Product Description

Nylon Screw In Plastic Spiral Expansion Anchors No Pre Drill Self Tapping Insulation Fixing Plugs for Hollow Wall


 

Product Description

 

The No Pre-Drill Self-Tapping Nylon Screw-In Plastic Spiral Expansion Anchor is designed for hollow brick, hollow block, cavity walls, and fiber cement board substrates where pre-drilling is either inconvenient or risks damaging the thin web material of hollow units. The anchor features an enhanced self-tapping tip and aggressive spiral thread that can directly penetrate soft to medium-hard hollow wall materials without the need for a separate pilot hole. The deep spiral threads create a strong grip within the limited web material thickness of hollow bricks and blocks.

 

This anchor is ideal for electrical box mounting, plumbing bracket installation, light fixture attachment, and decorative panel fixing in hollow wall applications where conventional expansion anchors may spin, crack the thin cavity wall, or fail to achieve adequate grip. The nylon PA6 material provides excellent insulation properties and will not corrode in humid cavity wall environments. Available in 8 mm and 10 mm diameters with 35 mm to 60 mm lengths, it covers common hollow wall anchoring requirements.

 
 

Features

 

 

Enhanced self-tapping tip penetrates directly into hollow brick, hollow block, and cavity wall materials without pre-drilling. Saves installation time and eliminates the risk of over-drilling through thin cavity walls. Aggressive spiral thread creates a strong mechanical grip within the limited web material.
 
Deep spiral thread profile is specifically designed for hollow substrates with thin material webs. The threads engage the limited material available in cavity walls at multiple points along the anchor body. Provides reliable pull-out resistance even where conventional smooth-body anchors fail.
 
Manufactured from high-strength nylon PA6 with excellent electrical insulation and moisture resistance. Will not corrode in humid cavity wall environments or cause rust staining on wall surfaces. Lightweight design that does not add stress to thin cavity wall materials.
 
Simple screw-in installation with a standard screwdriver – just position the anchor and drive it in. No pre-drilling, no hammering, and no special installation tools required. Suitable for professional electricians, plumbers, and finishing trades.
 
Ideal for electrical box mounting, plumbing bracket installation, light fixture attachment, decorative panel fixing, and general hollow wall anchoring. A reliable self-tapping anchoring solution for hollow wall applications.
