What is SAE Fasteners?

SAE Fasteners are bolts, screws, nuts and washers manufactured to specifications published by SAE International (Society of Automotive Engineers), the leading standard for inch-series fasteners used in automotive and mechanical engineering. SAE J429 grading defines precise tensile strength, thread pitch (UNC/UNF) and material property classes such as Grade 2, Grade 5 and Grade 8, making SAE fasteners the trusted specification for vehicle assembly, engines and drivetrain components. Sterling Fasteners manufactures the complete SAE catalogue — hex bolts, hex nuts, washers and specialty automotive fasteners — under a single quality management system, giving buyers one supplier for an entire SAE bill of materials. Our production lines run dedicated inch-series threading and heat-treatment equipment, supported by an in-house metallurgical lab for grade verification. Whether you need a single SAE Grade 8 bolt size or a mixed container of multiple SAE standards, our export team consolidates documentation, packing lists and mill certificates into one shipment.
