Wood screw SPAX WKRĘT DO DREWNA A2 TX 4.0×50 mm, stainless A2, pack 200

SPAX WKRĘT DO DREWNA A2 TX 4.0×50 mm, stainless A2, pack 200 is a stainless steel wood screw with a Torx (TX) drive, 4.0 mm shank diameter and 50 mm length. Made from A2 stainless steel, the fastener offers corrosion resistance suitable for use in environments where moisture or occasional exposure to the elements is expected. Delivered as a pack of 200 pieces, it is designed for mechanical joining of timber components, providing reliable hold and reduced risk of thread stripping thanks to the TX drive.

Advantages

The A2 stainless steel construction provides corrosion resistance for outdoor and moisture-prone applications, while the Torx (TX) drive reduces cam-out and allows higher torque transfer compared with slotted or Phillips heads. The 4.0×50 mm dimensions balance penetration depth and holding power in a wide range of soft and hardwoods. Supplied in a bulk pack of 200, the set is convenient for larger projects and reduces the need for frequent reordering.

Suitable for

• Exterior woodwork such as cladding and fascias
• Decking and garden structures exposed to rain and humidity
• Timber joinery, frames and furniture requiring stainless fasteners
• Applications where reduced corrosion and long-term durability are required

Key specifications

• Material: A2 stainless steel (corrosion resistant)
• Drive type: Torx (TX) for improved torque transmission
• Diameter: 4.0 mm
• Length: 50 mm
• Pack quantity: 200 pieces
• Intended use: fastening wood to wood and general timber assembly

How to use

Select an appropriate pilot hole size based on the wood species and density to avoid splitting; for most softwoods a reduced or no pilot hole may be acceptable, while hardwoods typically require a pilot hole. Use a TX-compatible driver bit and a cordless drill or screwdriver with controlled torque. Drive the screw square to the surface until the head is flush or slightly countersunk, taking care not to over-torque which can damage the head or strip the drive. For exposed outdoor installations, ensure mating surfaces and surrounding components are also corrosion resistant to maximize service life.

Usage recommendations

When installing in hardwood or near board ends, pre-drill to the recommended diameter and consider using a countersink for a clean finish. Clean and dry timber surfaces before fastening and avoid contact with incompatible metals to reduce risk of galvanic corrosion. Store the screws in a dry place and use appropriate personal protective equipment when working with power tools.
