There are three basic styles of wedge anchors: fully threaded, partial threaded and the full-bodied wedge anchor.[4] As shown in the figure, tightening the bolt results in a wedge being driven up against a sleeve. This jams the end of the bolt, and provides the strength. Many different manufacturers provide a variation on this theme, usually depending on the condition of the concrete, and the type of load. If a mechanical anchor fails, it is usually in the form of pulling out a wedge of concrete, and for this reason, proper design looks at the depth of embedment and ensures that the bolts are not spaced too closely.A specialized form of the anchor bolt is the rock bolt, used in rock excavations. In many parts of the world seismic anchors are another specialized subject. Products nameWedge anchor,Drop in anchor, expension bolt,shield anchor,Chemilcal anchor,Hollow wall anchor,Sleeve anchorStandard:DIN,ASTM/ANSI JIS EN ISO,AS,GBMaterialStainless Steel: SS201, SS304, SS316Steel Grade: DIN: Gr.4  SAE: Gr.2;FinishingZinc(Yellow,White,Blue,Black),Hop Dip Galvanized(HDG),Black Oxide,Geomet,Dacroment,anodization,Nickel plated,Zinc-Nickel platedProductionProcessCold forging,Stamping and assembledCustomized ProductsLead timeBusy season:15-30days,Slack seaon:10-15daysStock ProductsCarbon steel:Drop in anchor.wedge anchor.Shield anchor,expension boltStainless steel: All DIN Or GB Standard stainless steel anchorFree Samples for standard fastenerFor more information visit:hainafastener.en.made-in-china.comServiceProfessional Manufacturer: All of our Fastener are designed and manufactured according to buyers'    specification and performance.Quality is guaranteed: Durability testing and critical technical design to enhance fasteners lifetime.Cost effective: Competitive prices with factory directly supplyPerfect fastening solution with 20 years experiences to solve your problem: Wide range of parts selection.Customized Ideal Fasteners: customized services according to the samples and drawings offered.If you are not sure about what exactly you need - feel free to contact us anytime and get professional assistance from us.
