Wood screw SPAX WKRĘT DO DREWNA A2 TX 3.5×20 mm, stainless A2, 200 pcs

SPAX WKRĘT DO DREWNA A2 TX 3.5×20 mm is a pack of 200 stainless steel wood screws designed for general interior wood fastening. Each screw has a TX (Torx) drive for positive bit engagement and reduced cam‑out, and A2 stainless steel construction to provide moderate corrosion resistance suitable for indoor environments and damp but non‑marine conditions. The 3.5×20 mm dimensions are intended for connecting thin boards, battens, mouldings and light furniture components where a compact fastener is required.

Advantages

The TX drive improves torque transfer and minimizes stripping during installation, making these screws easier to drive with power and manual drivers. A2 stainless steel offers reliable resistance to oxidation and staining in typical indoor and mildly humid settings. The 3.5×20 mm length and 3.5 mm diameter give a balance between holding power and low splitting risk in narrow timber, while the pack of 200 provides a practical quantity for small projects and repeat tasks.

Suitable for

• Assembly of flat‑pack and custom furniture components
• Fixing thin boards, battens, skirtings and mouldings
• Interior carpentry and trim work
• Light structural connections in non‑exterior, non‑marine environments

Key specifications

• Material: A2 stainless steel (moderate corrosion resistance)
• Drive type: TX (Torx) for secure bit engagement
• Dimensions: 3.5 mm diameter × 20 mm length
• Head style: countersunk/flat head suitable for flush finishing
• Quantity: 200 screws per pack

How to use

Choose a TX driver bit matching the screw head size and set the driver to an appropriate torque to avoid over‑driving. For thin or brittle woods, consider pre‑drilling a pilot hole to reduce splitting, using a drill bit slightly smaller than the screw core diameter. Drive screws until the head sits flush with or slightly below the surface depending on the desired finish; countersinking is possible for a cleaner appearance. Use corrosion‑appropriate practices: avoid prolonged exposure to salt water or acidic environments to maintain stainless performance.

Usage recommendations

Store screws in a dry place and handle with appropriate safety equipment. For outdoor or marine applications, select higher‑grade stainless or coated fasteners. When joining hardwoods or heavily loaded connections, use correct pilot holes and check torque settings to ensure joint integrity.
