Carriage Bolt:4.8grade zinc plated carriage bolt,4.8grade carriage bolt,DIN603,zinc plated carriage bolt,8.8Grade carriage bolt  A carriage bolt, coach bolt or round head square neck bolt is a form of bolt.It is distinguished from other bolts by its head: the shank of the bolt is circular for most of its length, as usual, but the portion immediately beneath the head is formed into a square section. This makes the bolt self-locking when placed through a square hole, or a round hole in most wood. This allows the fastener to be installed with only a single tool, a spanner or wrench, working from one side. The head of a carriage bolt is usually a shallow dome. The squared section is of the same size as the diameter of the bolt shank, with a plain unthreaded shank.Carriage bolts were developed for use through iron strengthening plates on either side of a wooden beam. It is commonplace though to use them into bare timber, the squared section giving enough grip to prevent rotation. Products nameBolts(Hex bolt,Heavy hex bolt,Flange bolt,Carriage bolt,Guardrail Bolt)Standard:DIN,ASTM/ANSI JIS EN ISO,AS,GBMaterialStainless Steel: SS201, SS303, SS304, SS316,SS316L,SS904L,F593Steel Grade: DIN: Gr.4.6,4.8,5.6,5.8,8.8,10.9,12.9;  SAE: Gr.2,5,8;  ASTM: 307A,307B,A325,A394,A490,A449,FinishingZinc(Yellow,White,Blue,Black),Hop Dip Galvanized(HDG),Black Oxide,Geomet,Dacroment,anodization,Nickel plated,Zinc-Nickel platedProductionProcessM2-M24:Cold Froging,M24-M100 Hot Forging,Machining and CNC for Customized fastenerCustomized ProductsLead timeBusy season:15-30days,Slack seaon:10-15daysStock ProductsSteel:4.8Grade DIN6923,8.8Grade 10.9Grade of GB5783 and GB5782  Stainless steel: All DIN Standard stainless steel BoltFree Samples for standard fastenerFor more information visit:hainafastener.en.made-in-china.comService Professional 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./* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
