Carbon Steel Black Gr8.8 Hexagon Head Hex Bolt


A bolt is a form of threaded fastener with an external male thread. Bolts are thus closely related to, and often confused with, screws. A hex cap screw is a cap screw with a hexagonal head, designed to be drivenby a wrench (spanner). An ASME B18.2.1 compliant cap screw has somewhat tighter tolerances than a hex bolt for the head height and the shank length. The nature of the tolerance difference allows an ASMEB18.2.1 hex cap screw to always fit where a hex bolt is installed but a hex bolt could be slightly too large to be used where a hex cap screw is designed in.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 platedProduction ProcessM2-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 GB5782Stainless steel: All DIN Standard stainless steel BoltFree Samples for standard fastenerFor more information visit:www.hainafastener.com
