Double-Thread Decking / Terrace Screw with Torx Drive (Fischer Decking / Terrace Screw)
A specialized dual-thread stainless steel or coated wood screw featuring a small countersunk head and upper fixing thread, engineered specifically for installing wood and composite decking boards.
-
Dual-Thread Design: Lower thread anchors firmly into the timber substructure, while the upper fixing thread under the head clamps the decking board securely in place to eliminate creaking and board movement over time.
-
Small Countersunk Head with Milling Ribs: Reduced head profile with under-head pocket ribs countersinks cleanly into decking boards without mushrooming or splitting board edges.
-
Torx / Star Drive (TX): Precision star drive recess delivers maximum torque transmission and prevents bit slippage or driver cam-out during continuous driving.
-
Self-Tapping Piercing Tip: Sharp cutting tip with active thread geometry pierces wood fibers quickly for fast starting without splitting timber.
