Product Description Product DescriptionOur Tension control bolt (TC bolt) is a heavy duty bolt used in steel structure. The head is usually domed and is not designed to be driven. The end of the shank has a spline on it which is engaged by a special power wrench which prevents the bolt from turning while the nut is tightened. When the appropriate tension is reached the spline shears off. Many worldwide projects use our TC bolts, such as Shenzhen Ping An Building(599 meters high)Hongkong-Zhuhai-Macau Bridge (55km long) Product NameTension Control Bolt/Nut/Washer AssembliesPlace of OriginHangzhou ChinaMaterialML40Cr(bolt),SWRCH45K(nut),45#(washer)Surface treatmentHot-dipped galvanized, Dacromet, Black oxide, Phosphorus saponificationGrade (ASTM F2280)A490TC Grade 8Grade (ASTM F1852)A325TC Grade 5Grade (JSSII-09-1996)S10TGrade(GB)8.8/10.9/12.9Diameter(inch)1/2, 5/8, 3/4 , 7/8, 1, 1 1/8, 1 1/4, 1 3/8, 1 1/2Length(inch)1~20 or customizedDiameter(metric)M12,M14, M16,M20,M22,M24,M27,M30,M33,M36Length(metric)30~400mm or customizedHead MarkingHYZ or CustomizedCertificatesCE,SGS,ISO 9001,FPC BC1Available standardASTM F2280,JSSII-09-1996, EN14399, GB/T3632-2008 Installation Instructions Certifications Packaging & Shippinga.Cartons+wooden pallets1. 25 kgs per carton, 48 cartons/1200KG per pallet.2. 1 x 20' GP container can load about 16-20 pallets.b.Barrels and wooden cases1. 200 kgs per drum,6 drums/1200KG per pallet.2. 1 x 20' GP container can load about 16-20 pallets.Company ProfileHangzhou Jiaxiang Gaoqiang Bolts Co., Ltd. is founded in 2007 with registered capital of RMB 30 million and is professionally engaged in manufacturing high-strength bolts with large hexagon heads for steel structures, torsion and shear type high strength bolts and shear studs.Located in Jinhua Industrial Park, Xiaoshan District, Hangzhou City, our plant covers an area of 22,000 square meters with convenient transportation and beautiful environment.
