Professional Applications & Engineering Value
These 18-8 stainless steel rounded head screws deliver critical performance advantages in demanding industrial settings. The combination of 100,000 psi tensile strength and Rockwell B100 hardness ensures reliable fastening under vibration and load stress, while the passivated finish provides enhanced protection against chemical exposure and atmospheric corrosion. The UNC coarse threading with Class 2A fit facilitates quick assembly in production environments, reducing installation time and preventing thread damage. Ideal for machinery, equipment manufacturing, and structural applications where corrosion-resistant fasteners must maintain integrity in challenging operating conditions. The fully threaded design maximizes contact surface area, distributing clamping forces evenly for superior joint stability.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit tolerance and UNC coarse thread profile (6-32 size). Complies with ASME B18.6.3 mechanical specifications and meets environmental regulations including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance. Features right-hand threading direction, standard rounded head profile, and slotted drive style for universal tool compatibility.
