Professional Applications & Engineering Value

These low profile socket head cap screws deliver critical engineering solutions where space constraints meet high-strength requirements. The black-oxide alloy steel construction provides excellent corrosion protection while maintaining the 140,000 psi tensile strength needed for demanding applications. The 3/8"-16 UNC coarse threads with Class 3A fit ensure rapid assembly and superior vibration resistance in machinery, automotive, and heavy equipment applications. The hex drive design combined with the reduced head profile allows for secure tightening in recessed or confined spaces where traditional fasteners would be impractical. These precision-engineered socket head cap screws solve common industrial challenges by providing reliable fastening performance while meeting strict dimensional and material specifications.

Specification Summary & Compliance

Manufactured to exacting Class 3A thread fit tolerances with 3/8"-16 UNC coarse threads and full threading along the 7/8" length. These screws conform to ASTM A574 specification for alloy steel socket head cap screws, ensuring consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for global industrial applications requiring adherence to strict material and safety standards.
