Product Information

Full details

This guide is for tradesmen and DIY enthusiasts seeking a reliable, high-performance wood screw for diverse material applications. The Ulti-Mate Stick-Fit screws offer a key benefit of stable, one-handed driving with their unique Pozisquare® recess and included driver bit, allowing for easier positioning of materials. A potential caveat is that the slotted shank, while reducing wood splitting, may require careful torque management on very soft woods. These 4.0 x 70mm screws are designed for strength, ease of use, and durability, suitable for hardwood, softwood, engineered timbers, and sheet metal, featuring a corrosion-resistant zinc-plated finish.

Extended Product Information

FAQs

What is the benefit of the Stick-Fit® connection?

The Stick-Fit® connection, combined with the Pozisquare® recess, keeps the screw securely attached to the driver bit. This allows for easier and more stable one-handed driving, freeing up your other hand to position the material being fixed.

Can these screws be used for exterior projects?

The zinc-plated passivated finish offers good corrosion resistance, making them suitable for some exterior applications where mild exposure to moisture is expected. For highly corrosive environments or prolonged direct weather exposure, stainless steel screws may be more appropriate.

What size drill bit should I use for a pilot hole?

The ideal pilot hole size depends on the wood density and screw diameter. For these 4.0mm screws, a pilot hole between 2.5mm and 3.0mm is generally recommended for hardwoods and engineered boards to prevent splitting, while a smaller or no pilot hole might suffice for softwoods.

Are these screws suitable for metal-to-metal applications?

These screws are designed primarily for wood and timber applications, though they can be used for attaching sheet metal to wood. They are not intended for drilling into or fastening metal-to-metal without a suitable substrate like wood.

What does CE approved mean for these screws?

CE approval indicates that the product meets the health, safety, and environmental protection standards required for products sold within the European Economic Area (EEA). It signifies compliance with relevant European regulations.

How do I prevent the screw head from damaging the surface?

The screws feature a self-countersinking head with ribs (on screws 45mm and above) designed to help achieve a flush finish. For very delicate surfaces, consider using a pilot hole and driving the screw carefully until it sits flush, or use a washer if greater surface area bearing is required.

What is the difference between Pozisquare® and a standard Pozidriv recess?

The Pozisquare® recess is Ulti-Mate's enhanced version, designed specifically to work with their Stick-Fit® system, providing superior anti-camout properties and a more secure connection with the driver bit compared to standard Pozidriv.

Troubleshooting

Screw cam-out during driving

Ensure you are using the correct size Pozisquare® driver bit and that it is fully seated in the screw head. Apply firm, consistent pressure.

Wood splitting during insertion

Check if a pilot hole is needed for the specific wood type. Ensure the slotted shank is functioning correctly by not over-torquing the screw. Ease off pressure as the screw fully engages.

Screw not engaging or starting properly

Verify the surface is clear of debris. Ensure the sharp point is making contact and the material is suitable for screw penetration. You may need to re-position or start the hole with a firmer initial pressure.

Driver bit connection feels loose

Confirm the Stick-Fit® connection is clean and free from obstruction. Ensure the driver bit itself is in good condition and not excessively worn.

Pros and Cons

Pros

Enables stable one-handed driving due to the Stick-Fit® system.
Reduces wood splitting with its slotted shank design.
Offers excellent grip and prevents cam-out with the Pozisquare® recess.
Provides strong and reliable fastening across many material types.
Corrosion-resistant finish ensures longevity.
Includes a necessary driver bit in every box.

Cons

Slotted shank might require careful torque management on very soft timbers to prevent over-driving.
Primarily designed for wood and sheet metal; not intended for masonry.
The specific dimensions (4.0 x 70mm) may not suit all project requirements.
While robust, very heavy-duty structural applications might require specialized fasteners.

Setup, Compatibility & Care

Setup: Ensure you are using the correct size Pozisquare® driver bit, which is typically included in the box. Select the appropriate pilot hole size if required for very hard woods or specific applications to ensure optimal performance and prevent splitting.

Compatibility: These screws are highly versatile. They are compatible with:

Hardwood
Softwood
Engineered Timber Boards: Including MDF, plywood, chipboard, and OSB.
Sheet Metal: For attaching metal components to wood or other substrates.

Care: Store screws in a dry environment to maintain the integrity of the zinc-plated passivated finish. Avoid prolonged exposure to excessive moisture or corrosive substances. Clean any debris from the screw heads before driving to ensure the driver bit engages properly. For best results, use a power drill with variable speed and torque settings, especially when driving into softer materials.
