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 O'Connor · Equipment Maintenance Director

"Our food processing production line requires frequent disassembly and cleaning. For five years, your company's A4-80 stainless steel socket head cap screws have shown no thread galling or corrosion failure in high-temperature, high-humidity environments. The excellent chloride ion corrosion resistance has extended our equipment maintenance cycle by 30%."

Sophie Clark · Equipment Maintenance Manager

For the upgrade of our beverage filling equipment, we needed A2-70 stainless steel bolts that meet hygiene standards. Your products not only come with complete material certificates but also feature smooth, burr-free heads and threads, effectively preventing hygiene dead corners. After multiple CIP (Cleaning-in-Place) cycles, the appearance remains as bright as new.

Arjun Patel · Chief Mechanical Engineer

We needed to replace special flange connection bolts for an old imported machine, which had non-standard dimensions and required controlled head weight. Your technical team responded quickly, providing a custom solution that fully met the dimensional and performance requirements while achieving weight reduction through optimized head design, solving our urgent technical challenge.

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.
