304 stainless steel U-shaped double expansion anchors combine a closed U-loop with two independent sleeve-anchor legs, a bridge plate, nuts and washers. The twin fixing points help distribute the connection across the mounting plate while the polished stainless construction suits suitable indoor, outdoor and corrosion-conscious fastening projects. AODSON supplies drawing-based dimensions, materials, sleeves and inspection requirements for OEM and distributor orders.

Design and Installation Considerations
Anchor performance depends on the actual base material, hole diameter and cleanliness, edge distance, spacing, embedment, installation torque, loading direction and environmental exposure. The twin sleeves must be installed in sound, approved substrate using a qualified procedure. The complete connection—including the U-loop, nuts, plate, sleeves, substrate and surrounding structure—must be evaluated together.
Safety note: This product must not be treated as certified fall-arrest, rescue, climbing or personnel-suspension hardware unless the exact assembly has been engineered, tested, rated and approved for that purpose by the responsible qualified professional.

- Punching-bag and training-equipment supports
- Pipe, cable, bracket and building-service retention
- Custom indoor or outdoor anchor assemblies
Quality Control and Inspection
Inspection can include material verification, thread gauging, sleeve diameter and slot condition, plate dimensions, loop geometry, nut engagement, surface finish and assembly completeness. Project-specific proof testing, traceability or corrosion-related requirements must be defined before production; no load rating is inferred from nominal thread size alone.
OEM Customization and RFQ Information
For an accurate quotation, provide the assembly drawing, substrate type and strength, load direction and design requirement, thread and embedment dimensions, material grade, finish, quantity, inspection plan and packaging needs. AODSON can review stainless steel forming, machining, threading, sleeve production, polishing and final assembly for drawing-based programs.
Frequently Asked Questions
Are M6 × 90 and M8 × 100 available?
They are reference configurations visible in the supplied product information. Final thread, overall length, sleeve diameter and effective embedment must be confirmed before quotation or production.
Can this anchor be installed in brick or hollow block?
Do not assume compatibility. Expansion anchors require a substrate-specific review, and hollow, weak or cracked materials may need a different anchoring system.
Can it be used to suspend a person?
Not without an engineered and certified system. Personnel suspension, fall protection, rescue and climbing applications require purpose-rated hardware, verified installation and approval by the responsible qualified professional.
