Self-undercut Anchor

Product Details

Self-undercut Anchor is supplied for concrete fixing, foundation anchoring, ceiling installation, equipment fixing, and building construction. The current supply reference is Project specification / approved drawing, with Carbon Steel / Stainless Steel, Zinc Plated / HDG / Dacromet, and M6-M24 1/4"-1".

Final dimensions, tolerances, grade or class, coating system, matched components, inspection documents and packing must be confirmed against the purchase order, approved drawing or project specification before production.

Where a European Technical Assessment (ETA) is required, confirm the assessment number, manufacturer, exact product and covered use before quotation. A generic product name or illustration does not establish assessed performance.

Selection & Use Steps

Confirm the base material, design load, fixture thickness and installation location.
Select anchor type, diameter, embedment and material from the approved engineering specification.
Check edge distance, spacing, hole diameter and drilling depth before installation.
Clean and prepare the hole, then install with the specified tool and procedure.
Complete the required inspection or proof test and record the installation result.
Where an ETA is specified, verify that its manufacturer, product identity, dimensions, substrate, intended use and installation conditions match the proposed anchor.

Technical Drawing

Confirm all dimensions against the approved drawing before production. Typical control points include overall length, diameter, thread series and tolerance, threaded length, end condition, head or point geometry where applicable, coating allowance and mating-part fit.

The technical drawing shown on this page, when available, is a selection reference and does not replace the buyer-approved manufacturing drawing.

Application Environment

Suitable application depends on the confirmed material, grade, finish and project design. Review exposure to moisture, chemicals, salt, temperature, vibration and dissimilar metals before selection.

For outdoor or corrosive service, confirm that the selected coating or stainless grade is compatible with the required service life and installation method.

Installation & Handling Precautions

Do not mix grades, heat numbers, thread series or nut classes during storage and installation.
Protect threads and coatings from impact, contamination and uncontrolled repair.
Confirm nut and washer compatibility, coating allowance and free thread engagement before assembly.
Do not apply a generic torque value; tightening depends on lubrication, coating, joint design and the approved engineering procedure.
Replace components with damaged threads, uncertain identification or unacceptable coating condition.
