KYA 3.5×42mm Collated Drywall Screws are designed for repetitive ceiling drywall and construction fastening with compatible auto-feed screw guns. The screws are manufactured from C1022A steel and feature a bugle head for controlled seating into drywall and board surfaces.
The featured screw measures 3.5mm in diameter and 42mm in length. Available surface treatments include black phosphating, grey phosphating, yellow zinc and blue-white zinc. The 3.5×42mm size is packed at 1,000 screws per box, 10,000 screws per carton and 240,000 screws per pallet.
KYA references compatible collated screw systems from Makita, Hilti, SENCO, Festool, Hitachi, Ridgid and Bosch. Because screw magazines and auto-feed systems differ in screw length range, strip geometry, drive, thread and point requirements, confirm the exact tool model before ordering.

Thread type, point type, drive recess and exact strip configuration should be confirmed according to the substrate and auto-feed screw gun being used. These parameters determine whether the screw is suitable for wood framing, light-gauge steel or another application.
Collated screws are arranged sequentially on a carrier strip so a compatible auto-feed screw gun can advance the next fastener automatically. This reduces the need to handle and load individual loose screws during repetitive ceiling and drywall installation.
For overhead work, consistent auto-feeding can help installers maintain a steady fastening sequence while keeping one hand available to control the tool or workpiece. Actual installation speed depends on the screw gun, magazine, operator and jobsite conditions.
The featured screw is 42mm long with a 3.5mm nominal diameter. Screw length should be selected according to board thickness, number of board layers, substrate and the required fastener penetration.
For ceiling drywall attached to timber or metal framing, confirm that the 42mm length and the selected thread and point configuration meet the board manufacturer's installation requirements and applicable project specification.
The bugle head has a curved transition between the shank and head. This profile is commonly used for drywall because it allows the screw head to seat progressively into the board surface.
Correct depth adjustment remains important. The screw should be set sufficiently for finishing without being driven so deeply that the drywall face paper is excessively damaged.
The 3.5×42mm collated screws are manufactured from C1022A steel. The appropriate screw geometry must still be selected according to the material being fastened.
Drywall-to-wood, drywall-to-light-gauge steel and heavier metal framing can require different thread and point configurations. Specify the framing material and thickness when requesting a quotation if the required screw configuration is not already known.
| Surface Treatment | Selection Guidance |
|---|---|
| Black Phosphating | Common option for suitable dry interior drywall applications. |
| Grey Phosphating | Alternative phosphate finish for compatible interior fastening requirements. |
| Yellow Zinc | Zinc-plated surface option where a plated screw is required. |
| Blue-White Zinc | Zinc-plated option for compatible general fastening applications. |
For exterior, continuously damp, chemically exposed or other corrosion-sensitive locations, confirm the required coating and corrosion-resistance specification before ordering. Standard phosphate or zinc finishes should not automatically be treated as suitable for every exterior environment.
KYA references Makita, Hilti, SENCO, Festool, Hitachi, Ridgid and Bosch among the compatible tool brands for its collated screw range.
Compatibility should be checked by exact tool or magazine model. Different systems may use different carrier strips, screw spacing, screw-length ranges, drive recesses and nosepiece configurations.

The 3.5×42mm size is intended for repetitive fastening with compatible auto-feed screw systems. Application suitability depends on the selected thread, point, coating, board type and framing substrate.
Ceiling drywall panel installation
Gypsum board installation
Drywall to compatible timber framing
Drywall to compatible metal framing when the correct screw configuration is selected
Interior partition and lining systems
Furniture and cabinet assembly where the screw specification is suitable
Compatible board fastening where permitted by the board manufacturer
For cement board, fiber-cement board, decking or other demanding applications, confirm that the screw material, thread, point, head and coating meet the board manufacturer's and project requirements before use.
For a replacement or bulk order, specify more than diameter and length. Auto-feed screw systems also depend on screw geometry and carrier-strip compatibility.
