated hex flange nut, this anchor provides superior load distribution and a finished appearance in one complete assembly

Our Square Head Bolts (also known as square neck bolts or coach bolts) feature a distinctive four-sided square head and a square shoulder beneath the head. This classic design provides a positive locking action when the square shoulder engages with the mating material, preventing rotation during installation. Ideal for wood-to-metal fastening, machinery assembly, and traditional industrial applications.

Our Wedge Anchors represent the industry standard for high-strength, permanent fastening in solid concrete. Designed for critical structural and seismic applications, these anchors provide unparalleled shear and tensile strength by creating a powerful mechanical lock within the base material. Engineered for reliability and performance, they are the preferred choice for construction professionals, engineers, and contractors who demand absolute confidence in their fastening systems.

Our UNI 5587 Thick Hex Nuts, often referred to as "Heavy Hex Nuts" or "Extra Thick Nuts," are engineered to deliver exceptional load-bearing capacity and secure performance in the most demanding applications. Manufactured to the exacting dimensional and mechanical specifications of the UNI 5587 Italian national standard, these nuts feature a significantly greater height and width across flats than standard hex nuts. This robust design provides a larger bearing surface, deeper thread engagement, and superior resistance to vibration loosening, making them the ideal choice for structural, heavy machinery, and critical assembly environments where safety and reliability are paramount.

Our DIN 975 Threaded Rods (also known as Fully Threaded Studs, All-Thread Rods, or Threaded Bars) are precision-manufactured, continuous thread fasteners designed for maximum versatility in industrial, construction, and mechanical applications. As defined by the German DIN 975 standard, these rods feature uninterrupted threads along their entire length, providing infinite adjustability and the ability to be cut to any required size on-site . Manufactured from high-quality materials including carbon steel and stainless steel, our threaded rods serve as the essential connecting element in countless assemblies—from suspended ceiling systems and pipe hangers to heavy machinery anchoring and structural steel connections. The combination of standardized dimensions, material options, and full-thread design makes DIN 975 threaded rods the ultimate "cut-to-length" fastening solution for professionals worldwide.

Our Drywall Screws are precision-engineered fasteners specifically designed for attaching gypsum plasterboard (drywall) to wood studs or light-gauge steel framing. Featuring a sharp self-drilling point, bugle head, and deep threads, these screws drive quickly, seat flush without tearing the paper face, and provide exceptional holding power for a smooth, professional finish.
