Bugle Head Drywall Screw Twinfast Thread

Twinfast Thread Drywall Screw with Bugle Head, also known as double-lead drywall screw, is a high-efficiency self-tapping fastener specially engineered for gypsum board installation in drylining construction. The twinfast (double-start) thread enables faster driving speed and superior holding performance compared with standard single-thread drywall screws. The classic bugle head prevents tearing of gypsum board paper face during screwing, leaving a smooth, recessed surface ready for joint compound and painting.

Key Features

1. Bugle Head (Phillips #2 Drive) The curved trumpet-shaped bugle head seats gently into drywall without cutting or ripping the paper liner. Phillips cross recess provides stable bit engagement, reducing cam-out and over-driving risk. It achieves a flush finished surface after installation.
2. Twinfast Double Lead Thread Dual parallel threads run along the screw shank. This twinfast geometry delivers two major benefits:

• Faster penetration: advances twice as fast per revolution to raise installation productivity.
• Optimized pull-out resistance: locks firmly into wood studs or light-gauge metal studs, resisting loosening under vibration.

3. Sharp Self-Tapping Point Sharp needle point cuts directly into gypsum board and substrate, no pre-drilled pilot hole required for most drywall applications.
4. Material & Surface Finish Base material: Hardened C1022 carbon steel. Available finishes: Black phosphate, bright zinc plated (BZP), blue white zinc, offering different levels of rust protection for interior drywall projectsnewspider…..
5. Full Size Range Metric sizes: 3.5mm, 3.9mm, 4.2mm, 4.8mm; lengths from 13mm up to 150mm. Inch sizes are also available to meet international construction standards. Collated strip version for auto-feed screw guns is optional.

Applications

• Fastening gypsum drywall / plasterboard to wooden studs
• Drywall fixing to light metal studs
