Comprehensive analysis of expansion bolts, anchors and special anchors
In the fields of construction, decoration, electromechanical installation, etc., expansion bolts and various anchors are key connectors for fixing objects to substrates such as concrete and brick walls. The following is the classification, characteristics and application guide of common anchors.
1. Expansion bolts (Expansion Anchor)
Purpose: used for fastening hard substrates such as concrete and solid bricks.
Common types:
Metal expansion bolts (such as M6/M8/M10):
Material: carbon steel (surface galvanized), stainless steel (A2/A4)
Nylon expansion tube + screw:
Suitable for lighter loads (such as hanging pictures, sockets)
Easy to install and low price
Applicable scenarios:
Fix brackets, pipes, door and window frames to concrete walls
Heavy equipment foundation anchoring
2. Anchor Hook
Purpose: used for hanging objects (such as lamps, pipes, green plants).
Features:
One end is a threaded rod, the other end is a hook or ring structure
Material: galvanized steel, stainless steel
Installation method: pre-buried or post-expansion fixation
Common types:
Expansion anchor hook: direct drilling installation
Chemical anchor hook: requires injection of anchor glue, higher bearing capacity
3. Hollow Wall Anchor
Use: dedicated to hollow walls such as gypsum boards and hollow bricks.
Type:
Toggle Bolt:
With deployable metal wings, which are deployed after passing through the wall
Suitable for medium loads (such as TV stands)
Self-drilling hollow wall anchor:
Screw directly into the gypsum board without pre-drilling
Low load-bearing capacity (≤10kg)
Nylon sleeve anchor:
Tighten the screw after insertion, and the sleeve expands to fit the inner wall
Applicable scenarios:
Gypsum board partition wall installation of shelves, curtain rods
Lightweight partition wall fixing
4. Heavy-Duty Anchor
Purpose: High-load anchoring (such as steel structures, large equipment)
Type:
Chemical Anchor:
Bonded with epoxy resin or vinyl ester glue
Extremely high bearing capacity (single anchor can reach more than 10 tons)
Undercut Anchor:
Mechanical expansion of the bottom of the hole, strong pull-out resistance
Suitable for scenes with high seismic requirements
Anchor Bolt:
Buried in concrete, used for equipment foundation fixation
Applicable scenarios:
Fixed to the foot of the steel structure column of the factory
Anchoring of bridge and tower crane foundations
5. Water Heater Anchor
Features:
Usually made of stainless steel (rust-proof)
With waterproof gasket to prevent water seepage
Hook head design is convenient for hanging water heaters
Installation points:
Confirm that the wall is a load-bearing wall (concrete or solid brick)
Use an impact drill to drill holes, depth ≥ anchor length
Tighten after inserting the anchor hook to ensure full expansion
6. Anchoring tools
Electric hammer/impact drill: essential for concrete drilling
Torque wrench: precise control of bolt preload
Chemical anchor injection gun: used for resin anchor injection
Anchor installation auxiliary kit: ensures verticality of drilling
7. Slab Anchor
Purpose: used for connection between concrete slabs or crack repair.
