Ulti-Mate Stick-Fit Woodscrews - 5.0 x 90mm - 350pk - Yellow

These screws are suitable for fixing hardwood, softwood, man-made timber boards (like MDF, plywood, chipboard, OSB), and sheet metal.

The patented Stick-Fit drive system allows for smooth, stable driving and enables one-handed installation, making it easier to work in awkward positions or when you only have one hand free.

The yellow zinc plated finish provides corrosion resistance, making them suitable for many professional woodworking and construction applications. For highly corrosive environments or prolonged direct exposure to weather, consider specialized coatings.

Yes, the drive system is 100% compatible with both POZI and standard Phillips driver bits. However, using the included Stick-Fit driver bits optimizes the one-handed installation feature.

The Type-17 slash point is a specific cutting tip design that allows the screw to penetrate hard timber more easily and efficiently, reducing the chance of splitting the wood.

Each Trade Tub contains 350 screws.

The Type-17 point is designed to drive through the hardest timber without pre-drilling. However, for extremely dense hardwoods or to prevent splitting in sensitive materials, pre-drilling a pilot hole may still be beneficial.

Ensure you are using a compatible POZI or Phillips driver bit. Check if the Stick-Fit driver bit is worn. Reduce driving speed and torque, and ensure the screw is entering the material straight.

Verify that the head is making full contact with the material surface. Ensure the timber is not excessively hard for the screw's countersinking capability, or consider a slightly slower driving speed.

Confirm the Type-17 slash point is clear of debris. Ensure your drill has sufficient power. The wax lubricant aids insertion; if resistance is still high, consider a pilot hole, especially in extremely dense hardwoods.

Ensure the Stick-Fit driver bit is fully seated in the screw head. Use moderate pressure and a consistent driving angle. If using a standard POZI/Phillips bit, ensure it is the correct size and in good condition.
