Grade 8 Square Head Bolt

A Grade 8 square head bolt is a high-strength fastener designed for demanding applications that require superior tensile strength and resistance to shear forces. Here are the key characteristics of a Grade 8 square head bolt: Material: Grade 8 square head bolts are typically made from alloy steel, which provides exceptional strength and durability. Mechanical Properties: They have a significantly higher tensile strength than Grade 5 bolts, making them suitable for applications where extreme strength and reliability are critical. Square Head: The bolt head has a square shape, offering a large bearing surface and facilitating easy tightening with a wrench or pliers. Thread: Grade 8 square head bolts have a coarse thread pattern, making them suitable for applications that require quick assembly and disassembly. Grade 8 square head bolts are commonly used in industries such as automotive, construction, and heavy machinery, where the highest level of tensile strength and reliability is necessary. Their square head design ensures ease of use with standard tools while providing a secure and robust connection.
