Plain Grade 8.8 Steel Double End Threaded Studs
Double end threaded studs are used in automotive applications to secure parts together with threaded connections on both ends. They feature Grade 8.8 steel construction for superior resistance to mechanical forces (tension, compression and shear) and ensure secure and reliable connections. They are offered in plain finish for easy identification, cost-effectiveness and resistance to corrosion, making them suitable for outdoor conditions. They have right hand threading to minimise the risk of accidental disassembly. These studs are available in Rockwell C22-C32 & C22-C34-rated variants. The studs featuring a Rockwell C22-C32 rating provide enhanced durability and resistance to wear, while the fasteners with a Rockwell C22-C34 rating offer superior hardness and toughness, ensuring reliable performance in demanding applications.
