Hot Sale for Drilling Lag Bolts Into Concrete - Mechanical Anchor Bolt,undercut Anchor Bolt,zinc Plated, Used For Non-cracked And Cracked Concrete. – Gusen

GUSEN undercut anchor bolt, combined with the advantages of the post-install anchor bolt, has the performance of embedded bolts, at the same time, more flexibility and can be loaded immediately, can help to install quickly and reliably, without other bottom cutting tools or additional operations, Fastening bearing structure is suitable for heavy pipe, safety guardrail, industrial machinery, crane handrail, dormitory structure, anti-collision guardrail, roof fixing, lift track, bridge renovation etc

Undercut Anchor is a heavy-duty self-cutting mechanical anchor for hardened concrete.Undercut anchors are not your typical anchors. The bottom of the hole has a notched opening, or undercut, made either with a special drill bit or with an anchor that has a drilling device at the end of the bolt. When in place, the anchor uses the compressive strength of the concrete to resist the load, unlike a wedge anchor, which relies on the concrete’s tensile strength.

anchor is a post-installed structural anchor designed for static, dynamic and seismic loading in the tension zone of both cracked and uncracked concrete.The anchor bolt is often used in bridge, railway, tunnel, subway, all kinds of pipe and cable bracket installation fixed, so the quality of production requirements are very high.

Self-undercutting facilitates fast and reliable installation without the need for a separate undercutting tool or additional operations.Combines the advantages of a post-installed mechanical anchor, flexibility and immediate loading, with the performance of a cast-in-place headed stud

Close spacing and small edge distance thanks to low expansion forces.The resulting keying effect provides a secure hold even in cracked concrete under dynamic loading.

undercut anchor provides mechanical interlock with the concrete, rather than frictional grip inside the hole typical of expansion anchors. Spring-loaded steel segments snap out into the undercut at the bottom of the hole, and the steel will remain clamped for the whole of its working life. In addition, the design allows reduced edge distances and center spacings without losing performance.
