Product Description

Heavy Duty Reinforced Thread Nylon Spiral Expansion Anchors High Grip Screw In Wall Fixing Plugs for Hollow Brick Block

Product Description

The product is a heavy-duty screw-in spiral expansion anchor specially engineered for medium to heavy load applications on hollow brick, hollow concrete block, and perforated clay brick substrates. It features a thickened nylon sleeve with reinforced double-spiral thread profile that provides significantly enhanced expansion force and pull-out resistance compared to standard spiral anchors. The deeper thread grooves and thicker sleeve walls work together to create a powerful mechanical interlock inside the void chambers of hollow substrates. When the matching high-strength screw is driven in, the sleeve expands uniformly along its entire length, distributing the load across multiple contact points within the hollow chamber for maximum holding power. This anchor is ideal for mounting wall cabinets, TV brackets, heavy shelving, bathroom fixtures, and other demanding installations.

Features

Reinforced double-spiral thread design with 30% deeper groove profile creates stronger mechanical expansion force and superior holding power in hollow brick and block substrates.

Thickened PA6 nylon sleeve walls (0.8 mm thicker than standard) prevent cracking under high installation torque, ensuring reliable heavy-duty performance for demanding applications.

Achieves stable pull-out load for medium to heavy fixtures such as wall-mounted cabinets, TV wall brackets, bathroom grab bars, kitchen shelving, and water heater brackets.

Compatible with larger M4 to M6 self-tapping screws, providing expanded load capacity options to match different fixture weight requirements.

Uniform expansion along full sleeve length ensures even load distribution across the hollow chamber, preventing point-load failure common with short standard anchors.

FAQ

What makes the heavy-duty spiral anchor different from your standard anchor?

The heavy-duty version features a 30% deeper thread groove profile, 0.8 mm thicker sleeve walls, and modified high-impact PA6 nylon material. These improvements deliver approximately 50% higher pull-out resistance and prevent cracking under high installation torque, making it suitable for wall cabinets, TV brackets, and bathroom fixtures.

Can these heavy-duty anchors be used on drywall and plasterboard?

Yes, they are backward compatible with gypsum board and plasterboard. However, for light to medium loads on drywall, our standard spiral anchors offer a more economical solution. The heavy-duty version is optimized for hollow brick, hollow concrete block, and aerated concrete where higher holding power is required.

What screw sizes are compatible with the heavy-duty anchor?

The heavy-duty sleeve is designed to accommodate M4, M5, and M6 self-tapping screws. For maximum holding strength, we recommend using M5 or M6 screws with a minimum embedment depth of 30 mm into the substrate. Standard wood screws and chipboard screws are also compatible.

Can I get free samples for quality checking?

Free samples are available, customers only need to bear the freight; sample size and quantity can be arranged according to your requirement.
