DIN6915 10 Hv Heavy Hex Nuts also called structural nuts, are both thicker and wider than a standard (finished) hex nut and compatible with high strength and large diameter bolts. DIN6915 10 Hv Heavy Hex Nuts in sizes smaller than 7/16" are double chamfered. DIN6915 10 Hv Heavy Hex Nuts larger than 7/16" are either double chamfered or chamfered on top with a washer faced bearing surface.

DIN6919 Carbon Steel Black Flat Washers is one of our common standard washers, the material of carbon steel, the surface has black oxide,zinc plated. DIN6919 Carbon Steel Black Flat Washers is use with A394 high strength structural bolts. DIN6919 Carbon Steel Black Flat Washers, mainly punched out from iron plates. The common shape of a flat washer is a hole in the central. The pore size specifications according to customer requirements. high quality and lower price. Our company has certificates ISO9001.

ASTM A307b GRB Heavy Hex Bolts is a ASTM A307 models.The ASTM A307 specification covers carbon steel bolts and studs ranging from 1/4″ through 4″ diameter. This is your everyday, run of the mill bolt specification often manufactured using A36 round bar. There are three grades A, B, and C* which denote tensile strength, configuration, and application. Refer to the Mechanical Properties Chart for the subtle strength differences within each grade.

ANSI D-21 Hex Flange Nut provide a secure and tight fit, while also preventing the nut from loosening due to vibration. This is especially important in industries where machinery and other heavy equipment are used, as any loosening of fittings can cause dangerous and costly consequences. The flange of ANSI D-21 Hex Flange Nut acts as a washer, providing additional support while preventing the nut from embedding itself into the surface of the material being fastened. This greatly reduces the risk of damage to the structure, as well as providing a more aesthetically pleasing finish.

ANSI Hex Socket Screw is a hexagonal head that allows for easy tightening and loosening, and is made from high-quality steel for maximum durability. With its sturdy construction and robust design, ANSI Hex Socket Screw can withstand high levels of stress and strain, making it an ideal choice for heavy-duty applications. Made from high-quality steel, ANSI Hex Socket Screw is resistant to corrosion and rust, ensuring reliable performance even in harsh environments. ANSI Hex Socket Screw With its high strength, ease of use, versatility, and corrosion resistance, it is no wonder that it is a popular choice for a wide range of applications.

Shear Connector Welding Screw refer to the installation of steel pins or grommets, that extend out of the top flange of a steel support beam. Normally the Shear Connector Welding Screw are welded, with a spot welder, after the metal deck is installed over the supporting structural steel. The spot welder will burn through the metal deck and attach the Shear Connector Welding Screw directly to the top of the steel beam.
