Stock Up Your Workshop with the Ultimate 500-Piece Screw Pack

Stop running to the hardware store mid-project. Our 500-Piece Assorted Black Screw Mix is designed for the serious DIYer and trade professional who wants to get the job done efficiently. We've packed the three most critical sizes for stud wall construction and general joinery into one heavy-duty value bundle.

What's Inside the Box?

1. 200 x Precision Fixers (3.5mm x 25mm): The perfect length for attaching 12.5mm plasterboard to timber studs, fixing thin backboards to cabinets, or joining 18mm sheets. Small but mighty.

2. 200 x The "Go-To" Size (3.5mm x 35mm): The industry standard for drywall and general wood-to-wood fixing. Long enough to grip securely, short enough not to protrude dangerously.

3. 100 x The Beast (4.8mm x 100mm): These are the heavy hitters. At 100mm (4 inches) long and 4.8mm thick, they are designed for structural framing. Perfect for joining two pieces of 4x2 (47mm) CLS timber together. Most mixed packs leave these out - we include 100 of them!

Why Choose Black Phosphate?

• Speed: The ultra-sharp needle point bites instantly - often eliminating the need for pilot holes in softwoods.

• Grip: Coarse thread design prevents stripping in crumbly materials like plasterboard or chipboard.

• Finish: The matt black finish is discreet in furniture assembly and creates a porous surface that joint filler sticks to perfectly.

Technical Specifications:

• Drive Type: Phillips / Pozi Compatible (PH2/PZ2).

• Head Style: Bugle (Countersunk).

• Material: Hardened Steel.

• Finish: Black Phosphate (Dry).

• Thread: Coarse (Single Thread).

Ideal For:

• Building Stud Walls: Framing with the 100mm, boarding with the 35mm.

• Shop Fitting: Rapid assembly of displays and shelving.

Package Contents:

• 200 x 3.5mm x 25mm Screws

• 200 x 3.5mm x 35mm Screws

• 100 x 4.8mm x 100mm Screws

• THE ULTIMATE 500-PIECE PROJECT PACK: A carefully curated selection of the most used sizes for stud walling and joinery. Contains 200x Short (25mm), 200x Standard (35mm), and 100x Extra Long (100mm) Heavy Duty Screws.

• FRAMING & FINISHING SORTED: Use the massive 100mm (4 inch) screws for structural framing (joining 4x2 timber) and the 25mm/35mm screws for fixing plasterboard, plywood, or cladding to the frame. No need to buy separate boxes.

• RAZOR SHARP "BUGLE" HEAD: Features a Bugle Head design that sinks flush into drywall and softwoods without tearing the paper surface or crushing the timber fibres, ensuring a neat, professional finish every time.

• RAPID DRIVE COARSE THREAD: The deep, coarse thread geometry drives into timber and masonry plugs faster than standard screws, providing exceptional pull-out resistance and grip in stud work, chipboard, and MDF.

• BLACK PHOSPHATE COATING: Not just for looks - the chemical black phosphate coating offers mild corrosion resistance (superior to plain black oxide) and holds paint/filler better than zinc screws, making them invisible once decorated.
