SPAX Pan Head Screw T-STAR plus Metal Zinc Wood 40 mm Length 4.5 mm Diameter 200 Pack

The SPAX Pan Head Screw T-STAR plus Metal Zinc Wood 40 mm Length 4.5 mm Diameter 200 Pack provides a reliable and precise fastening solution for various woodworking and assembly projects. Manufactured from durable metal with a protective zinc coating, these screws offer dependable resistance against wear and corrosion during regular use. Each screw features a pan head design combined with a T-STAR plus drive system, ensuring secure bit engagement, optimal force transmission, and reduced risk of slip during driving. With a length of 40 mm, a thread length of 3.7 cm, and a thread diameter of 4.5 mm, this fastener is engineered to deliver strong holding power and high head traction force. The inclusion of 4CUT technology allows for efficient driving without the need for pre-drilling in most wood types, while ground serrations enable quick and secure fastening by minimizing wood splitting.

Advantages

These metal zinc wood screws offer multiple functional benefits that enhance efficiency and structural reliability. The specialized pan head design ensures a flush finish and higher head traction force, which contributes to the secure attachment of metal fittings and wooden elements. The T-STAR plus drive effectively eliminates the cam-out effect, allowing for smoother and safer installation. Additionally, the integrated 4CUT point displaces wood fibers to prevent splitting, reducing the necessity of pre-drilling and saving time during large-scale assembly work. The blue zinc plated finish provides a clean appearance while offering baseline surface protection.

Suitable for

• Woodworking and furniture assembly
• Attaching metal fittings to wood
• General construction and carpentry tasks
• Indoor wood-to-wood joinery

When it may not be suitable

This product may not be ideal for outdoor environments exposed to continuous moisture or corrosive elements, as the zinc coating provides limited weather protection compared to stainless steel. It is also unsuitable for non-wooden materials such as concrete, brick, or thick metals without appropriate anchors or pre-drilling.

Key specifications

• Length: 40 mm
• Thread diameter: 4.5 mm
• Thread length: 3.7 cm
• Material: Metal with zinc coating
• Head type: Pan head
• Drive type: T-STAR plus
• Quantity per pack: 200 pieces

How to use

Select the appropriate T-STAR plus driver bit to match the screw head size for optimal power transmission and to prevent bit slippage. Position the screw perpendicular to the wooden surface or through the designated hole of the metal fitting. Drive the screw steadily using a power drill or manual screwdriver. Thanks to the 4CUT point and ground serrations, the screw will cut into the wood fibers efficiently. Drive until the pan head rests flush against the material surface, taking care not to overtighten and damage the surrounding wood structure.

What to consider before purchase

• Verify that the 40 mm length and 4.5 mm diameter match the thickness and load requirements of your specific application
• Confirm that the intended use is primarily with wood materials
• Check that you have a compatible T-STAR plus driver bit for installation
• Evaluate the environmental conditions to ensure standard zinc-coated fasteners provide sufficient corrosion resistance for your project

Usage recommendations

For best results, store the screws in a dry environment to preserve the zinc coating. Always wear appropriate personal protective equipment when operating power tools, and test on a scrap piece of wood if unsure about material density and pre-drilling requirements.
