Nylon Screw In Plastic Spiral Expansion Anchors Self Drilling Insulation Fixing Plugs Large Diameter for Heavy Load
Product Description
The Large Diameter Nylon Screw-In Plastic Spiral Expansion Anchor is engineered for heavy load applications in concrete, solid brick, stone, and hard masonry substrates where standard-diameter anchors provide insufficient holding capacity. With extra-large diameters of 14 mm, 16 mm, and 20 mm and a thickened nylon PA6 wall, this anchor delivers substantially higher pull-out and shear resistance for structural and heavy equipment mounting applications. The deep spiral thread profile provides maximum mechanical interlock with the substrate borehole wall for critical anchoring points.
Designed for heavy shelving support, large wall cabinet installation, structural bracket anchoring, gate hinge and fence post mounting, and heavy equipment support, this large-diameter anchor is the high-capacity option in the nylon screw-in anchor range. Available in lengths from 50 mm to 120 mm to accommodate the deeper embedment required for high-load applications. Manufactured to ISO 9001:2015 standards with extra quality checks on thread profile consistency and wall thickness.
Features
Extra-large diameters of 14 mm, 16 mm, and 20 mm provide substantially higher load capacity. Thickened nylon PA6 wall handles higher screw torque and expansion force without deformation. Deep spiral thread profile ensures maximum mechanical interlock for critical anchoring points.
Suitable for heavy load applications that exceed the capacity of standard 6-12 mm anchors. Provides pull-out resistance approaching that of metal expansion bolts in suitable substrates. Ideal for structural bracket mounting and heavy equipment support where anchor failure is not acceptable.
Screw-in installation using a hex driver or power screwdriver for high-torque driving. Pre-drill the recommended hole size, then drive the anchor in with a power screwdriver. The spiral threads self-tap into the hard substrate borehole wall during installation.
Available in lengths from 50 mm to 120 mm for deeper embedment and higher capacity. Longer anchor body provides more thread engagement length and proportionally higher pull-out resistance. Select anchor length based on substrate thickness and required load capacity.
Ideal for heavy shelving supports, large wall cabinet installation, structural bracket anchoring, gate hinge and fence post mounting, and heavy equipment support. A high-capacity nylon screw-in anchoring solution for structural and industrial applications.
