Professional Twin Thread Screws For Wood

These versatile twin thread screws are the workhorse fastener for a vast range of interior construction and joinery applications.

Stop wasting time with screws that snap, strip, or require pre-drilling. This twin thread screw is the go-to fixing for efficient, high-quality results in softwood, chipboard, MDF, and for fixing into masonry with a plastic plug.

The core of this screw's performance is its twin-thread design, which drives up to twice as fast as a conventional single-thread screw. This double-helix geometry means less time driving and less fatigue, boosting your productivity on high-volume jobs. For longer screws, a partially threaded shank ensures a powerful clamping action, pulling timbers together for a tight, secure joint without the "jacking" effect common with fully threaded screws.   

Designed for modern power drivers, the screw features a robust Pozi drive recess for superior bit engagement and dramatically reduced cam-out, allowing for confident, one-handed driving. The double countersunk head is reinforced to prevent shearing under high torque and creates its own clean, flush finish in the material.   

Manufactured from case-hardened carbon steel, this screw combines a hard, wear-resistant surface with a tough, ductile core, providing the perfect balance of driving performance and strength to prevent snapping under load. A sharp 25° point ensures a rapid start, biting instantly into the material and often eliminating the need for a pilot hole. 

• Application: Ideal for softwood, chipboard, MDF, and masonry with plugs.
• Thread Type: 60° Twin-Thread for rapid installation.  
• Shank Type: Parallel shank, partially threaded on longer sizes for a strong clamping action.  
• Head Type: Double Countersunk for a flush finish and reduced head shear.  
• Drive Type: Pozi (PZ) recess for superior bit engagement and reduced cam-out.
