Black Oxide Carbon Steel Foundation Bolts for Foundation Fixing with Standard Industrial
Contact Supplier
Product Highlights
- Hooked Mechanical Anchoring: L bent hook gets locked inside concrete, generating strong grip to stop upper structures from shifting or lifting under heavy load.
- Foundation Displacement Prevention: Eliminate equipment/steel frame sliding risks; embedded L anchor bolts build rigid connection between concrete base and upper structures.
- 60% Higher Pull-out Strength: Hooked design improves anchoring tensile capacity by 60% compared with straight embedded bolts of the same diameter.
- Civil Engineering Versatility: Customizable dimensions deliver stable anchoring for factory steel frames, heavy machinery bases and outdoor infrastructure projects.
- Flexible Anti-corrosion Options: You can pick black oxide for indoor projects or hot dip galvanized finish for humid outdoor construction to extend service lifespan.

Product Description
Forged from premium Q235 carbon steel of grade 4.8, available with black oxide or hot-dip galvanized surface treatment. Special L bent hook design offers outstanding anchoring performance; rolled threads have stable fitting tolerance for nut assembly, steel body bears heavy static load without permanent deformation.
Functions
Pre-embedded inside concrete before pouring. After concrete solidifies, the hooked segment creates firm mechanical interlock, transfer upper structural load to foundation, prevent steel frames or machinery bases from shifting, tilting or separating from concrete under long-term load.
Applications
Widely used for steel workshop frame foundation installation, industrial equipment base fixing, highway guardrail foundation construction, tower and support embedded fastening works.
Advantages
Reliable high load anchoring performance, customizable length & thread sizes, multiple anti-rust surface options, mature construction application effect, cost-effective for large civil engineering procurement.
Structural Features
Its tail is bent into a hook shaped like the number 9, and external threads are machined on the shank to fasten components with matching nuts. The hook embedded in concrete creates strong mechanical interlock to resist pull-out force effectively.
2. Umbrella-handle Anchor Bolt
Structural Features
The tail is bent into an umbrella-handle hook; one end is the threaded exposed section, while the hooked end is pre-embedded inside concrete.
3. 7-type Anchor Bolt
Structural Features
The tail is bent at a right angle in the shape of number 7; the threaded section extends out of concrete for subsequent tightening installation.
4. Welded Anchor Plate Bolt
Structural Features
Anchoring steel plates are welded at the bottom of the screw; anchoring force is generated by the compression between steel plate and concrete, while threaded upper part is used to secure equipment.
Fix heavy machinery, stamping machines, generator sets, pump units and other equipment with continuous operation vibration or impact load, preventing bolt loosening caused by cyclic vibration.
5. Claw-type Anchor Bolt (Welded Claw Anchor Bolt)
Structural Features
Multiple spread anchor claws are welded at the screw tail, and the claws are embedded separately in concrete.
6. Anchor Bolt Cage
Structural Features
It is an integrated prefabricated part assembled by multiple anchor bolts, ring steel plates and reinforcing ribs into a cage structure, with threaded ends reserved on bolt tops. It works like tree roots to disperse foundation loads.
