Yellow Passivated Adjustable Frame / Distance Screw with Hexagon / Drive Recess (Fischer Frame / Floorboard Distance Screw)

A specialized dual-thread yellow passivated steel screw featuring two separate threaded sections, designed for leveling timber battens, subfloor joists, and wooden frame constructions without requiring shimming.

  • Dual-Thread Levelling Function: Two separate thread sections maintain precise clearance between timber members, allowing quick non-compressible distance adjustment and surface leveling.

  • Yellow Passivated Finish: Electro-galvanized yellow chromate surface coating offers interior corrosion protection while blending seamlessly with natural timber.

  • Countersunk Head with Retention Thread: Upper thread under the head locks the outer wood board securely in place while the head sits flush with the timber surface.

  • Coarse Anchoring Thread & Sharp Point: Deep primary thread and piercing tip provide strong pull-out resistance in solid wood, chipboard, or timber joists.
