ANSI A490 Balck Heavy Hex Bolts are specifically designed for use with heavy hex nuts in the connection of structural members (as opposed to tapped holes). ANSI A490 Balck Heavy Hex Bolts are strong heavy-duty bolts that are typically used for creating structures through steel to steel structural connections such as buildings and bridges. A grade 8 bolt would be one that meets ASTM A490 standards. The high quality steel used to create ANSI A490 Balck Heavy Hex Bolts are designed for strength and durability, allowing ANSI A490 Balck Heavy Hex Bolts to conform to ASTM A325. ANSI A490 Balck Heavy Hex Bolts are often applied alongside structural nuts and washers to metal beams and girders.

DIN127A Lock Single Coil Spring Washer are commonly used metric lock washers, As you tighten a bolt, these DIN127A Lock Single Coil Spring Washer flatten to add tension to the threaded joint and prevent loosening from small amounts of vibration. DIN127A Lock Single Coil Spring Washer meet a DIN or ASME standard for split lock washer dimensions. Standard DIN127A Lock Single Coil Spring Washer have a left-hand helix, which means you can only use them with bolts that have right-hand threads to prevent clockwise rotation from vibration. 

DIN960 Fine Thread Hex Bolts is a mechanical fastener with threaded shafts. The bolts are closely related to screws, which are also mechanical fasteners with threaded shafts. This type of fastener is usually inserted through two parts, which have aligned holes. By some definitions, whether a thing is a bolt or a screw depends on how it is used. DIN960 Fine Thread Hex Bolts is inserted through the parts that all have unshielded holes, and a nut is then screwed onto the bolt to provide a clamping force & prevent axial motion.

ASTM A193 B7 Carbon Steel Fully Thread Studs Thread Rod, These studs are made from premium-grade carbon steel that offers exceptional strength and durability.They come in a range of lengths and diameters to suit your requirements, and their fully threaded design ensures a secure hold for any application.ASTM A193 B7 Carbon Steel Fully Thread Studs Thread Rod have a thick coating for excellent corrosion resistance.

Hot DIP Galvanizing En14399-3 Bolt Hr is usually used with a nut and a washer, Hot DIP Galvanizing En14399-3 Bolt Hr has several types such as: En14399-3 En14399-4 En14399-5 En14399-6. En14399 is also DIN6914, Bolt and nut gaskets are used in combination. Hot DIP Galvanizing En14399-3 Bolt Hr is usually black. Bolts, nuts and gaskets have hr or hv.

Steel Structure Wedge Anchor are designed to tie the concrete slab with the steel beams and steel deck. This weld studs shear connectors can resist shear forces and increase shear loading capacity in steel buildings. Steel Structure Wedge Anchor Mainly applied for through steel deck stud welding in composite construction project. All Shear Studs are supplied with ceramic ferrules (ceramic ring). The Ceramic ferrules are made of cordierite and able to withstand heat shock as well as high temperatures without melting or breaking
