Products Description
This anchor bolt combines a sleeve expansion mechanism with an integrated J-shaped hanging hook. Once installed, it mechanically expands and locks securely within concrete, brick, and block walls. It is capable of supporting the full weight of electric water heaters, storage-type water heaters, and large wall-mounted bathroom fixtures, offering high pull-out resistance, anti-slip stability, and impact resistance. Water Heater Expansion Hook Screws are standard fasteners used for bathroom plumbing systems, the suspension of household water supply equipment, and the wall-mounted installation of heavy objects in buildings.

Material & Grade Performance Explanation
1. Material Performance
Carbon Steel: Cost-effective mainstream material for conventional household water heater installation, stable tensile strength and expansion locking performance, meets daily static load weight bearing requirements for small and medium-sized water heaters.
Alloy Steel: Subjected to quenching and tempering heat treatment, with enhanced shear resistance, pull-out resistance and fatigue resistance, suitable for large-capacity commercial water heaters, heavy sanitary equipment and high-load industrial hanging installation.
2. Strength Grade Application Matching
Grade 4.8: For small household wall-mounted water heaters, light bathroom accessories hanging, low static load indoor suspension
Grade 5.8: Universal mainstream grade, standard household 40L–80L electric water heater fixed installation, balanced load capacity and cost performance
Grade 8.8: High-strength heavy-duty grade, 100L+ large capacity water heater, commercial hot water equipment, multi-device combined heavy hanging installation
