Description

Nylon Spiral Self Tapping Wall Anchor 12mm x 50mm Plastic Drywall Plasterboard Fastener with Conical Drill Tip for Cavity Wall

Product Description

The 12mm x 50mm Nylon Spiral Self Tapping Wall Anchor is a premium plastic fastening solution engineered for cavity wall / double plasterboard applications. Featuring a sharp conical drill tip and helical spiral body structure, this self-tapping anchor can be screwed directly into the wall surface without pre-drilling a pilot hole. The pointed tip easily penetrates soft wall materials, while the deep spiral threads cut precise grooves into the substrate, creating a secure mechanical lock. A flared disc-shaped base at the anchor bottom provides excellent support against the wall surface, preventing pull-through and ensuring a flush, stable mount. The self-tapping mechanism eliminates the need for separate drilling operations. Just position the pointed cone tip at your marked point, apply gentle pressure, and turn clockwise. The anchor cuts its own precision hole and threads in one smooth motion.

Features

Aggressive Cutting Edge - A sharpened lead-in thread edge acts as a cutting flute, clearing material efficiently as the anchor advances into cement board and dense substrates.
Full-Length Spiral - Spiral threads run the entire anchor body length for uniform engagement from surface to tip, maximizing grip in varying wall thicknesses.
Heavy-Duty Base Flange - The reinforced thick flange withstands high clamping forces for mounting heavy fixtures like wall-mounted TVs, radiators, and large shelving units.
Chemical Resistant - PA6 nylon resists degradation from common household chemicals, cleaners, and mild acids, ensuring reliable performance in utility rooms and garages.
