ABOUT THE PRODUCT

Product Overview

Anchor bolts (also called foundation bolts) securely fasten heavy structures to concrete foundations. Manufactured from high-quality carbon and alloy steel with precision threads, they are the critical connection between steel columns, transmission towers, equipment and their concrete bases.

Wide specification range — from M14 to M140, with strength grades covering 4.8, 5.6, 8.8, 10.9 and 12.9. Available in L-type, J-type and welded plate configurations. Custom production per your drawings is also available.

Every bolt undergoes strict quality control, including hardness testing, tensile strength testing and dimensional inspection, to ensure compliance with national and international standards.

L-Type Anchor Bolt
Bent end delivers strong, reliable anchoring force
J-Type Anchor Bolt
Hooked end for higher pull-out resistance
Welded Plate Anchor Bolt
Base-plate welded type for heavy-load equipment

INSPECTION STANDARDS

Quality Assurance

01
Hardness Test
Rockwell and Brinell hardness testing on sampled batches confirms heat treatment meets the required grade specification.
02
Tensile Test
Universal testing machine trials verify yield strength and ultimate tensile strength against standard values.
03
Dimension Inspection
Thread gauges, calipers and length measurement inspect every piece to keep tolerances within standard limits.
