KYA 3.5×55mm collated drywall screws are C1022A steel fasteners with a bugle head, supplied in plastic collated strips for compatible auto-feed screw systems. The 55mm length provides additional available penetration compared with shorter screws in the same collated drywall screw family.
KYA lists black phosphated, grey phosphated, yellow zinc and blue-white zinc surface treatments for this range. The 3.5×55mm version is packed at 1,000 screws per box and 10,000 screws per carton.
The exact framing material and tool compatibility depend on more than screw length. Buyers should confirm the required thread, point, drive recess, plastic-strip dimensions and auto-feed tool model before ordering for drywall-to-wood, drywall-to-metal or other fastening applications.

Collated screws are mounted sequentially on a plastic carrier strip so a compatible auto-feed screwdriver can advance the next screw after each fastening cycle. This format is useful for repetitive drywall installation because the installer does not need to load individual loose screws after every drive.
The 55mm length provides more available penetration than 25mm, 30mm, 35mm, 38mm, 42mm, 45mm or 50mm screws in the same KYA size range. The correct length depends on board thickness, number of layers, framing material and required thread engagement.
The KYA product is specified at a nominal 3.5mm diameter. Screw diameter should be considered together with thread form and receiving material rather than used by itself to determine suitability.
KYA specifies C1022A steel for this collated drywall screw family. The exact screw configuration should still be selected according to the framing substrate, point style, thread form and required surface treatment.
The bugle head profile is commonly used in gypsum-board fastening because its curved transition allows the screw head to seat into the board face. Screw-gun depth should be adjusted so the head is correctly seated without excessive damage to the face paper.
The plastic carrier strip allows multiple screws to be loaded into an auto-feed system. Screw spacing, strip geometry, drive recess and screw dimensions must correspond to the exact tool or magazine.
KYA lists black phosphated, grey phosphated, yellow zinc and blue-white zinc finishes. Finish selection should be based on the intended installation environment and project requirements.
A 55mm drywall screw provides additional length for installations where the fastener must pass through a thicker board assembly before achieving the required engagement in the framing material.
The longest available screw should not be selected automatically. Excess screw length can be unnecessary, while insufficient length can reduce available thread engagement after the screw passes through the board.
| Selection Factor | Why It Matters |
|---|---|
| Board Thickness | Part of the 55mm screw length is consumed passing through the gypsum board before reaching the framing. |
| Single or Multiple Layers | Multiple board layers generally require a longer fastener than a single board layer. |
| Framing Material | Wood and metal framing require different thread and point configurations. |
| Required Thread Engagement | Enough threaded length must remain in the receiving substrate after passing through the board. |
| Auto-Feed Tool Range | The screw gun or magazine must accept a 55mm collated fastener. |
The 3.5×55mm dimensions do not by themselves determine whether a screw is intended for wood framing or steel framing. Thread pitch and point style are critical selection factors.
| Application | Fastener Characteristics to Confirm |
|---|---|
| Drywall to Wood Framing | Appropriate wood thread, point type, 55mm length and required thread penetration. |
| Drywall to Light-Gauge Steel | Suitable fine-thread or specified metal-framing screw geometry and allowable steel thickness. |
| Drywall to Heavier Steel | Self-drilling point and drilling capacity appropriate for the steel thickness. |
Hilti, Makita and other professional systems sell different collated screw configurations for different substrates even when the overall screw length is similar. Confirm the KYA thread and point configuration before specifying the screw for a particular framing material.
A 55mm collated screw sits near the upper end of the operating range of many drywall auto-feed screwdrivers. The tool must accept both the screw dimensions and the specific plastic-strip format.
For example, the Makita DFR551 is specified for collated drywall screws approximately 3.5–4.2mm in diameter and 25–55mm in length. A KYA 3.5×55mm screw therefore falls within that published dimensional window, but final compatibility still depends on the carrier strip, drive recess and screw configuration.
| Featured Screw Size | 3.5 × 55mm |
| Reference Auto-Feed Range | Tool must accept 55mm collated screws |
| Example Tool | Makita DFR551 accepts 3.5–4.2mm diameter × 25–55mm collated screws |
| Other Tool Families | Compatibility depends on exact magazine, screw strip and fastener specification |
| Before Ordering | Confirm tool manufacturer, exact model, drive recess, screw strip dimensions and framing substrate |
Do not assume compatibility with every Makita, Hilti, SENCO, Festool, Hitachi, Ridgid or Bosch auto-feed screwdriver simply because the tool uses collated screws. Each model has a defined screw-length and carrier-strip range.
Black phosphate is a common finish for carbon-steel drywall screws used in clean, dry interior construction. It should not automatically be treated as an exterior corrosion-resistant coating.
Grey phosphate is also listed within the KYA collated drywall screw range and is intended for applications where that finish is specified.
KYA lists yellow zinc and blue-white zinc as additional finish options. The required coating should be selected according to the installation environment and purchasing specification.
Surface treatment alone does not make a drywall screw suitable for decking, structural framing or cement board. Those applications require the complete fastener specification to be checked.

The product has a nominal diameter of 3.5mm and a nominal length of 55mm, approximately 2-3/16" long.
KYA specifies C1022A steel for this collated drywall screw range.
The screws use a bugle head, a common head profile for gypsum-board fastening.
A 55mm screw provides additional available penetration for thicker board assemblies or applications requiring more threaded engagement. The correct length still depends on board thickness and framing material.
Yes, when the selected 55mm screw has the appropriate thread and point for wood framing. Hilti and Makita both offer 55mm collated drywall-to-wood screws, but the KYA thread configuration should be confirmed before ordering for this application.
Not automatically. Metal framing can require a different thread and point from wood framing. Confirm the steel thickness and required screw configuration first.
Makita specifies the DFR551 for collated screws from approximately 3.5–4.2mm in diameter and 25–55mm in length. The KYA 3.5×55mm dimensions therefore fall within that published size range, but the plastic strip, drive recess and thread configuration must also match.
No. Individual tools and magazines have specific screw-length, strip, drive and feed requirements. Provide the exact tool model when checking compatibility.
Do not use standard drywall screws as generic decking screws. Makita, for example, lists a separate 55mm stainless decking screw with a different diameter and thread configuration. Decking requires a fastener selected for the deck material, load and exposure environment.
Only if the board manufacturer permits the exact fastener configuration. Cement-board screws often use different head geometry, threads, points and corrosion protection from standard drywall screws.
KYA lists black phosphated, grey phosphated, yellow zinc and blue-white zinc finish options within this product range.
The 3.5×55mm configuration is listed at 1,000 screws per box and 10,000 screws per carton.
Check the screw diameter, 55mm length, thread type, point, drive recess, head design, plastic-strip width, screw spacing and exact auto-feed tool or magazine model.
Provide the required quantity, auto-feed screw gun manufacturer and model, board thickness, framing material, required surface treatment and delivery destination. Specify 3.5×55mm collated drywall screws for the product shown on this page.
The original product listing covers drywall, cement-board and woodworking projects, including furniture, decks and framing, and names Makita, Hilti, Senco, Festool, Hitachi, Ridgid and Bosch screw guns. Screw type and tool compatibility depend on the exact thread, point, drive and strip dimensions; confirm the tool model and substrate requirements before ordering.
