Carbon Steel Collated Screws
Product Overview
This 6-18×25-45 color zinc collated drywall screw is a dedicated fastener for use with collated automatic screw guns, featuring a USA standard 6# screw shank with 18 threads per inch fine-thread design, covering multiple length options from 25mm to 45mm; the surface is available in two passivation coatings: yellow color zinc and iridescent color zinc, combined with a Phillips bugle countersunk head and a sharp pointed tip, arranged in rows on a white plastic collated strip. Specifically designed for batch construction of gypsum board partition walls and suspended ceilings, it accommodates both light steel keel and wood substrate fixing requirements. Compared to traditional bulk drywall screws, it significantly improves construction efficiency and is a mainstream automated fastening accessory for residential and commercial batch-refined decoration projects.
Product Applications
Commercial refined decoration projects: Batch installation of light steel keel, gypsum board partition walls, and suspended ceilings in shopping malls, office buildings, and hotels, greatly shortening construction timelines and suitable for large-area standardized decoration work;
Residential indoor suspended ceilings and partition walls: Fixing of gypsum board suspended ceilings and lightweight partition walls in living rooms and bedrooms, suitable for light steel keel and thin wood keel substrates;
Fixing of light decorative panels: Fastening of fiber cement boards, thin decorative panels, gypsum shaped boards, and other lightweight panel materials;
Applicable environment: For dry indoor spaces; not recommended for long-term humid kitchens, bathrooms, outdoor scenarios, or light steel keels thicker than 0.8mm; for humid areas, stainless steel versions should be used, and for thick metal substrates, self-drilling collated screws should be selected.
Product Features
18 fine threads: Bites into light steel without tearing, providing secure grip and preventing panel loosening and bulging;
Color zinc coating: Offers better rust resistance than ordinary black phosphate screws, preventing later yellow rust spots from appearing on walls;
Sharp pointed tip: Eliminates pre-drilling, easily penetrating gypsum boards, thin light steel, and wood substrates;
Phillips bugle countersunk head: Compatible with dedicated screw gun bits, can sink into the panel surface for a flush finish with minimal patching;
Collated strip design: Enables continuous screw feeding with automatic screw guns, providing high construction efficiency and uniform driving depth;
Multiple length options: Full coverage from 25-45mm, suitable for both single-layer and double-layer gypsum board working conditions.
