Nylon Spiral Self Tapping Wall Anchor 10mm x 40mm Plastic Drywall Plasterboard Fastener with Conical Drill Tip for Lightweight Concrete
Product Description
The 10mm x 40mm Nylon Spiral Self Tapping Wall Anchor is a premium plastic fastening solution engineered for lightweight concrete / hollow block 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. Installation is straightforward: mark your desired position, place the conical tip against the wall surface, and drive the anchor clockwise using a screwdriver or impact driver. Stop when you feel resistance and the disc base is flush with the surface - typically takes just seconds.
Features
Micro-Serrated Tip - Fine serrations along the conical tip edge help initiate cutting action even in dense gypsum and cement-reinforced boards without skating or wandering.
Thread Zone Reinforcement - Reinforced thread ridges resist stripping under torque, ensuring reliable screw engagement even after multiple tightening and loosening cycles.
Oversized Bearing Washer - The wide circular bearing surface at the anchor base acts as an integrated washer, eliminating the need for additional hardware in most installations.
Food-Safe Nylon Grade - The anchor material complies with food-contact safety standards for use in kitchen cabinet mounting and food preparation area fixtures.
