Wedge Anchor

Basic Info

An Expansion Bolt is a post-installed anchoring fastener used to secure objects to solid base materials like concrete or masonry.It works by pulling a conical stud into an expansion sleeve,forcing the sleeve to expand radially within the drilled hole,creating immense friction and mechanical interlock.It is a fundamental component for equipment mounting,bracket fixing,and railing installation in retrofit and construction projects.

Customer reviews

James Carter · Maintenance Engineering Supervisor

The Grade 10.9 high-strength bolts from your company were used in our steel structure platform. After two years of full-load operation, all connections remain completely tight with excellent torque retention. Such stability in a high-vibration environment demonstrates outstanding anti-loosening and fatigue resistance, helping us avoid costly downtime for maintenance.

David Müller · Procurement & Quality Manager

As a procurement party, we value consistent quality in bulk products the most. The Grade 8.6 hex head bolts we purchased from your company showed almost no deviation in mechanical performance tests (hardness, tensile strength) across five consecutive batches, with a 100% pass rate in thread gauge inspection. This consistency greatly ensures the efficiency and safety of our assembly line.

Dr. Emma Fischer · Chief R&D Engineer

"In the development of precision optical instruments, we have strict requirements for fastener dimensional tolerances and magnetic properties. The non-magnetic stainless steel miniature bolts (M1.6-M3) provided by your company fully meet the drawing tolerance requirement of ±0.015mm. Their vacuum degassing process effectively prevents contamination of the optical system by micro-gas emissions."

Product Description

Product Characteristics:

Easy installation,no pre-embedding required,ideal for renovation and installation work.Holding power derives primarily from friction and mechanical lock with the base material,offering high reliability.Various designs exist:hammer-drive(expands via impact)and torque-controlled(expands via nut tightening).Performance heavily depends on base material strength,edge distance,and spacing;selection must follow design guidelines.

Product Specifications:

Typically specified as"Thread Diameter×Total Length×Embedment Depth,"e.g.,M10x100/75.Common diameters:M6 to M24.Materials:Carbon Steel(galvanized),Stainless Steel(A2,A4).For seismic/heavy-duty requirements,advanced types like chemical anchors(adhesive)and undercut anchors exist.

Product Applications:

Used to fix pipe supports,cable trays,ventilation equipment,AC outdoor units,railing posts,signboards,shelving,machine tool leveling feet,door/window frames to concrete walls or floors.An essential on-site fixing solution in building services,MEP(Mechanical,Electrical,Plumbing)installation,and interior finishing.
