Carbon Steel Stainless Steel DIN912 Black 12.9 High Strength Fasteners Cylindrical Head Hex Socket Bolt Hex Flange Bolt Hexagon Bolt

Carbon steel Stainless steel DIN912 Black 12.9 high strength fasteners Cylindrical head hex socket bolt hex flange bolt hexagon boltHexagonal cylindrical head bolts have 4.8, 8.8, 10.9, 12.9 levels. Also called hex screws, also called hex bolts. Its head is hexagonal head, but also cylindrical head. There are stainless steel and iron by material. Stainless steel has stainless steel SUS202 hex cylindrical head screws, this is stainless steel ordinary material, there are stainless steel SUS304 hex cylindrical head screws, there are stainless steel SUS316 hex cylindrical head screws.According to the strength of the hex cylindrical head screw, there are 4.8 hex cylindrical head screws, 8.8 hex cylindrical head screws, 10.9 hex cylindrical head screws, and 12.9 hex cylindrical head screws. 8.8-12.9 class hex cylindrical head screws are called high-strength and high-grade hex bolts.Technological process1. Drill holes according to the diameter of the other side of the hexagonal to the requirements.2, use the cold header to forge out the hex.3, a single piece can be hexagonal punch, with a hammer out.useSimilar to countersunk head screws, the nail head is embedded in the machine, the connection strength is larger, but the screw must be installed and removed with the corresponding specification hex wrench. Generally used on various machine tools and their accessories.   Products nameBOLTS, NUTS, WASHERS, SCREWS, THREADED ROD, ANCHOR BOLTS, STAMPING PARTStandardDIN,ASTM/ANSI JIS EN ISO,AS,GBMaterialCarbon Steel, High Strength Steel,Stainless Steel: SS201, SS303, SS304, SS316,SS316L,SS904L ,SS31803 Steel 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),Hot Dip Galvanized(HDG),Black,Geomet,Dacroment,anodization,Nickel plated,Zinc-Nickel platedProductionM2-M24:Cold Froging,M24-M100 Hot Forging,ProcessMachining and CNC for Customized fastenerCustomized ProductsBusy season:15-30days,Slack seaon:10-20daysLead timeStock ProductsStainless steel: All DIN Standard stainless steel fastener(BOLTS,NUTS.SCREWS.WASHERS)Fress Samples for standard fastenerHebei Senkuo Fastener Co., Ltd.
