HEAVY HEX NUT

Short Description

Brand:- SAI or any general.

Standard hex nuts work fine for general assembly, but structural connections carrying serious loads often need something with more material behind the threads. A heavy hex nut is thicker and wider across the flats than a standard hex nut, giving it extra bearing surface and greater resistance to stripping under high torque. Genuine Enterprises manufactures this fastener under the SAI brand, and its added mass makes a heavy hex nut a common pairing with high strength bolts and studs in structural steel work, where the connection needs to hold up under significant tensile and shear loads over time.

Material: Carbon Steel, Alloy Steel
Grades: Grade 2H, Grade 8, and other grades available on request
Thread Type: Metric coarse thread or UNC as standard
Size Range: M12 to M64, with other sizes made to order
Profile: Thicker body with wider across-flats dimension than standard hex nuts
Surface Finish: Zinc Plated, Hot Dip Galvanized, Black Oxide
Standards: ASTM A194, DIN, ISO, and applicable structural specifications
