Product Description

PRODUCT PARAMETER

Self-Cutting Concrete Anchors

Overview
Self-Cutting Concrete Anchors are specialized fasteners for permanent, high-load attachment to concrete, masonry, or cementitious substrates. Unlike traditional expansion anchors, their precision-threaded cutting shank forms mating threads directly in concrete during installation—no pre-drilled, reamed holes needed—delivering robust resistance to pull-out and shear forces.
Construction & Materials
Shank/Head: Made of high-strength carbon steel (e.g., AISI 1045) or alloy steel, heat-treated for hardness (HRC 35–45) to cut concrete; spiral flutes clear debris.
Corrosion Protection: Hot-dip galvanization (HDG) for dry areas; 304/316 stainless steel for humid/chemical environments.
Compliance: Meets ANSI/ASME B18.6.3 (threads) and DIN 125 (tolerances).
Operating Principle
Drill a pilot hole (matching anchor diameter, depth = 1.0–1.5× anchor length).
Insert the anchor into the hole.
Torque with a wrench—cutting threads mill into concrete, forming a tight mechanical bond.
Key Applications
Construction: Secure steel beams, HVAC equipment, heavy shelving to concrete.
Infrastructure: Fasten traffic signs, guardrails, lighting poles to pavements/bridges.
Industry: Anchor machinery, conveyors, tanks to factory floors.
Core Advantages
No pre-expansion (avoids concrete spalling).
Faster installation (no hole reaming).
High load capacity (over 500kg pull-out, per ACI 318).
Versatile (works with C20+ concrete/masonry).
