Blackspur 70mm Chipboard Screws – Structural Fasteners for Professional Timber Work

The Blackspur 125g 70mm Chipboard Screws are the professional choice for projects requiring deep-reach fastening and high pull-out resistance. At 70mm in length, these screws are perfect for structural DIY, such as securing floorboards, building garden furniture, or internal stud-wall construction. At ECO Heat Shop, we provide the robust hardware and fixings necessary to ensure your large-scale timber projects are built to last.

Specifically developed to overcome the challenges of man-made boards, these screws feature a sharp, single-lead thread that cuts cleanly into chipboard and MDF without compromising the material’s integrity. The result is a rock-solid connection that resists loosening, even under the stress of weight or environmental vibration.

Key Features & Benefits

• Countersunk Pozi Head: The PZ recess allows for maximum power transfer from your driver bit, while the flat head ensures the screw sits perfectly flush with the timber surface.
• Anti-Corrosive Coating: The yellow zinc passivation provides a high level of protection against oxidation, making these screws suitable for use in high-moisture areas like kitchens or outbuildings.
• High-Tensile Steel: Forged to withstand significant torque, reducing the risk of the screw head shearing off when driven into dense hardwoods or thick softwoods.
• Reduced Splitting: The thin-body design and deep threads minimize internal pressure within the wood, allowing you to drive the screw closer to the edge of the board safely.
• Versatile Use: A must-have for builders, carpenters, and DIY enthusiasts working on decking, roofing, and heavy furniture repair.
