Product Information

Full details

This professional-grade, 780-piece screw assortment is designed for DIY enthusiasts and trade professionals needing a versatile collection of fixings for chipboard and wood projects. The primary benefit is the comprehensive range of sizes combined with a durable, corrosion-resistant yellow zinc finish that ensures long-term reliability. A notable caveat is that while the kit covers a broad spectrum of general carpentry, it is strictly intended for wood and chipboard applications and should not be used in masonry or metal without appropriate pilot holes and specialized hardware.

FAQs

Can these screws be used outdoors?

Yes, the yellow zinc passivated finish offers enhanced rust resistance, making them suitable for many outdoor wood projects.

Do I need special tools to drive these?

No, they use a standard Pozi drive, which works with any common screwdriver or drill bit marked with a 'PZ' designation.

Are these screws self-tapping?

While they are sharp, they are designed for chipboard and wood. It is always recommended to drill a pilot hole for the best finish and to prevent wood splitting.

What is the largest size in this kit?

The largest screws in the set are 5mm in diameter by 80mm in length.

Is the storage case included?

Yes, the product comes in a convenient, resealable blow-molded case with clearly labeled compartments.

Troubleshooting

Screw head strips during installation

Ensure you are using the correct size Pozi drive bit and apply consistent, firm downward pressure while driving.

Wood splits when driving a screw

You are likely bypassing the need for a pilot hole; drill a small guide hole into the material before inserting the screw.

Screw is difficult to drive in fully

Verify that the pilot hole is deep enough and that you are not encountering a dense knot or hidden obstruction in the wood.

Setup, Compatibility & Care

  • Compatibility: These screws are fully compatible with standard manual screwdrivers and electric impact drivers equipped with Pozi-drive bits.
