Preface: Instead of this standard GB/T3632-1995 "steel structure with torsional shear type high strength bolt connection vice" and GB/T 3633-1995 Technical requirement for sets of torshear type high strength bolt hexagon nut and plain washer for steel structures "steel structure with torsional shear type high strength bolt connection deputy technical conditions". This standard and GB/T3632-1995 and GB/major changes such as compared T3633-1995 : - increase M27 and (thread specification and recommended materials: 35 vb, 35 crmo (see table 1 to table 6). - increase material: ML20MnTiB, ML35 (see 5.1 and table 6). - regulation by the supply and demand both sides agreement, can also be set by the table 6, material, but Should be indicated in the order contracts, and on the bolt or nut products add logo T (follow the S or H) (see 5.1, table 6 and 8.3); - to cancel the double chamfer nut type (GB/T 3632-1995 Sets of torshear type high strength bolt hexagon nut and plain washer for steel structures center 3 optional type); - the size of the thickness of the gasket code to (see figure 4 and table 5) ; - according to GB/T228 regulation, the relevant mechanical properties of the name and symbol for the corresponding adjustment (see table 7). - adjust the scope of the hardness of the nut (see table 11). - increases the connection of mechanical performance test sampling plan (see 7.3); Canceled the GB/T3632-1 995 appendix A, adding new appendix A. This standard is the national standard of steel structure bolted connection byproducts series standard, one of the series include: GB/T1228-2006 high strength large hexagon head bolts for steel structure; GB/T 1229-2006 High strength large hexagon nuts for steel structures steel structure with high strength large hexagon nut ; GB/T 1230-2006 High strength plain washers for steel structures steel structure with high strength gasket; GB/T 1231-2006 Specifications of high strength bolts with large hexagon head,large hexagon nuts,plain washers for steel structures steel structure with high strength and great hex bolt, hex nut, washer technology conditions; GB/T3632-2008 steel structure with torsional shear type high strength bolt connection. this Annex A is normative appendix standard. This standard put forward by China machinery industry federation. This standard by the national fastener standardization technical committee (SAC/TC85) under centralized. This standard is responsible for drafting unit: China metallurgical group in building research institute and machine productivity promotion center. In this standard drafting unit: Shanghai high strength Bolt factory, Shanghai ShenGuang high strength bolts co., LTD., Shanghai golden horse high strength fastener co., LTD., shandong high strength fastener co., LTD., hebei ren county high strength bolts co., LTD., China railway mountain bridge group high-strength fastening equipment co., LTD., ningbo fastener manufacturing co., LTD., Kowloon, gem-year industrial co., LTD., ningbo zhong jing united technologies Industry co., LTD., zhejiang xyron standard parts co., LTD., hangzhou hua LingGang structure of high strength bolts co., LTD. And anhui chaohu foundry co., LTD. This standard by the national fastener standardization technology committee secretariat is responsible for the interpretation. This standard replaced all previous releases of standard is: GB3632-83, GB /T3632-1995; ---GB3633-83GB/T 3633-1995 Technical requirement for sets of torshear type high strength bolt hexagon nut and plain washer for steel structures  
Description:This standard specifies the thread specification for steel structure with m16 ~ (torsional shear type high strength bolt connection vice type size, technical requirements, test method, marking method and acceptance and packaging. This standard is applicable to industrial and civil building, bridge, tower mast structure, boiler steel structure, hoisting machinery and other steel structure with torsional shear type high strength bolt connection.
